A new complementary energy stationary value principle in elastic dynamics is presented and proved. 本文首先提出并证明了一个动力学余能驻值原理。
In this paper we improve the CGRS algorithm, and then make a simulation experiment to analysis the stationary value quantitatively and compare the performance of the improved algorithm and the old one. 本文对CGRS算法进行了改进,然后通过模拟实验对该固定值(SV)进行定量分析,同时比较了改进后的算法和旧算法的性能。
On the ground of the potential energy stationary value theory, the formulas for stability calculation are developed and compared with the existing formulas. 根据势能驻值原理推导出了稳定性计算的公式,并与现有公式进行了比较。
The element rigidity equation of spacial beam element was deduced using nonlinear geometric equation and total potential energy with stationary value, and the characteristic equation of the first type stability. 利用非线性几何方程和总势能驻值原理推导了空间梁单元的刚度方程,并由此建立了第一类稳定问题的特征方程。
But the algorithm only simply uses stationary value to evaluate the link performance. 但是,CGRS算法仅仅简单地用固定值(SV)来衡量链路性能高低。
