商用车悬架系统振动电测试验规范

商用车悬置系统电测试验规范编制:校对:审核:批准:****汽车有限公司技术中心编制20** 年 ** 月 ** 日悬架是安装在车桥与车架之间的。
悬架在振动的传递路径中起减震作用。
路面对轮胎产生的激励通过车桥、冲击,通过车桥、悬架系统传递到车架、驾驶室,再通过驾驶室传递到座椅。
如果悬架设计不当,最终传递到座椅处的振动较大,从而影响司机和乘客的乘坐舒适性。
悬悬架系统的设计是减小整车振动和噪声的一项关键技术,汽车悬架系统隔振率分析不仅是产品开发中结构分析的一项主要内容,而且是控制汽车常规振动噪声的关键指标,应作为产品开发的强制性考核内容。

典型的悬架结构由弹性元件、导向机构以及减震器等组成,个别结构则还有缓冲块、横向稳定杆等。
弹性元件又有钢板弹簧、空气弹簧、螺旋弹簧以及扭杆弹簧等形式,而现代轿车悬架多采用螺旋弹簧和扭杆弹簧,个别高级轿车则使用空气弹簧。
汽车悬架性能是影响汽车行驶平顺性、操纵稳定性和行驶速度的重要因素。
因此,研究汽车振动,设计新型悬架系统,将振动控制到最低水平是提高现代汽车质量的重要措施。

关键词:大学生方程式赛车;悬架系统;结构设计;仿真优化Design and Study of Suspension for a FSC CarAbstractThe design and optimization of suspension system is an essential part of the overall design for a race car. This design takes the suspension system of FSC race car designed by the race team ,which is from Beijing institute of technology, Zhuhai, as the research objective. The the design mainly work in several aspects. This design was based on the competition rules of FSC. The calculation of the wheel track and spread of axles as well as the design of some related components including the front and rear suspension column have been conducted after a clear idea of the design had been made. The next step is the analysis of wheel alignment parameters in order to make out whether it affects the performance of the car. When unequal-length wishbone suspension is selected, the paper chose the type of flexible components, absorder, guide mechanism and other parts, and make sure it in the line with some basic principles. After that, we established 3D model with the help of the software of CATIA. Finally, based on the simulation platform of ADAMS, the kinematics simulation model of racing car suspension was established, and the simulation analysis was carried out. After the suspension parameter model was obtained, the results of primary parameters were used to analyze, and the suspension parameters were optimized by ADAMS.Keywords: FSC Race Car; Suspension system; Design of Structure;Simulate and Optimize目录1绪论 (1)1.1本设计的目的与意义 (1)1.2FSC大赛概况 (1)1.3国内外方程式赛车悬架的研究现状 (2)1.3.1国外研究现状 (2)1.3.2国内研究现状 (3)1.4设计研究的主要内容 (3)1.5本章小结 (4)2悬架系统设计 (5)2.1设计原理与思路 (5)2.2悬架形式的确定 (7)2.3相关部件的设计与选型 (8)2.3.1轮辋与轮胎的选型 (8)2.3.2车轮定位参数 (8)2.3.3 轴荷比、轴距与轮距的设计 (9)2.3.4 悬架导向机构的设计 (10)2.3.5 性能参数的计算 (11)2.3.6 前后悬架立柱的设计 (13)2.3.7 减震器的选型 (13)2.3.8悬架基本参数 (15)2.4章节小结 (16)3 悬架三维建模与装配 (17)3.1悬架零部件的三维建模 (17)3.2悬架的装配 (18)3.3章节小结 (19)4 ADAMS悬架建模与仿真 (20)4.1悬架动力学建模 (20)4.2悬架仿真 (21)4.3仿真结果分析 (23)4.4章节小结 (25)5硬点坐标的优化 (26)5.1仿真结果优化 (26)5.2优化前后结果分析 (28)5.3章节小结 (31)6 结论 (32)参考文献 (33)致谢 (34)附录 (35)附录1英文文献原文 (35)附录2中文翻译 (43)附录3前悬架左耳片CAD二维图 (49)附录4前悬架左立柱CAD二维图 (50)1绪论1.1本设计的目的与意义悬架,作为汽车连接车架与车桥的传力装置,是现代汽车上的重要总成之一。
预瞄主动悬架自抗扰控制
Dynamical Systems and Control 动力系统与控制, 2020, 9(4), 232-244 Published Online October 2020 in Hans. /journal/dsc https:///10.12677/dsc.2020.94023预瞄主动悬架自抗扰控制杨 国*,黄俊明#,杨 蓉广西大学机械工程学院,广西 南宁收稿日期:2020年10月2日;录用日期:2020年10月12日;发布日期:2020年10月27日摘 要预瞄主动悬架系统可获得车辆前方的路面不平度,这使悬架控制系统能够提前应对即将到来的路面激励。
为了使预瞄主动悬架控制系统能够适应不同的车速,同时考虑轮胎对路面的滤波效应,本文提出了一种预瞄主动悬架的控制方法。
该方法使用轮胎弹性滚子接触模型计算路面不平度的有效路形。
基于主动退让路面冲击或支撑车身的控制策略,将预瞄路面的有效路形作为控制器的控制参考信号。
以1/4车辆模型为被控对象设计自抗扰控制器,使悬架动行程根据预知的有效路形变化,从而实现预瞄控制。
分别在5~60 km/h 和5~100 km/h 的车速条件下进行了脉冲输入路面仿真和随机路面仿真。
结果表明,预瞄控制系统能明显减小车身垂向振动,在脉冲输入下的最高有效车速是30 km/h ,在随机输入下的最高有效车速是50 km/h 。
因此该预瞄控制方法能够适应不同的车速。
