摘要
根据排气门的运动规律及相应的受力情况,运用动力学分析方法建立了配气机构单质量模型及动力学微分方程。通过编程计算,获得某发动机排气门的气门升程、速度和加速度曲线。由分析结果可以看到:该动力学模型能够正确反映配气机构的运动规律和动力学特性,简单实用,便于理论分析。
Based on the motion law and force conditions of exhaust valve of an engine,a dynamic analysis method is used to obtain the single-mass dynamic model of the valve train with its dynamic differential equations.The valve＇s displacement,velocity and acceleration curve are gotten by computer codes.The results show that this model can correctly reflect the motion law and dynamic characteristics of the valve train,is simple and practical and convenient for theoretical analysis.
