摘　　要：推导出了矩形膨胀节在轴向、横向、角向位移下产生的力、力矩、当量轴向位移以及刚度等公式，还对ＥＪＭＡ标准矩形膨胀节的刚度公式及力矩公式作了补充和修正。指出矩形波纹角部的最大应力为位移应力，因此该部位易于破坏。The rectangular expansion joints formulae of force,moment,equivalent axial movement and spring rate etc under load of axial,lateral and angular movements respectively are deduced.The spring rate formulae and moment formulae of rectangular expansion joints in EJMA standards are complemented and revised.It also indicates that the maximum movement stress lies in the corrers of rectangular bellows which are easy to cause failure.
