摘　　要：硫化机机架不但要满足强度要求,还要满足一定的刚度要求,螺栓联接方式和预紧力影响整机的刚度。文中采用HyperMesh软件建立硫化机机架赫兹接触理论下的螺栓联接模型,分析了不同的螺栓预紧力对机架整体刚度和强度的影响,为硫化机机架的螺栓连接方式设计和预紧力计算提供参考。The frame of the vulcanizing machine does not only meet the strength requirements,but also meets the stiffness of requirements.The bolt-joint type and the preload force have an effect on the stiffness of the machine.The bolt-joint model of the frame of the vulcanizing machine in the theory of the Hertz contact was establised with hypermesh.The effect on the stiffness and the strenth of the frame was anlyzed,whieh caused by different prload on the bolt. This article will be a good reference for the design of the bolt-joint type for the frame of the vulcanizing machine and the calculation for preload.
