摘　　要：后坐试验台架是舰炮后坐试验系统的支撑结构,其刚强度会直接影响测试准确性和试验安全性。为了进一步提高台架的刚强度,开展了正常工作与摇摆载荷复合作用下的结构优化研究。通过动力学分析模型的建立,获得后坐与复进运动过程的载荷变化规律,采用有限元分析得到受最大载荷时的应力与变形,对试验台架的厚度参数进行了灵敏度分析和试验设计,根据Kriging模型建立了关键板梁厚度同最大应力和变形的响应曲面,结合多目标优化法预测最优参数方案并验证了优化效果。结果表明:台架上横梁2与复进机前承座底部易发生损坏;调整上横梁2、上斜肋板及上纵板的厚度可有效提高台架刚强度。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 operation 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 under the maximum load were obtained by finite element analysis,the sensitivity analysis and experimental 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.Adjusting the thickness of the upper cross beam 2,the upper diagonal rib plate and the upper frame can effectively improve the rigidity of the bench.
