摘要
通过对路面载荷谱幅值分布函数的拟合求解，依据疲劳等损伤原则，在提出当量频次概念的基础上，推导了计算汽车可靠性试验强化系数的数学模型。采用该方法分析计算一种试验场汽车可靠性试验强化系数，计算结果离散性小。
A mathematical model for calculating reliablity test intensifying coefficient of motor vehicle has been derived on the basis of equivalent frequency concept recommended,according to equal damage fatigue principle and by fitting solution of distribution function of road load spectrum amplitude on road surface.Analysis and calculation of reliability test intensifying coefficient for certain motor vehicle on proving ground are carried out by means of the model,of which small divergence of the calculation result has been gained.
