作为冲击压路机牵引主机主要减振环节之一的驾驶员座椅悬架系统,其振动特性不仅与整车的平顺性有密切的关系,而且还对驾驶员的身体产生直接的影响。针对冲击压路机牵引主机座椅悬架系统与车的刚性连接问题,分析振动对人体的危害以及对此问题进行研究的必要性,讨论引起座椅振动的主要原因,建立三自由度的座椅系统数学模型,并在MATLAB/Simulink中进行座椅动态特性仿真分析。分析表明:冲击压路机牵引主机座椅的舒适性尚需进一步改善,以减小振动对人体的伤害。
The driver’s seat suspension system which is one of the main shock absorption points of the impact roller traction main engine has not only the close relationship with the ride comfort of the vehicle, but also the driver’s body directly. In view of the rigid connection problem between the host seat suspension system and the vehicle by the impact roller, the hazard of the vibration to the human body and the necessity of studying the problem are analyzed. The main causes of the seat vibration are discussed, and the seat system with three degrees of freedom Mathematical model, and in the MATLAB / Simulink seat dynamic simulation analysis. The analysis shows that the comfort of the impact roller to tow the host seat needs to be further improved, so as to reduce the vibration damage to the human body.
