摘要
针对井下分级破碎机分体式机架结构稳定性的问题,使用ANSYS Workbench对分体式机架进行模态分析,得到分体式机架的振型分布。从机架各阶模态下的固有频率和振型得出机架的主要振动形式,并对分体式机架的设计进行评价,可以看出:机架的摆动和扭转是其结构动态特性的主要表现形式,机架的固有频率对分体位置的振动没有明显影响。
An ANSYS Workbench-based modal analysis is made on the stability of the underground sizing crusher,s split-type frame assembly, and through which the distribution of vibration mode, as well as the principal vibration mode of the crusher frame are made known according to the inherent vibration frequencies and vibration patterns of different modal orders. And finally, an assessment is made on the design of the split-type crusher frame. As evidenced through analysis, the dynamic characteristics of the crusher frame manifest mainly in the form of wobbling and twisting motion, and no significant effect of the inherent frequency of the frame on the vibration of the frame,s segmented points can be observed.
