摘要:
为研究不同模型和不同空气弹簧物理参数下车辆振动特性，基于热力模型和ADAMS空气弹簧非线性模型建立空气弹簧悬挂系统控制模型，并利用多体动力学仿真软件SIMPACK与 MATLAB/SIMULINK联合仿真平台建立包括空气弹簧系统的整车多体动力学模型。研究结果表明：热力模型较ADAMS模型更能准确模拟空气弹簧非线性动态特性；车辆低速运行时节流孔直径越小越有利于改善车辆垂向运行平稳性；车辆高速运行时节流孔直径太大或者太小都不利于改善车辆垂向运行平稳性；附加空气室体积越大越有利于改善车辆垂向平稳性，但是增大到一定程度继续增大对车辆垂向平稳性改善不是很明显。
Abstract:
Based on the thermal-mechanics model and the non-linear ADAMS air spring model, the control models of air spring suspension system were established. By using the co-simulation platform of the multi-body dynamics simulation software SIMPACK and MATLAB/SIMULINK, the vehicle multi-body dynamics model including the above-mentioned control models was established, and the vehicle vibration characteristics under different non-linear models and different physical parameters of air spring were studied. Analysis results showed that: the thermal-mechanics model could accurately simulate the non-linear dynamic characteristics of air spring; the orifices of small diameter could improve vehicle vertical running stability when running at low speed; too large or too small diameters were not conducive to improve vehicle vertical running stability during high-speed running; the auxiliary reservoirs of larger volume were help to the improvement of vehicle vertical running stability, but when the volume increased to a certain degree , the improvement was not very obvious.
