钢丝绳的计算理论主要有悬链线和抛物线两种理论,一般认为悬链线理论更代表钢丝绳的真实模型,而抛物线理论是一种近似模型。通过对钢丝绳两种理论的各个参数对比计算得出不同条件下的误差,并指出抛物线模型代替悬链线模型的条件,为计算带来了方便。 The calculation theory of wire rope mainly includes two kinds of theories of catenary and parabola. It is generally considered that catenary theory represents the real model of wire rope more and parabola theory is an approximate model. By comparing the two parameters of the wire ropes, the error under different conditions was calculated and the condition that the parabolic model replaced the catenary model was pointed out, which is convenient for the calculation.
