悬挂缸倾斜的连通式油气悬架刚度特性研究
|
摘要
油气悬挂缸的安装角度对连通式油气悬架刚度特性具有重要影响,从悬挂缸安装角度出发,推导了连通式油气悬架系统的理论刚度计算公式,并利用MATLAB建立了其模型。利用ADAMS和AMESim建立了相应的联合仿真验证模型,并搭建了实验测试平台。针对连通式油气悬架系统进行了侧倾刚度和垂直刚度的理论计算、仿真和实验测试,通过理论计算、仿真和实验测试结果的对比分析,证明了理论计算公式的正确性。在此基础上,分析了悬挂缸不同安装角度的侧倾和垂直刚度特性。分析结果表明:随着悬挂缸安装角度的增大,连通式油气悬架的侧倾刚度减小,侧倾刚度的非线性特性变弱,其垂向刚度增大。
The installation angle of hydro-pneumatic suspension cylinders has important influence on the stiffness characteristics of the interconnected hydro-pneumatic suspension system. Based on the installation angle of hydro-pneumatic suspension cylinders, the theoretical stiffness calculation formula of the interconnected hydro-pneumatic suspension system was deduced and its model was established by MATLAB software. The ADAMS and AMESim software were used to establish the corresponding co-simulation validation model, and an experimental test platform was built. The theoretical calculation, simulation and experimental tests of roll stiffness and vertical stiffness were carried out for the interconnected hydro-pneumatic suspension system. The comparison of the results from the theoretical calculation, simulation and experiment indicates that they had high consistency. It was verified the correctness of the theoretical formula. Moreover, the characteristics of the roll stiffness and vertical stiffness of different installation angles of hydro-pneumatic suspension cylinders were analyzed.The analysis results show that with the increasing of the installation angle of hydro-pneumatic suspension cylinders, the tendency of the roll stiffness of the suspension decreases,non-linear characteristics of roll stiffness become weaker,and the vertical stiffness of the interconnected hydro-pneumatic suspension increases.
