Simulation and Experiment of Hand-held Vacuum Cleaner Host Drop

Abstract: Based on Hypermesh /LS-dyna, the drop simulation of the handheld vacuum cleaner host was carried out to simulate the phenomenon of part disengagement and structural deformation that may occur during the fall. A drop impact test bench containing three modules including posture control, data acquisition and motion analysis was built to test the impact resistance of the host prototype. The numerical simulation vividly shows the collision process of the handheld vacuum cleaner host, which is consistent with the phenomenon of part disengagement and structural deformation that occurred in the drop impact test. The impact force and acceleration peak values obtained by simulation and experiment are relatively close, which also verifies the reliability of the simulation. The impact resistance of the host was evaluated in this study, which helps reduce product development costs.
