摘要
本文应用结构动力分析方法研究分析了汽车的动力结构模型,进行简化后以定速方式作用于桥梁,求得汽车对桥梁作用力的荷载模型。运用随机振动和非线性随机振动原理,进行了由于路面不平引起的汽车对桥梁作用的随机振动影响。根据以上分析研究编制了计算机分析程序。
Abstract In this paper,based on the principle of structural dynamics,the
dynamic model of the vehicle is investigated and simplified as a constant speed mode
to act upon the bridge,so that a load model of the vehicle on the bridge can be
obtained.The theory of random vibration and nonlinear random vibration were used
for computing the random vibration response of the vehicle on bridge due to uneven-
ness of the deck pavement.As a result,a computer program was worked out.
