摘要
钢丝绳是传递力和承受作用力的柔性物体 ,它在船舶上有着广泛的应用 ,同时具有不可忽视的重要性。由于钢丝绳的成绳、结构、受力三大特点 ,使其产生了复杂的应力状态 ,一般力学是以刚体为模式和在小变形(即弹性变形 )范围内来研究问题的 ,当某些理论被直接用到钢丝绳这种柔性物体上时 ,有些问题就会不容易搞清楚 ,甚至会使人们误解和忽视。本文结合钢丝绳的力学特点 。
Ship's wire cable is a flexible tool to transmit and bear the force, so it is of great importance and widely used onboard the ship. Due to its three main features of ropeforming, construction and force loading, a complicated stress condition occurred. In the normal mechanics, this is examined by assuming its rigidity as the mode and in the domain of constrained extent(elastic deformation). But when some principals are directly used for such flexible tool of wire cable, some problems are found hard to be explained, even may lead to misunderstanding or ignoring. This paper did a discussion on these problems based on the mechanical characteristics of wire cable.
