Simulation technology of impact resistance performance of naval air conditioning equipment
To verify the impact resistance performance of a naval air conditioning,according to the structure and basic principle of the bench device of the pendulum type medium weight impact test,the finite element model of the bench is built using Ansys software.Based on the explicit dynamics and the basic theories of contact collision analysis,the impact load generation process is simulated and analyzed in finite element software LS-DYNA.The simulation result is compared with the experimental test data,and the model is verified.The impact resistance performance of the naval air conditioning heat exchanger is analyzed using the finite element model of the impact test bench.The complete response process of the equipment under medium weight impact load is obtained.The results show that the overall impact resistance performance of the naval air conditioning heat exchanger needs to be improved.
