摘　　要：天津钢管集团股份有限公司钢管研究所从美国动力系统公司(DSI)引进的Gleeble 3500热机械模拟试验系统由于带有数控热扭转单元而成为目前国内该系列机型中配置独特的材料热-力研究实验装备。介绍了处于扭转状态下经受热机试验的材料因发生形变的力学境况不同,表现出不同于在拉伸或压缩试验模式下所持的性质特征,提出了该模拟试验中存在的问题以供参考。Equipped with the hot torsion Mobile Conversion Unit (MCU), the digitally controlled Gleeble 3500 System (manufactured by Dynamic Systems Inc.) introduced by Technology Center of Tianjin Steel Pipe Corp. has been the only thermal -mechanical physical simulator of its configurational family in China. It is introduced that in torsion condition the thermal -mechanical test materials show different mechanical deformation from standard uniaxial tension or compression tests and different material responses and properties. The problems occurred in simulation test are put forward for reference.
