摘要
逐步积分法可以用来解决非线性扭转振动问题。本文结合内燃机轴系的特点,对各类逐步积分算法进行分析,指出隐式的纽马克法和威尔逊法是解决扭振问题的最佳算法。文中并行采用这两种算法编制了内燃机轴系非线性扭转振动通用计算程序,并给出两个算例。
In this paper, some kinds of the schemes are investigated combing with the characteristics of engine shafting. Analysis result shows that the Newmard's method and the wilsion's method are more suitable for solving torsional vibration problems . A general computing programme is developed using both methods mentioned above, and two examples are presented.
