Abstract
In order to improve the detection ability of the spring impactor calibration device and reduce the energy loss in the collision process, the impact structure optimization design method based on the response surface method is proposed with the optimization objective of minimizing the deformation of the impact structure and the mass of the components. Optimization results show that the relationship between the impact structure size and the maximum deformation is non-linear, and the relationship with the mass is partially linear. The impact structure of the pendulum meets the strength requirements while the maximum deformation is reduced by 24.59% and the mass is reduced by 12.97%, taking into account the requirements of high strength and light weight, which proves the effectiveness of the proposed impact end optimization method based on response surface curve fitting and multi-objective variable optimization. The response surface curve optimization method improves the optimization efficiency while ensuring the accuracy, and provides a new path for the optimization of the spring impactor calibration device.
