活塞环自由型线计算方法的比较

Comparison of Calculation Methods on Freedom Molded Lines of Piston Ring

论述活塞环径向压力分布函数的一般形式 ,归纳、总结由径向压力分布求解自由状态型线的方法 ,对各种计算方法进行了分析比较 .实际计算结果表明 ,各种计算方法之间误差较大 ,实际应用中采用能量法较宜 .

A generality format of piston ring radial pressure force distribution function was discussed. The methods by known radial pressure force distribution function to solve freedom molded lines were summed. Each calculation method was analysed and compared by real examples. From the results of calculations, there were big errors among each calculation method. In real uses, the energy method should be prior to be considered.
