摘要

本文提出了轴对称导弹弹体在复杂条件作用下的动力学模型的建立方法,并对导弹弹体的振动特性及柔性变形对弹道的影响进行了研究。首先,依据传统的导弹飞行力学理论,分别建立了控制力、气动力耦合作用下的刚性导弹和柔性导弹弹体动力学模型;然后,在铁木辛柯梁弯曲理论的基础上,推导出控制力、气动力和弹性振动耦合作用下的柔性弹体变形方程;最后根据上述模型,分析了柔性变形对弹道参数的影响.

Abstract

A method of establishing dynamical models of axial symmetry missiles with complicated dynamical coupling was presented in this paper. The effects of vibration characteristics and flexibility deformation on the trajectory of flexible missiles were considered. First, according to traditional flight dynamics theory, the approach of establishing dynamical models of rigid missiles and flexible missiles with control force and aerodynamical force coupling was proposed. Second, the deformation equation of flexible missiles with control force, aerodynamical force and vibration coupling was derived based on Timoshenko beam theory. Finally, the effect of the flexible deformation of missiles to ballistic parameters was analyzed.
