Under certain pre - tension from flange joint bolt, leakage of flange sealing had an obvious decrease, thus resolving sealing failure in cover flange of heat exchange.
在一定法兰连接螺栓预紧力作用下,法兰密封泄漏明显减少,从而解决了热交换器封头法兰密封失效的问题。
As the bolt tension increase, the tension of rail web, stress of joint bar and stress of joint bolt would increase accordingly, but the displacement of rail would become smaller.
螺栓扭矩增大,接头区钢轨轨腰拉力、夹板应力、螺杆内应力都会增大,而钢轨位移会随着螺栓扭矩的增大而减小。
Based on the 3D analysis result, shear models of ring joint bolt is built and shear parameters between rings needed in 2D analysis with beam-spring model can be obtained by this shear model.
然后,在对三维有限元分析结果研究的基础上,建立了环缝处的纵向螺栓剪切模型,利用该模型可以计算得到错缝拼装衬砌二维梁-弹簧模型中环间剪切弹簧的刚度;
