Particle damping technology is a passive vibration and noise reduction technology,which has been successfully applied in many fields.Taking a cantilever pipe with the particle damping as the research object,the vibration damping ability of the particle damper of the cantilever pipe was verified by the test method and simulation.The influence of different parameters of the particle damping on the vibration reduction effect of the cantilever pipe was analyzed through the simulation.The results show that the particle damping has a significant vibration reduction effect for the cantilever pipe,and the results of testing and simulation are in good agreement,which verifies the reliability of the algorithm.This study provides an important reference for the design of vibration damping performance of cantilever pipes.
