The invention relates to a large-scale mechanical structure static rigidity optimizing method based on an equivalent elastic modulus, which is mainly characterized in that under the condition that actual load and restriction are applied, the equivalent elastic modulus of a part to be optimized (namely a target part) under an unassembled condition is solved by a rigidity equivalent principle, namely, the rigidity and stress deformation condition when the target part is unassembled are enabled to be same as the rigidity and stress deformation condition after the target part is actually assembled; in subsequent optimization analyzing and calculating, the unassembled target part is used for replacing the assembly part for optimization analysis. The large-scale mechanical structure static rigidity optimizing method based on the equivalent elastic modulus can convert problem of optimization of static rigidity of a complex assembly into the problem of the optimization of the static rigidity of ...

The invention relates to a ram bending deformation two-way compensating device, mainly solving the problem that the traditional draw bar compensating device causes the axial deformation of a ram because draw bars are eccentric. The invention is characterized in that the lower part of the ram (4) is provided with two compression bars (7) and a push action cylinder (6) connected with the compression bars (7); the compression bars (7) and the draw bars (2) are symmetrical up and down along the centre line of a milling spindle (1); the two compression bars (7) are symmetrical left and right along the centre line of the milling spindle (1); and the push action cylinder (6) is arranged in a main spindle box (3). The two-way compensating device does not generate the additional axial deformation while compensating the bending deformation of the ram. Compared with the traditional pure draw bar compensating method, the pressure required to be provided for the cylinder is small under the condition ...
