Based on the on-site situation of the caving of the MEMS inertial sensor protection device in the field blasting of Qidashan, this paper analyzes and studies the dynamic characteristics of the caving impact process and simulates and emulates the MEMS inertial sensor protection device using the finite element software Solidworks/Simulation, and derives the stress and strain clouds of the structural components of the MEMS inertial sensor protection device in the process of collapse impact, as well as the measurement data of the acceleration trajectory of different structural components as a function of time. On the basis of the simulation and emulation results, the system analyzes the structural components of the MEMS inertial sensor protection device affected by caving impact, thus providing an important reference and basis for the research on the performance of the MEMS inertial sensor protection device against caving and impact during mine blasting.
