摘要/Abstract

摘要： 为了研究自行火炮结构动态响应规律，以轮式和履带式火炮为研究对象进行了全炮模态测试，得到了全炮的固有频率及其相应模态。通过对轮式与履带式自行火炮系统振型分析，可以得到如下结论：对于轮式自行火炮和履带式自行火炮，在低频范围内从低到高其固有振型依次为全炮俯仰、平动和横滚；对于本文所选试验对象，履带式自行火炮全系统俯仰、平动和横滚固有振型对应的固有频率分别大于轮式自行火炮；对于轮式自行火炮模态测试采用传统试验模态分析方法和工作模态分析方法，均可以得到满意的试验结果，工作模态分析方法较为适合履带式自行火炮模态测试。

Abstract: To investigate the structural dynamic rules of the self-propelled gun, the modal test experiments were carried out and the natural frequencies and the modes were obtained of the wheeled and tracked self-propelled guns. Analyzed their natural modes, it is concluded that, for both self-propelled guns, the natural modes from low to high frequency are pitch, fluctuation and roll; the natural frequencies in three modes of the tracked self-propelled gun are higher than those of the wheeled self-propelled gun; both operational and traditional modal analysis methods are suitable for the modal test of the wheeled self-propelled gun, and the operational modal analysis method is suitable for the modal test of the tracked self-propelled gun.

Key words: applied mechanics, self-propelled gun, experimental modal analysis, natural frequencies, natural modes
