摘要

基于Pro/E、ADAMS、ANSYS及MATLAB多款软件联合仿真,建立了新型平行轴齿轮传动的采煤机截割部刚柔耦合模型,应用ADAMS/Vibration模块对其进行振动分析,通过观察系统的主要振型获知截割部的各激励源不会激发截割部系统发生共振,但观察系统第33阶振型,发现在截割部质心附近,出现了较大的扭转振动,为了提高该采煤机截割部的稳定性,对其传动系统进行了优化,结果表明:优化后截割部质心处x、y、z3个方向上的加速度响应幅值分别降低了74.2%、64.83%、7.02%,扭转振动明显减小,其他测试点振动幅值也都明显减少,此外壳体的自由模态和约束模态的变形幅值也得到明显改善,分别减少了95.9%和93.98%,优化效果显著。

Abstract

A virtual rigid-flex coupled prototyping of a new type shearer cutting unit is established based on the software of Pro/ENGINEER,ADAMS,ANSYS and MATLAB,and the forced vibration analysis of shearer cutting unit model is carried out based on the ADAMS/Vibration module,through the observation of main vibration mode of system find out that cutting of the excitation system does not inspire cutting part resonance occurs,but observation the system 33 order vibration mode,found near the center of mass in the shearer cutting,a larger torsional vibration is occuring,in order to improve the stability of coal winning machine shearer cutting,its transmission system is optimized,the results show that the centroid of the optimized shearer cutting x,y,zthree directions of the acceleration response amplitude is reduced by 74.2%,64.83% and 7.02%respectively,the torsional vibration decrease obviously,other test points are also significantly reduce the vibration amplitude,and the free modal and constraint modal of shell deformation amplitude have been improved significantly,decreased by 95.9% and 93.98% respectively,the optimization effect is remarkable.
