| 摘 要： | 为了评价复合材料身管动态特性，在模态分析和阻尼分析的基础上，采用模态叠加动力学有限元计算方法，
对复合材料身管的强迫响应特性进行分析，计算获得复合材料身管的炮口振动情况，并与相同口径的金属身管炮口
响应情况进行比较。结果表明，复合材料身管炮口响应小于金属身管炮口响应，复合材料身管具有更好的动态特性
。

| Abstract: | In order to evaluate the dynamic property of composite material barrel,the forced response analysis is conducted by using mode superposition method on the basis of modal analysis and damping analysis. The muzzle vibration status of the composite material barrel is obtained and compared with which of the steel barrel. The results show that the response amplitude and frequency of composite material barrel is less than the response of steel barrel. The dynamic property of the composite material barrel is much ... |
