摘　　要：为了研究掘进机的振动特性,采用拉格朗日法建立了随机激励下的横向和纵向运动方程。通过使用虚拟激励方法通过随机激励生成随机振荡,可以进行数学计算。它模拟了掘进机的水平和垂直振动响应,并使用Matlab汇编语言解决了寻找掘进机三阶系统的固有频率和模式以及响应特性的问题。In order to study the vibration characteristics of roadheader,the transverse and longitudinal motion equations under random excitation are established by Lagrange method.By using the virtual excitation method,random oscillation is generated by random excitation,and mathematical calculation can be carried out.It simulates the horizontal and vertical vibration response of roadheader,and solves the problem of finding the natural frequency,mode and response characteristics of the third-order system of roadheader by using Matlab assembly language.
