【Abstract】 Aimed at multi dimensional and nonlinear feature of the mechanical behaviour of multi layer spacer plate group of huge hydropress, this paper has analysed the regularity of the mechanics behaviour of spacer plate group of 300 MN hydropress, by using a multi body contact finite element program developed by the author. The relation between the geometry space state of the spacer plate group and the mechanism of the abnormal yield of the spacer plate group has been explained. Several criteria for the design and the use of the spacer plate group have been put forward.更多还原
