摩托车单缸发动机曲柄连杆机构振源分析方法对比(1)

A Comparison of Analytical Methods for the Vibration Source of Single-cylinder Engine Crankshaft-connecting Rod Mechanism of Motorcycles (1)

分别采用矩阵法和实体模型仿真法对DY90型发动机的曲柄连杆总成进行动力学仿真,并将结果与传统的惯性力激振理论作对比,通过对进一步实验所得数据进行分析以验证各仿真方法的合理性。

The crankshaft-connecting rod mechanism assembly of DY90 engine has been dynamically emulated by applying the matrix method and physical model emulation method. And a comparison between the emulated result and that gained based on the inertia force theory is made. The further tests have been conducted for the purpose of verifying the rationality of all the emulation methods.
