针对机械产品寿命长价格昂贵,对这些机械产品做寿命试验十分困难。根据疲劳损伤累计原理,把实验的载荷、疲劳和实测工况的载荷、疲劳的关系建立起来,按照驱动桥主减速器的加速寿命试验推算出驱动桥主减速器在真实工况下的寿命。
Long life for mechanical products expensive, life-cycle test of these mechanical products is very difficult. According to the principle of cumulative fatigue damage, the relationship between the load and fatigue of the test and the load and fatigue of the actual working condition is established. The life of the final drive of the drive axle under real operating conditions is calculated according to the accelerated life test of the final drive of the drive axle.
