Structural Optimization of the Recoil Test Bench for Naval Gun Under Complex Loads
The recoil test bench was the support structure of the recoil test system of naval guns,and its rigidity would directly affect the test accuracy and test safety.In order to further improve the rigid strength of the bench,the structural optimization research under the composite action of normal opera-tion and swing load was carried out.Through the establishment of the dynamic analysis model,the load change law of the recoil and counter-recoil motion process was obtained,the stress and deformation un-der the maximum load were obtained by finite element analysis,the sensitivity analysis and experimen-tal design of the thickness parameters of the test bench were carried out,the response surface of the thickness of the key plate beam and the maximum stress and deformation was established according to the Kriging model,and the optimal parameter scheme was predicted by the multi-objective optimization method and the optimization effect was verified.The results show that the cross beam 2 on the bench and the bottom of the front bearing seat of the counter-recoil meshanism are prone to damage.Adjus-ting the thickness of the upper cross beam 2,the upper diagonal rib plate and the upper frame can ef-fectively improve the rigidity of the bench.
