Dynamic model of continuous miner ' s cutting arm based on distributed mass law 连续采煤机截割臂分布质量法的动力学建模
And the needs for integrated access , transfer , management of geographically distributed mass datasets are also increasing 对这些地理上分布的海量数据进行一体化访问,传输与管理的需求也日益突出。
Bodies are elastic , springs have a distributed mass , electrical leads have a distributed resistance , and temperatures vary across a body 物体是弹性的,弹簧有分布质量,导线有分布电阻,物体中的温度各点不一。
This geologic feature , among others ? mountains , valleys , ridges , trenches and such ? distributes mass unevenly about the planet ' s surface , thereby making the pull of gravity vary slightly 这个地质构造与其他诸如高山、谷地、洋脊、海沟等构造,是使得地球表面的质量分布不均匀的主因,造成重力的作用略有差异。
This paper presents a synthetical method of correcting finite element model , which can simultaneously correct static and modal features of the concerned structure . the objective could be boundary condition , distributing mass and size parameters 本文提出了有限元模型静力、模态特性的综合修正方法,修正对象为结构的边界条件、质量分布和尺寸参数。
