本文就混凝土输送泵车悬臂布料机构的振动机理作了某些探讨,并推导出实用的计算公式,最后通过分析找到了改善悬臂振动特性的某些途径。理论和实践都证明,悬臂布料机构在作业时,由于外扰力的作用会发生周期性振动,如果外扰力的频率与悬臂系统的某一固有频率接近,则悬臂系统将发生近共振,这种振动对于悬臂是十分有害的,这不仅造成悬臂前端大幅
In this paper, some discussion on the vibration mechanism of the cantilever fabric mechanism of the concrete pump truck is made, and a practical calculation formula is deduced. Finally, some ways to improve the cantilever vibration characteristics are found through analysis. Both theory and practice have shown that during operation, the cantilever fabric mechanism will periodically vibrate due to the effect of external disturbance. If the frequency of the external disturbance force is close to a certain natural frequency of the cantilever system, the cantilever system will experience near resonance. This kind of vibration is very harmful to the cantilever, which not only results in a large cantilever front
