圆环在承受多个数值相等且均匀分布的径向载荷作用时,在每两个相邻载荷之间必然存在着两个节点。在节点处,径向位移为零,因此节点可作为圆环与其他构件的连接点。节点位置的确定方法,在以往的文献中少有论述。本文给出了求解节点位置的方法。当 n 个均匀分布的径向载荷 P 作用于圆环时,弯矩的表达式为 When a ring is subjected to multiple radial loads with equal and uniform distribution, two nodes must exist between every two adjacent loads. At the node, the radial displacement is zero, so the node can act as the point of attachment of the ring to the other members. The method of determining the location of nodes is rarely discussed in the previous literature. This article gives a method to solve the node location. When n uniformly distributed radial load P acting on the ring, the bending moment is expressed as
