摘要:
为研究不同转速下放电加工电流对电动汽车驱动电机寿命的影响,基于电动汽车驱动系统 的轴电压模型,以弹性流体润滑理论分析了载荷和车速对轴承各钢球的油膜厚度和赫兹接触面积 的影响,以 6006 球轴承为例,计算了不同载荷和车速下轴承的等效电容值,建立了轴承放电加工电 流的仿真分析模型,利用电流和赫兹接触面积的比值给出了轴电流的表面电流密度,进而对轴承电 气寿命进行解析计算,最后,给出了电气和机械老化应力同时作用时轴承寿命的简单分析方法。
Abstract:
To study the influence of electric discharge machining ( EDM) current on electric vehicles ( EVs) drive motor lifetime at different speeds,the elastic fluid lubrication theory was used to analyze the effects of load and speed on oil film thickness and hertz contact area of each ball based on shift voltage model of EVs drive system. In 6006 ball bearing case,the values of bearing equivalent capacitances were calculated at different loads and speeds. A simulation model was established to analyze the EDM current, and bearing surface current density was given by the ratio of current and hertz contact area. Analytical cal-culation of the bearing electrical lifetime was conducted. At last,a simple life analysis method of bearing was given with simutaneous action of electrical and mechanical stress.
