| description | The invention relates to a heat insulation tile array gap collision analysis method, and aims to solve the problem that heat insulation tiles collide with each other along with structural deformation, vibration and heat insulation tile array gap change when a heat insulation tile array on the surface of an aircraft is subjected to complex force, thermal load, vibration and noise effects during reentry. The heat insulation tile array gap collision analysis method and process based on the impulse method are established, the method and process can be applied to nonlinear dynamic response analysis of the heat insulation tile array and collision impact analysis between heat insulation tiles, gap collision of the heat insulation tile array can be quickly and accurately indicated, and impact force of gap collision of the heat insulation tiles can be evaluated.
本发明涉及一种隔热瓦阵列间隙碰撞分析方法，针对飞行器表面的隔热瓦阵列在再入时受到复杂的力、热载荷和振动、噪声作用，随结构变形、振动，隔热瓦阵列间隙变化，隔热瓦之间发生碰撞的问题，建立了一套基于冲量方法的隔热瓦阵列间隙碰撞分析方法和流程，可应用于隔热瓦阵列的非线性动力学响应分析及隔热瓦间的碰撞冲击分析，可以快速且准确 |
