摘要
为研究乘用车变速器载荷谱的采集与编制方法,以某型前置前驱乘用车变速器为例,根据不同路况,对该乘用车变速器的道路随机载荷谱进行了采集。根据变速器的载荷特性,采用幅值循环计数法对实车测得载荷的时间历程进行了统计处理,编制了乘用车变速器设计载荷谱,建立了乘用车变速器载荷谱采集与编制方法。该方法可为乘用车变速器设计提供准确的设计输入条件、以及为变速器疲劳寿命预测和台架疲劳寿命试验提供参考。
To study the sampling and compilation method of load spectrum of passenger car transmission,taking a certain type of front-engine,front-wheel-drive passenger car transmission as an example,according to different road conditions,the road random load of this passenger car transmission is collected.According to the characteristics of the load,the amplitude cycle counting method is employed to complete the statistical treatment for various time dependent loads tested in the road test.The design load spectrum of the passenger car transmission is compiled.The sampling and compilation method of load spectrum of the passenger car transmission is established.The method can provide accurate design input conditions for passenger car transmission,and provide a reference for accurate fatigue life prediction and fatigue test.
