多余约束 meaning in English
excess constraint
superfluous constraint
Examples
- In order to make the mechanisms possess high efficiency , high stability , and low cost , a thorough study for constraints and overconstraints in the linkage mechanisms , self - adjusting mechanism and self - adjusting structures of the mechanisms , the degree of the influences of errors in different kinematic pairs on performance of the mechanisms , and the theory and method of designing for the mechanisms without overconsstaint was carried out in this dissertation . on the basis of the generalized constraints and on principle of designing and controlling the constraints advantageously , the conceptions such as basic constraint , statically constraint , and over - statically constraint were put forward for the first time
论文的主要研究成果及创新点有以下几部分： ( 1 )基于广义约束的概念，从有利于设计和控制约束的原则，对机构及机械系统中的常见约束进行了分类，首次提出了“基本约束” 、 “静定约束”及“超静定约束”的概念和分类定义；并首次将虚约束、重复约束、消极约束、多余约束、过约束等概念，从本质上统一起来进行定义，将其都统一称为“过约束” 。 - 2 ) quiet fixed and supper quiet fixed structure refer to the aspect of geometry composition and bearing load state , the quiet fixed structure is a geometry variable system that does not have redundant restrict . its all reverse force and inner force can be computed with quiet equilibrium equation and the relative result is uniqueness
2 ）静定结构与超静定结构静定结构是指在几何组成方面，它是无多余约束的几何不变体系；在受力状态方面，它的全部反力和内力均可由静力平衡方程所求得，且其解具唯性。
