摘要
采用脉冲锤击法对某厂生产的凿岩台车伸缩臂进行了试验模态分析,获得了两种工况下0～300Hz以内凿岩台车伸缩臂的各阶模态参数,并对各阶模态振型进行了分析,为进行结构的优化设计提供依据。
The paper makes test modal analysis to the telescopic boom of certain brand rockdrilling rig by pulse hammering approach, acquired the modal parameters at each stageof the telescopic boom of the rock drilling rig between 0 to 300 Hz under two differentwork condition, and makes analysis to vibration model of each stage, which offersreference for optimization design of structure.
