平衡吊随遇平衡的条件是:(1)各杆没有自重;(2)各杆没有变形;(3)不存在制造和安装误差;(4)相互活动部分没有摩擦。实际上,这些条件并不存在。失去了随遇平衡的前提,就产生了失衡的结果。为研究方便起见,按其原因,失衡可分为以下几种:a)杆系自重失衡;b)杆系变形失衡;c)制造安装误差失衡;d)摩擦失衡。本文仅就杆系自重失衡问题进行论述。目前,国内外杆系自重失衡补偿办法有两种:重锤补偿法和弹簧补偿法。各有其优缺点。本文首先计算失衡力及各杆自重简化力。其次对国内外流行的两种补偿办法进行评述。最后,作者提出新的补偿机构。进行了理论分析,论证其优越性。
Balance balance with the case of the following conditions are: (1) the rod is not self-respect; (2) the rod is not deformed; (3) there is no manufacturing and installation errors; (4) mutual friction parts. In fact, these conditions do not exist. Loss of the premise of the balance of events, resulting in the result of an imbalance. For the sake of research convenience, the imbalance can be divided into the following categories according to the reasons: a) imbalance of bar weight; b) unbalance of bar linkage; c) imbalance of manufacture and installation error; d) imbalance of friction. This article only discusses the issue of weight imbalance in the bar system. At present, there are two kinds of compensation methods for weight loss at home and abroad: heavy hammer compensation and spring compensation. Each has its own advantages and disadvantages. This article first calculates the unbalanced force and the weight of each rod to simplify the force. Second, comment on two popular methods of compensation at home and abroad. Finally, the author proposes a new compensation agency. Conducted a theoretical analysis to demonstrate its superiority.
