分析高速磁浮试验线动力轨系统中汇流排接头两种方案,因动力轨系统的中间接头和膨胀接头部分导电后的热膨胀产生接触应力,在满足导轨力学性能的前提下,利用有限元软件,满足接头的导电性能下对比两种接头设计方案螺栓紧固后接头的接触状态。通过计算,分析接头在符合导流、结构支撑功能的基础上,确定最优方案,并计算热膨胀性引起的最大摩擦力,满足设计要求。 Analysis of high-speed maglev test rail power rail system busbar joint two options, due to the power rail system intermediate joints and expansion joints after conductive thermal expansion contact stress, to meet the mechanical properties of the rail under the premise of the use of finite element software to meet Conductivity of the connector under two kinds of connector design comparison Bolted after the contact state of the connector. Through calculating and analyzing the joint, the optimum scheme is determined based on the function of diversion and structural support, and the maximum friction caused by thermal expansion is calculated to meet the design requirements.
