Analysis Of Separation Dynamics For Fairing

This article deals with dynamics analysis of the course that a fairing is separated. Firstly, the fairing is predigested a pure rigid body to be analyzed in the method of consistent mass, getting the kinematical and dynamical response of the fairing. Moreover, the model theory for dynamics of flexible multibody systems on plane and in space is studied, establishing dynamics models of dynamics of flexible multibody systems respectively on plane and in space. With general symbolic computation software (MATHEMATICA), the important consistent mass matrix of dimensional triangle plank element and its differential coefficient are induced. At the same time, general forces(QV) related to velocity binomial in dynamics dominate equations are also induced. Correctness and validity of symbolic computation are tested by examples. The steps of analyzing dynamics of flexible multibody systems are further discussed, then dynamics analysis and calculation are dealt with the dome model established in this article.Various methods, with which to solve control equations of dynamics of flexible multibody systems, are discussed. Moreover, the control equations of dynamics for dimensional plank element are solved and analyzed by using Newmark method. Correctness and validity of dynamical theory and symbolic computation are tested in the course of dome casting which is established in the method of dynamics of flexible multibody systems that the rotating axes is changeless.
