Numerical simulation and impact test of hand-held vacuum cleaner dust collector

Abstract

In order to study the dynamic response of the dust collector in the process of free fall, the author used the HYPERMESH/LS-DYNA software to simulate the fall-ing process; set up a drop test platform and used a high-speed camera to record the collision process, and used sensors to obtain parameters such as impact force and acceleration during the fall. Finally, the experimental results are compared with the simulation results. The results show that: (1) The numerical simulation shows the collision process of the dust collector very well, which is very con-sistent with the part disengagement and structural deformation that occurred in the experiment. (2) The impact force and acceleration values obtained by simulation and experiment are relatively close, which also verifies the reliability of the simu-lation. This study evaluated the impact resistance of the dust bucket, which con-tributed to the reduction of product development costs and subsequent structural improvements.
