Optimization design and analysis of transmission device for impact simulation test of special machinery

The impact simulation test system for special mechanical parts is designed to simulate the motion and impact conditions of special mechanical parts under actual working conditions. This paper takes the whole machinery as the research object, and optimizes the design and analysis of a certain type of special machinery parts impact simulation test transmission device, with the goal of improving the motion characteristics of the transmission mechanism and reducing the load of the motor, optimizes the transmission mechanism based on the particle swarm algorithm and the variable density method, and carries out the strength checking and movement reliability analysis in ABAQUS and ADAMS . The simulation results show that the error between the impact impulse applied by the designed impact simulation test transmission and that driven by gunpowder gas is 8.71%, and the velocity error is within 5%. The cam mass is reduced by about 13.7% after topology optimisation, its rotational inertia is reduced by 11.8%, and the maximum torque of the drive shaft is reduced by about 8.4%. The optimised design of the impact simulation test drive is feasible and can provide an effective technical means for the subsequent structural optimisation design and impact detection of the tested special machinery.
