完整非保守系统的积分不变量及其在时间有限元法中的应用
Integral Invariants of Holonomic Nonconservative Systems and Their Applications in Time-Domain Finite Elemens Method
【摘要】 本文首先导出完整非保守系统的Poincare'-Cartan型积分不变量及Poincare'通用积分不变量。然后以积分不变量为工具,导出了时间有限元的计算格式,可以求解动力响应问题。
【Abstract】 in this paper the Poincare and Poincare-Cartan integral invariants of holonomic nonconservative systems were established. Making use of the Poincare’ integral invariant as a tool, the formulation of time-domain finite element method was derived, which can be used to solve dynamic response.
