| 1 | 捷联惯导减振系统的耦合振动研究显示文摘目的研究耦合振动对捷联减振系统的影响。方法建立惯导减振系统动力学模型,并在有限元分析软件中对系统进行模态分析,然后通过扫频试验对比有无偏心情况下的响应。结果安装中心与弹性中心的不重合是导致线振动和角振动耦合的原因。结论对工程中减振器的安装提出了3个方面的要求,尽量保证弹性主轴与惯性主轴重合,避免偏心;增大安装半径,提高角振动与线振动频率比值;增加轴套等定位设备,增加寿命和精度。 | 李晓波 吴斌 董程 李宝利 | 2014 | 装备环境工程2014，11，2： | 10 |
| 2 | Comparison of two suspension control strategies for multi-axle heavy truck显示文摘Two simple and effective control strategies for a multi-axle heavy truck, modified skyhook damping (MSD) control and proportional-integration-derivative (PID) control, were implemented into functional virtual prototype (FVP) model and compared in terms of road friendliness and ride comfort. A four-axle heavy truck-road coupling system model was established using FVP technology and validated through a ride comfort test. Then appropriate passive air suspensions were chosen to replace the rear tandem suspensions of the original truck model for preliminary optimization. The mechanical properties and time lag of dampers were taken into account in simulations of MSD and PID semi-active dampers implemented using MATLAB/Simulink. Through co-simulations with Adams and MATLAB, the effects of semi-active MSD and PID control were analyzed and compared, and control parameters which afforded the best comprehensive performance for each control strategy were chosen. Simulation results indicate that compared with the passive air suspension truck, semi-active MSD control improves both ride comfort and road-friendliness markedly, with optimization ratios of RMS vertical acceleration and RMS tyre force ranging from 10.1% to 44.8%. However, semi-active PID control only reduces vertical vibration of the driver's seat by 11.1%, 11.1% and 10.9% on A, B and C level roads respectively. Both strategies are robust to the variation of road level. | 陈一锴 何杰 M.King 冯忠祥 张卫华 | 2013 | Journal of Central South University2013，20，2： | 5 |
| 3 | Robust control for active suspension system under steering condition显示文摘To minimize the auto body's posture change caused by steering and uneven road, and improve the vehicle's riding comfort and handling stability, this paper presents an H∞ robust controller of the active suspension system, which considers the effects of different steering conditions on its dynamic performance. The vehicle's vibration in the yaw, roll, pitch and vertical direction and the suspension's dynamic deflection in the steering process are taken into account for the designed H∞ robust controller, and it introduces the frequency weight function to improve the riding comfort in the specific sensitive frequency bands to human body. The proposed robust controller is testified through simulation and steering wheel angle step test. The results show that the active suspension with the designed robust controller can enhance the anti-roll capability of the vehicle, inhibit the changes of the body, and improve the riding comfort of the vehicle under steering condition. The results of this study can provide certain theoretical basis for the research and application of active suspension system. | WANG ChunYan DENG Ke ZHAO WanZhong ZHOU Guan LI XueSong | 2017 | Science China(Technological Sciences)2017，60，2： | 3 |
| 4 | 检查井及井周路面病害影响下的行车舒适性显示文摘为评价车辆经过检查井及井周路面时的行车舒适性,在井周路面平整度状况调查及分析的基础上,建立人-车-井盖耦合振动1/2车辆模型,以加权加速度均方根值为评价指标,以ISO 2631-1-1997为评价标准,分析驾驶员垂向加速度和加权加速度均方根值的变化规律及影响因素,对车辆经过检查井及井周路面时的行车舒适性进行评价,并通过加速度现场测试试验验证.结果表明:井周路面行驶质量远差于一般路面;车辆经过井盖时驾驶员加速度达到最大,为4.72 m/s^(2),加权加速度均方根值为1.281 m/s^(2),行车舒适性评价为“非常不舒适”;坡度变化率、井周路面病害造成的高差和井盖沉陷量对行车舒适性的影响较大;加速度最大值与加权加速度均方根值理论计算结果与现场测试结果相比,误差均在合理范围内,理论分析结果可靠.可见,提出的理论分析方法可用于车辆经过检查井及井周路面时的行车舒适性评价,以合理确定检查井及井周路面养护时机及制定养护策略. | 赵全满 王鑫均 井硕 刘继法 赵品晖 胡文军 | 2022 | 北京交通大学学报2022，46，3： | 2 |
| 5 | 检查井及井周路面影响下的车辆荷载动态特性显示文摘为分析车辆经过检查井及井周路面时的车辆荷载动态特性,采用井周路面病害调查的方法确定了井周路面病害类型及范围;考虑井盖的变形和振动,建立了车-井盖耦合多自由度振动模型;分析了车辆荷载冲击系数随时间变化的规律及影响因素。研究结果表明:在检查井及井周路面平整度激励作用下,车辆由井周路面驶入正常路面时车辆荷载冲击系数达到最大值,此时车辆荷载为静载的1.35倍;各因素对车辆荷载动态特性影响程度从大到小排序为:井周路面病害导致的高差>检查井沉陷量>坡度变化率>行车速度>井盖刚度系数。由此可见,车辆经过检查井及井周路面时路面的平整度大小是(井周路面病害导致的高差、检查井沉陷量和坡度变化率)导致车辆荷载冲击效应是否显著的原因,也是井周路面频频破坏的主要因素之一。 | 赵全满 王鑫均 卢晓锦 刘继法 胡文军 | 2023 | 重庆交通大学学报(自然科学版)2023，42，7： | 0 |
