摘要
将３９０内燃机配气机构简化为单质点振动系统，并对其进行弹性动力学分析，得出了实际气门运动规律．说明高速内燃机不宜采用圆弧凸轮．
In this paper the valve gear mechanism of internal combustion engine type 390 has been simplified as a vibration system with one degree of freedom. It is also analysed with the elastodynamic method and the actual motion of valve gear is obtained. It is proved that circular-arc eam is not suitable for high-speed internal combustion engine.
