为减小炮口振动,提高射击精度,提出了采用“吸振”措施消减身管炮口振动的思想。应用假设振型法,对炮口有无吸振器情形下炮口的响应进行了一般分析,并考虑了后座复进运动,建立了吸振的数学模型,初步证实采用吸振是可以抑制炮口振动的。模拟射击实验证明,在炮口处安装吸振器后,其振动幅值消减50 % 。理论研究还表明,虽然火炮身管振动的频率成分丰富,但其主要成分为一阶频率,吸振器的设计必须依此进行。
In order to reduce the muzzle vibration and improve the shooting accuracy, the idea of adopting “vibration absorption” to reduce the muzzle vibration of the barrel was put forward. Applying the hypothetical model method, the muzzle response under the muzzle presence or absence of a shock absorber is analyzed. The recoil movement of the rear seat is considered and a mathematical model of vibration absorption is established. It is initially proved that vibration suppression can suppress the muzzle vibration of. Simulated shooting experiments show that the installation of shock absorber at the muzzle, the vibration amplitude reduction of 50%. The theoretical study also shows that although the frequency of the vibration of the barrel is rich, the main component of the gun is the first-order frequency. The design of the vibration absorber must be carried out accordingly.
