摘要:
基于有限段思想建立身管多体动力学模型,将身管离散为有限个刚性段,每两段质心之间用一个无质量的梁连接,根据Timoshenko梁理论确定质心间的力和力矩,考虑身管截面沿轴线的变化,采用第一类Lagrange方程推导了身管的多刚体动力学方程,并给出相应的算例,结果表明:采用身管多体动力学模型可较精确地计算火炮的炮口扰动和描述身管的振动。
Abstract:
B ased on the idea of finite segments, themu lt-i bodymodel o f a barre l is estab lished as th is: A barre l is div ided into som e rig id segments, w h ich are linked by massless beams at the center of mass. Force andmom ent are ca lculated based on the beam theory of T imoshenko. The variation o f the barre l. s sect ion along the ax is is considered. Mu lt-i body dynam ic equations of a barre l are formulated by app ly ing the Lagrange equations o f the f irst k ind. The dynam ic analysis of a certain gun is g iven as an example. The resu lts indicate that themu lt-i bodymodel can be used to calcu late themuzzle of a barre l and describe the v ibrat ion of the barrel.
