本章论述了用脉冲激振法激励某型泥浆泵机架体,通过模态试验和模态分析,获得了机架体前9阶模态参数。它为更合理地改进产品结构和进行动态优化设计,提供了技术数据。
In this chapter, we discuss the excitation of a certain type of mud pump frame by pulse excitation method. Through the modal test and modal analysis, the first nine order modal parameters of the frame body are obtained. It provides technical data for more rational product structure improvement and dynamic optimization of design.
