摘要

针对石油钻机液压刹车盘瞬态温度场,建立了有限元仿真分析模型,并运用ABAQUS对模型进行热-机耦合仿真计算,重点研究了参数改变对温度场和应力场分布的影响。在不改变刹车条件的情况下,仅仅改变对流换热系数、制动时间、热膨胀系数、热传导系数、摩擦因数等参数,得到的温度场、应力场分布及相关结论是一致的;对于刹车盘,降低整体的温度和应力,可以通过增大对流换热系数、减小热膨胀系数、增大热传导系数、减小摩擦因数来实现。仿真分析结论为研制性能更好的刹车盘提供理论指导。

Abstract

The finite element simulation model of transient temperature field of drilling rig hydraulic brake discs is built up. The thermal- mechanical coupling simulation and calculation of model is carried out by using ABAQUS. The influence of parameters changing on distribution of temperature field and stress field is studied specially. The distribution of temperature field,stress field,as well as related conclusions are consistent when the parameters of convective heat transfer coefficient,braking time,thermal expansion coefficient,thermal conductivity,friction coefficient are changed only but braking conditions. For the brake discs,reduction in its holistic temperature and stress could be achieved by increasing the convective heat transfer coefficient and the thermal conductivity,reducing the thermal expansion coefficient and the friction coefficient. A theoretical guidance for optimization design of brake disc is provided by the conclusion of simulation analysis.
