| 摘 要： | 该文研究火炮系统的固有振动特性。求得了火炮系统固有振动的频率方程和振型函数的精确解析式。由此可见炮架的质量大小和分布对系统的固有振动影响很大。可根据该文导出的公式,通过调整炮架质量的大小、炮架质量的分布、炮口制退器的质量、支承条件等参数中的任一个、几个或全部参数,达到调整系统的固有振动,提高射击精度的目的。

| Abstract: | The natural vibration characteristics of the gun systemare studied in this paper. The exact analytic formulas of frequency e-quation and modal function descrbing the natural of the gun systemare obtained. It can be easily seen from the formulas that the effect ofmass quantity and distribute of the gun body on natural vibration ofthe system is great. Accoding to these formulas,we can regulate natu-ral vibration of the system and implove fire accuracy by regulatinganyone or all of the following quantities, such as the mass quantityand distribute of the gun body,mass of muzzle brake and conditions ofsupport. |
