如果我们取上一时刻的值作为下一时刻的初值,根据前文首先初始状态下三个量的关系就不满足广义alpha假设,之后的迭代计算中,我们对三个量分别加上满足基本假设的增量,那么根据线性叠加原理,加完的结果应该是不满足基本假设的,并且可以说一定不满足。但如果初值就满足基本假设,那么不管迭代多少次,加上满足基本假设的增量...
之前在使用一款力学仿真软件(Openfast)计算时,总是出现不收敛的问题,怀疑是数值计算问题。所以后面详细的分析了其中使用的广义α法的收敛性。 动力学数值求解方法常用叠加法(Duhamel 积分)、直接积分法(如newmark-beta法),Generalized- α 法是直接积分法的一种。 以单自由度动力学系统为例,对Generalized- α 方法计...

We extend the concept of proximal-point mappings associated with generalized $m$-accretive mappings to the generalized $\\alpha\\beta$-$H((.,.),(.,.))$-mixed accretive mappings and prove that the proximal-point mapping associated with generalized $\\alpha\\beta$-$H((.,.),(.,.))$-...
