However , the current researches in human coordination are limited to topological analysis and fixed joint velocity ratios , and coordination of human movements has not been described in a quantitative and very effective way 目前对于人体运动协调规律的描述仅限于轨迹拓扑结构分析和关节角度的固定比例变化,尚不能对人体运动协调规律进行有效的量化描述。
Abstract : cable - stayed is used to cable suspension , but cable force is calculated by manual , and only for less than 5 segments , and the prescion is poor . this paper puts forward “ zero moment method ” , which can not only calculate more segmental soupe force , but both temporary joint and fixed joint during construction . the mechanical concept is clear , and it is easy for calculating . it is fit for program , and the illustrations prove that the methods are right 文摘:斜拉扣挂在缆索吊装中经常运用,但扣索索力多采用手工计算,且多用于5段以内的吊装,计算复杂,精度低.本文提出“零弯矩法” ,可计算任意多段扣索索力,既可计算拱肋在施工过程中各节段临时铰接,又可计算各节段固结的情况,将两种连接方式统一成一种计算方法,力学概念清楚,计算简便,适宜程,文中最后用示例证实本方法的正确性
