中文摘要:在考虑簧载质量振动的情况下以轿车转向系与前悬架的耦合非线性振动系统为研究对象,应用集中参数法建立髙维耦合系统的7自由度非线性动力模型,模型中综合考虑轮胎的非线性侧偏特性,悬架的非线性弹簧-阻尼力以及转向系连杆的弹性作用。通过数值仿真研究,揭示了车轮存在失衡量时耦合系统的动态特性和转向系参数、前悬架参数对整车摆振的影响,明确了转向系振动与前悬架振动的相互作用关系,为耦合动力系统的动态设计与综合动力学控制提供了理论依据。

Abstract:The combination of vehicle steering system and front suspension system is a dynamic coupled system. In allusion to coupled nonlinear vibration system of a car steering system and front suspension, a high dimension coupled 7-DOF. nonlinear vibration model was constructed using a concentrated parameters method. The nonlinear lateral force of tires, the nonlinear elastic force and damping force of the front suspension and the elastic effect of steering system connective poles were taken into account during the modeling. The dynamic characteristics of the coupled system and the parameter effects of automotive steering and front suspension were illustrated by numerical analysis when the mass unbalance existed in the front wheel, and the vibration relation between the steering system and front suspension was revealed. Research results can provide the theoretical support for dynamic design and synthetical dynamic control of coupled nonlinear vibration system.

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.
