面向汽车燃油泵的凸轮轴系分析研究

Analysis of Cam System for Car Fuel Pump

针对汽车中的高压燃油泵和凸轮,建立一整套模拟高压供油系统的凸轮轴系。为延长凸轮轴系的使用寿命和提高高压燃油泵的工作精度,提出避免在实际加工制造中造成重要误差的方法。应用Solid Works中的Simulation插件对轴系进行应力应变分析,选取合适的轴尺寸和材料。结果表明,所设计的轴系符合要求,满足高压燃油泵正常工作时的所需条件,且可靠实用,具有较长的寿命。

For automotive high-pressure fuel pump and cam,establish a set of camshaft system for simulated high-pressure fuel system.To extend the service life of the camshaft system and improve the working accuracy of the high-pressure fuel pump,this paper presents methods to avoid significant errors in the actual manufacturing.Apply Simulation of Solid Works to analyze shaft＇s stress and select the right size and material of shaft.
