EXPERIMENTAL MODAL ANALYSIS AND NUMERICAL SIMULATION OF THE ARTILLERY RECOILING PARTS}
火炮试验架动态特性试验模态及数值分析

The dynamic behaviors of the artillery recoiling parts have an important effect on the measurement accuracy of the artillery launch test and the evaluation of the artillery performance. In this paper, we determine the optimum response points and driving points of the structure on the basis of the FEA model, then obtain the natural frequencies and modes of the structure with the optimized model of the experimental modal analysis. The test results show that the FEA analysis can improve the efficiency of the experimental modal analysis and the dynamic performance of the structure could be obtained with good accuracy.
