摘要: |
本文提出了一种考虑界面力影响的自由界面复模态综合法。根据模态加速度法导出了部件的物理坐标表达式,再根据系统的虚功原理导出了系统广义坐标的运动方程,从而大大地缩小了系统的独立坐标数。并且在执行过程中不需求出部件的全部复模态。该方法很适应于系统各部件分散情况下的单独实验和计算,从而使得计算和模态试验更有效地结合起来。 |

Application of Mode Accelaration Method to Free-Interface Complex Mode Synthesis |
Chen Xingguo, Zhou Kejian |
Abstract: |
A complex mode synthesis method for the consideration of the effect of adjoint force is preserted here. First,the expression of component displacement vectors is derived by mode accelaration method. Then,the equations of motion in generalized coordinates are derived by virtual work principle. Thus,the number of independent coordinates is greatly decreased and only a few lower complex modes of component are required in synthesis. |
