【Abstract】 Finite element method is used to static and modal numerical simulation of hydraulic numbering press. Static stress and deformation contours, natural frequencies and mode shapes of the first five orders are obtained when the body of the press is with various of materials and cross section shapes. The results provide theoretical basis for designing new product.更多还原
