中文摘要:为同时改善车辆的道路友好性和平顺性,达到缓解驾驶疲劳、延长道路使用寿命的目的,提出一种基于正交试验的多轴重型货车悬架系统改进天棚控制策略。依据车辆动力学原理和虚拟样机技术,采用ADAMS构建四轴重型货车〖CD*2〗路面系统的高精度仿真模型,通过实车平顺性试验验证其正确性;选择合理匹配的空气悬架替换驱动轴平衡悬架,完成车辆道路友好性、平顺性的初步优化;基于ADAMS/Matlab联合仿真对四轴重型货车虚拟样机的悬架系统分别进行半主动、主动改进天棚控制,并以控制参数为变量设计正交试验,通过极差、方差分析确定使车辆道路友好性、平顺性综合最优的控制参数。仿真结果表明,主动、半主动改进天棚控制的货车道路友好性相当,前者的平顺性优于后者,而且该控制策略对路面等级的变化具有较强的鲁棒性。

Abstract:A modified skyhook damping (MSD) control strategy for multi-axial heavy truck suspension system based on orthogonal test was put forward. It could improve the road friendliness and ride comfort of the truck simultaneously, as a consequence, ride fatigue was alleviated and road life was prolonged. A multi-DOF model of four-axial heavy truck-road system was developed in ADAMS based on vehicle dynamics and functional virtual prototype (FVP), and the model was validated through a ride comfort test. In order to improve the truck performance preliminarily, proper air suspensions were chosen to replace the tandem suspension on the driving axles. Subsequently, semi-active, active MSD control were applied to the whole suspension system respectively using co-simulation of ADAMS and Matlab, and control parameters which ensured best integrated performance of the truck were chosen based on range analysis and variance analysis of orthogonal test. The simulation results indicated that ride comfort of the active MSD control truck was superior to the semi-active MSD control truck, however, the road friendliness were comparable. In addition, MSD control had a strong robustness to road level.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
