舰炮振动分析的多体系统有限元传递矩阵法

Finite Element Transfer Matrix Method of Multibody System for Naval Gun Vibration Analysis

为保证舰炮具有良好的动态性能和射击精度,就必须使其振动频率合理分布。建立了多体系统有限元传递矩阵法,从理论、计算、试验三方面研究了舰炮固有振动特性,进行了某舰炮振动特性计算和舰炮模态试验。计算结果与试验结果吻合良好。

To ensure good firing precision and good dynamical performance,naval gun vibration frequency must be reasonably distributed.Finite element transfer matrix method of multibody system was established.Natural vibration characteristic of naval gun was studied from the aspects of theory,calculation and test.Vibration characteristic was calculated by using finite element transfer matrix method of multibody system and modal test was completed for a certain naval gun.The modal test results are in compliance with the calculated results.
