上装振动水平对驾驶室平顺性的影响分析

摘要

The load on the military transport vehicles is large. Due to the poor driving conditions during the driving process, the movement of the upper part will have an impact on the ride comfort of the cab. Based on the establishment of the multi-body dynamic model of the vehicle, the paper analyzes the influence of the vibration level of the upper part on the ride comfort of the cab under different large loads. The results show that as the vibration level of the top coat decreases, the impact on the cab also reduces, which improves the ride comfort of the cab to a certain extent.%军用运输车辆上装载荷大,在行驶过程中由于行驶条件差,上装的运动会对驾驶室的平顺性产生影响.本文在建立整车多体动力学模型的基础上,对不同较大载荷下的上装振动水平对驾驶室平顺性的影响进行了分析.结果表明:随着上装振动水平的降低,其对驾驶室的影响也降低,在一定程度上提高了驾驶室平顺性.
