船舶扭振计算的例程，船的轴系较复杂，所以大多数例子都是关于船舶的！-an example of ship torsional vibration

根据高等转子动力学内容，编程计算转子-轴系固有扭振频率代码，每一步均配有相应的注释说明。-According to the higher rotor dynamic content, programming calculation of rotor shafting torsional vibration inherent frequency code, each step with the corresponding notes.

采用MATLAB编写的，斜齿轮时变啮合刚度计算程序。原理参见李瑰贤的《宽斜齿轮副啮合刚度计算及扭振特性的研究》。-program to calculate the time-varing menshing stiffness of helical gear.

对于主泵、汽轮机等扭振分析所用到的固有频率计算及振型分析-For the calculation of natural frequencies and modal analysis of torsional vibration analysis used by the main pumps, turbines, etc.
