twist pair
解釋
雙扭線-
Nevertheless, the widely existed overconstraints in the mechanisms will make the quality of the mechanisms very sensitive to the inevitable manufacturing, assembly errors ( especially, the errors resulted from the shape and position between kinematic pair elements and their axes ). at the same time, because the internal and external uncertain factors such as non - plane characteristic of dynamic parameters of links ( such as mass distribution, inertia forces, etc. ), bending and twist of links, and the changes of environment and operating condition are inevitable, they will form the disturbance to planar constraints and make them possess the characteristic of " uncertain "
但是，平面連桿機構中廣泛存在的過約束，造成機構對製造、安裝誤差特別是運動副元素的形位誤差十分敏感；同時，由於不可避免的內部和外部不確定因素的影響，常常會造成機構運動的「障礙」及系統中某些構件的變形和運動副中的附加動載荷，引起機械的振動、沖擊、噪聲等而導致機械的效率和工作性能的降低。
