一种基于数值迭代的汽车起动机传动系统计算方法

以某型号汽车起动机为例,通过对驱动杠杆和单向器进行受力分析,完成了单向器推力表达式的推导。运用数值迭代法编程,绘制了单向器推力与单向器位置的关系曲线,并进行了实验验证。结果表明:仿真值与实验值的相对误差在允许范围之内,该方法可为工程上汽车起动机的设计提供一定参考。

Taking the starter of a certain type of automobile as an example,the force analysis of the driving lever and the one-way engine is carried out to complete the derivation of the thrust expression of the one-way engine.The relationship curve between thrust and position of unidirectional device is drawn by numerical iteration method and verified by experiment.The results show that the relative error between the simulation value and the experimental value is within the allowable range.
