应用
便携式测振仪主要应用于一般情况下的机械振动测量。尤其适用于设备状态监测方面。
各种机械振动的振源主要来自于结构设计、制造、安装、调试和环境本身。振动的存在必然要引起结构疲劳损伤、零部件磨损和冲击破坏等故障。对于低频振动,主要应考虑疲劳强度破坏性质的位移破坏;对于1KHz以上的高频振动,主要应考虑冲击力和共振破坏。理论证明,振动部件的疲劳与振动速度成正比,振动所产生的能量与振动速度的平方成正比,能量传递的结果造成磨损和其它缺陷。因此,在振动判定标准中,无论从疲劳损伤还是磨损等缺陷来说,以速度标准最为适宜。

The SM-5B strain gauge is intended primarily for long-term measurements on steel structures such as arches, joists and prefabricated tunnel linings. It is also used to monitor strain changes on concrete or rock surfaces using mounting blocks grouted or embedded in the surfaces.The gauge consists of a length of high strength wire clamped at both extremities into two threaded end pieces. Two hex nuts on each threaded end piece are used to fasten the gauge to anchor blocks. The anchor blocks hold the gauge in place on the structure under study. They are welded, bolted, bonded or mechanically clamped in place. A waterproof removable coil/magnet assembly fits on a construction at the center of the stainless steel tube in which the wire isenclosed. A thermistor is incorporated as a standard feature inside the coil/magnet assembly. Changes in length between the two anchor blocks and gauge temperature are measured with a digital readout.The initial gauge reading can easily be adjusted by the operator on-site to optimize gauge reading in tension or in compression.The relevant dimensions of the SM-5B vibrating wire surface strain gauge attached to its mounting blocks are shown in Figure 1.Figure 1: SM-5B vibrating wire strain gauge description and dimensionsTo mount the gauge on steel structures, the anchor blocks are set onto the spacer bar (described below), to provide the required spacing before they are welded to the structure. After welding, the spacer bar is removed and replaced by an actual gauge with a separate coil/magnet assembly mounted over the gauge to excite the gauge and measure the response. The wire is tensioned to the required level using the nuts mounted on the threaded end pieces. The mounting blocks can also be bolted to the steel structure or, in rock or concrete structures, grouted into shallow holes.1.1 STRAIN GAUGEThe nominal strain range of the SM-5B strain gauge is 3,000 microstrains. The wire is attached to the threaded end pieces of the gauge by hydraulic crimping.Figure 2 is a plot showing a typical strain range of the SM-5B gauge with the NORMAL reading shown plotted against the LINEAR reading.Figure 2: SM-5B strain range vs period1.2 READINGSThe SM-5B vibrating wire strain gauge can be read with the MB-6T or MB-6TL portable readout units or with the SENSLOG Data Acquisition System.2 INSTALLATION PROCEDURESM-5B gauges are supplied fully sealed with the coil/magnet assembly separate, and with the wire pretensioned. The SM-5B coil/magnet assembly also contains a thermistor whichPage 2Page 3is read using the MB-6T readout. It is suggested that a preliminary check of both the vibrating wire and the thermistor be carried out to verify the gauge lead cable and readout. Connect the wire leads to the readout box as follows:A complete description of the readout procedure is contained in the MB-6T or MB-6TL instruction manuals.In all cases, the gauge should not be operated or checked at values lying outside the range shown in Figure 2.The initial uninstalled N reading of the pretensioned gauges should lie within 1,200 to 1,300 microseconds, which corresponds approximately to the mid-range of the gauge. At the time of installation, the initial setting can bechanged to suit the magnitude and direction of the expected change in strain (see Figure 2).The correct resistance readings between the conductors in the lead cable are:If the correct resistance is not obtained, check for faulty connections or possible damage to the cable. If required, consult Roctest for repair or replacement.2.1 GAUGE LENGTH ADJUSTMENTBefore fastening the anchor blocks to the structure they must be mounted onto the spacer bar to ensure correct spacing. The two blocks are mounted over the ends of the spacer bar and the locking nuts are set handtight, while holding the anchor blocks against a flat surface to maintain proper alignment as shown in Figure 3.Page 4Figure 3: Use of the spacer bar for correct anchor block spacing2.2 ATTACHMENT OF ANCHOR BLOCKSThe SM-5B gauge is attached to anchor blocks which can be fastened to the surface to be studied by a variety of methods.2.2.1 WELDING ONTO METAL SURFACEWelding is the standard technique for mounting the SM-5B gauges. First, install the anchor blocks on the spacer bar as described before. The spacer bar with anchor blocks is then firmly held against the surface to which the blocks are to be welded. First, tack all four (4) edges, avoiding excessive heat. Then, firmly weld in place as in the sequence shown in Figure 4. Tap each block lightly after they are welded in place.Allow the anchor blocks and spacer bar to cool. Then loosen the nuts and lift out the spacer bar.Figure 4: Welding sequence for anchor blocks2.2.2 BOLTING TO STEELWORKSSpecial mounting blocks can be bolted to structural steelworks by single bolts welded onto the mounting blocks and tightened from the underside of the steelworks. Special figs are supplied to ensure correct hole spacing.2.2.3 FASTENING TO ROCK OR CONCRETE SURFACESIt is best to place the mounting blocks in the concrete before it sets. Mounting blocks for placement in concrete are equipped with short lengths of reinforcing steel bars. Where this is not possible, such as in rock, shallow holes can be drilled into the rock and the rebar mounting blocks, grouted in the holes using cement or cold setting epoxy resin. To ensure correct spacing, the same jig as described for the welding sequence is used to set the anchors on the spacer bar.2.2.4 EPOXY BONDINGUnder certain circumstances, it may not be feasible to use any of the above mentioned techniques to attach the anchor blocks, in which case bonding may be considered. The gauge puts a maximum 3.2 kg force on the anchors, so bonding using cold setting epoxy resins is a practical technique.Weldable mounting blocks may be epoxied to any type of surfaces (metallic, concrete, rock, etc.) using the positioning jigs described above to set the mounting blocks correctly.A good bond will be attained only if the surfaces are clean, dry and sound (free of flakes). The anchor blocks must be degreased using acetone (or an equivalent), and sanded to remove the cadmium plating on the lower surface. Weights or clamps may be used to hold the anchor blocks in place until the epoxy has set.2.3 GAUGE INSTALLATIONThe coil/magnet assembly is supplied in two halves that snap into place about the crimped section of the gauge body. The thinner section goes on the underside of the gauge body up against the structure. The thin section must be set under the gauge body before the gauge is slid into final position in the second end block.1. Clip the 2 parts assembly over the strain gauge. Clamp the two halves together withthe hose clamp, and connect it to the readout.2. After the anchor blocks are mounted in place, the strain gauge is positioned in them bybacking off the four threaded end piece nuts to provide the necessary clearance. Flats are cut in the threaded end pieces to prevent them from rotating in the anchor blocks.Tighten one of the threaded end pieces in its anchor block by tightening the two nuts, one on each side of the anchor block. Use Loctite cement to prevent the nuts from loosening.3. Referring to Figure 5, turn nut 1 to tension the wire to the pre-determined value. In theNORMAL mode, the reading should be between 1,000 and 2,000 µseconds. The actual initial reading will depend upon whether or not tensile or compressive strains arePage 5Page 6to be measured; refer to Figure 2. When in doubt, set the initial reading to mid-range. 4. Once the reading has been selected, tighten nut 2 against the mounting bracket. Thereading may shift 50 units during tightening. The reading can be re-adjusted by re-tightening or slackening nut 2. When both nuts are tight, apply Loctite to prevent loosening.Figure 5: SM-5B installation procedure2.4 GAUGE AND LEAD WIRE PROTECTIONThe amount of protection depends on the type of installation and the environmental conditions. ROCTEST TELEMAC supplies a variety of accessories for this purpose. Gauges may be protected by cover plates bolted over the top of the gauge. Studs may be tapped directly into the work surface, or they may be glued, grouted or welded to the surface. The studs go through holes in the cover plate, which is then retained in place by nuts. Studs should not be positioned within 6 inches of the strain gauge, nor should the cover plates be tightened down hard, as this may induce non-uniform strains.It is usual to run the leads from different gauges to a central measurement station such as the SENSLOG Data Acquisition System, and to connect them to terminal boxes for easy reading. Where required, a conduit should be provided to protect the lead wires, particularly if shotcreting is to be used.3 MB-6T READINGSThe vibrating wire strain gauge is set to an initial tension during its installation. This initial value must be subtracted from subsequent readings to determine strain change in the surface under study. To read the SM-5B gauge, follow the instructions given in the MB-6T or MB-6TL instruction manuals. The readout displays two readings: the NORMAL mode reading (N value) and the LINEAR mode reading (L value).3.1 NORMAL READINGS (N)The change in strain in the surface under study on which the SM-5B is mounted is givenby the following formula:Page 7∆ε=-=⨯-⎡⎣⎢⎤⎦⎥εε10912021011K N Nwhere: ∆ε= strain change in μstrains in the surface under study K= gauge constant = 4.0624N 0= initial reading in NORMAL mode (in μseconds) N 1= current reading in NORMAL mode (in μseconds) ε1 = current strain corresponding to N 1ε0=current strain corresponding to N 0.3.2 MB-6T LINEAR READINGS (N)To determine the strain change in the instrumented structure from LINEAR readings, the following equation is applied:()∆ε=-LL 1where: ∆ε= strain change in μstrains in the structure L 0= initial reading in LINEAR unitsL 1= current reading in LINEAR units.Decreasing L values correspond to a negative ∆ε and are equivalent to a contraction of the structure.4 SPECIFICATIONSPage 85 MISCELLANEOUS5.1 CONVERSION FACTORS*at 4 ︒C E6TabConv-990505Conversion FactorsPage 95.2 THERMISTOR: TEMPERATURE READINGPage 10Temperature reading (Continued)Temperature readingPage 11。
