本文分析了汽车在不平整路面(波浪路面)上行驶时的纵向角振动和竖向振动问题。在研究竖向振动时,把纵向角振动的影响考虑进去,给出了振动方程的解。对于汽车振动时,车轮给予路面的附加动荷载的计算问题着重进行了讨论,并研制了电子称测定车辆以不同速度通过不同的不平整时,车轮对路面作用的动荷载值。试验结果和计算值的一致性,证明了本文分析方法的正确性。
This paper analyzes the longitudinal vibration and the vertical vibration when the car is driving on an uneven road surface (wavy road surface). When studying the vertical vibration, the influence of the longitudinal vibration is taken into account, and the solution of the vibration equation is given. The calculation of the additional dynamic load given to the road surface by the wheel is mainly discussed when the vehicle is vibrating. The dynamic load value of the wheel on the road surface when the vehicle passes the different irregularities by different speeds is developed. The consistency between the experimental results and the calculated values proves the correctness of the analysis method in this paper.
