摘要
针对深海光电复合缆绞车牵引系统的复合缆和卷筒的设计缺乏理论依据的关键问题,根据光电复合缆的特性和大容量收放的特点,运用微积分和MATLAB仿真的方法对复合缆在双卷筒上的受力进行详细分析,得到牵引卷筒上复合缆力学模型,进而讨论了牵引卷筒上复合缆的张力衰减情况。最后,基于ANSYS软件对复合缆进行有限元分析验证缆绳应力变化。仿真结果证明,所建立的牵引卷筒上缆绳的力学模型符合条件,为大载荷绞车的牵引系统设计提供了理论依据,有一定的工程意义。
For deep sea traction systems of optic/electric composite cable winch, lack of theoretical basis is a key issue of composite cable and drum designing. According to the performance of composite cables and characteristics of large capacity control, composite cable force analysis in dual drum was carried out using calculus and Matlab simulation method. The mechanical model of composite cables on drums were obtained. The tension changes of composite cable on traction drums were then discussed. Finally, based on ANSYS software, finite element analysis on composite cable was made to verify the stress changes. Simulation results show that the established mechanical model of the traction cable has met the criteria. This study has provided a theoretical basis for winch traction system design subjected to large loads, hence it is of certain engineering significance.
