该计算程序可以对无固定约束碰撞振动系统在激励力作用
下的系统响应进行计算，模拟系统动态响应，并自动判断颤振发生情
况，记录不同参数组合（阻尼比，质量比，恢复系数，间隙，频率比）
情况下系统的响应数据，输出发生颤振的参数组合数据。(The program can be used to study the impact force of a vibro impact system with no fixed constraint
The system response is calculated, the dynamic response of the system is simulated, and the occurrence of chatter is judged automatically
Different parameter combinations (damping ratio, mass ratio, recovery coefficient, clearance, frequency ratio) were recorded
In the case of the system response data, the output parameters of flutter data are output.)
