钢丝绳由许多钢丝缠绕而成 ,每根钢丝形状复杂.在设计起重机时钢绳直径一般仅是将钢绳所受的拉力考虑安全系数后与钢绳的破断拉力相比较来确定 ,至于钢绳中钢丝的应力未涉及.该文试探讨了承受轴向力的钢丝绳中股截面的内力以及绳股中形状复杂的钢丝内力和应力情况“,”Cable is composed of many steel silks wound together. The form of every steel silk is very complicated. When cranes are designed, the general diamater of the cable is affirmed by comparing the tensile force of the cable with the breaking force of the cable. In this thesis the internal force of the section of the strand in the cable and the internal force and the stress of the steel silk of the complicated forms in the strand are discussed.
