摘　　要：正确认识动力刚化问题,对深入研究航天器动力学和合理建立柔体动力学的数值计算模型意义重大.应用非惯性坐标系中的力学问题的理论来研究动力刚化问题,给出两类研究动力刚化问题的计算模型,明确了动力刚化问题的物理意义,探索了正确处理零次建模的途径.这样处理动力刚化问题,表现出与其他学者的研究有实质性的差异.Correct understanding of the dynamic stiffening problem is signality for further researching spacecraft dynamics and establishing a rational numerical model of flexible body dynamics.The dynamic stiffening problem was studied using the theory of a mechanical problem in a non-inertial coordinate system.Two kinds of numerical models for the dynamic stiffening problem were established.The physical meaning of the dynamic stiffening problem was clarified.The approach of correct zero-order modeling was explored.There is a substantive difference between the research of this paper and the research of other scholars.
