Tie rod preload analysis of a 1OOMN hydraulic press

摘要：

　　The classical preload design method of prestressed frame of hydraulic presses is based on the assumption that the beams of the frame are rigid,which is not agree with practice.In order to eliminate the unbalance load of the frame ofa 100MN hydraulic press due to improper prestressing,tie rod preload distribution in prestressing of the frame is researched with respectively mechanics of materials and the finite element methods.According to mechanics of materials and finite element analysis results,reasonable tie rod preloads and sequence of preloading are obtained and the unbalance load of the flame of the hydraulic press is solved.It also provides references for the preload design of prestressed frame of hydraulic presses.
