displacement principle meaning in English

移位原理

This paper employs the dynamic - static force principle to simplify the mathematical models , and employs the virtual - displacement principle and adopts the sor digital algorism to extract the dynamical performances . the solutions extracted is coincidental with the practical situations
本论文应用了达朗贝尔原理简化数学模型，并应用虚位移原理和sor迭代法求解机构的动力特性，求得的仿真曲线与实际情况比较吻合。
Then each . cable - strut - membrane unit is analyzed by adopt the non - linear finite element analytical method . according to virtual work principle , the equation of solving is formed , from the timid displacement principle , derive and happen to ask the equation of solving . through the whole n - r method , cooperative form - finding of the cable - strut - membrane structure will be realized
然后，采用非线性有限元分析方法，对各个单元进行分析，由虚位移原理，推导出求解方程，通过全n - r法迭代，实现索杆膜结构的协同找形。
