The weight of platens accounts for about 70% of the entire clamping device of injection molding machine. The reduction in the weight of platen means the reduction in the cost of injection molding machine. UG NX8.0 was adopted to conduct the parametric design, and UG NX8.0 Advanced Simulation module was adopted to conduct the finite element analysis and the topology optimization design for the front platen of injection molding machine so as to obtain the quantitative conclusions that the volume of platen is reduced and the stiffness as well as the strength is improved. The maximum deformation of platen is decreased by 6.2%, the volume is decreased by 6%, the maximum stress is decreased by 6.6% and the average displacement of all the nodes in the mold mounting plane is decreased by 9.1%. The effect of optimization is obvious.

Ansys Parametric Design Language

There is currently no relevant national design standards about mast crane, so there are many of its non-standard design and a variety of forms and no attention is payed to the rationality of the design. Therefore, optimal design of the mast crane steel structure has a significant meaning for design technology of mast crane. This paper refers to a kind of parametric optimization model based on Ansys OPT, combined with finite element analysis (FEA) and stability theory. The building process and the program structure of the parametric optimization model is introduced. Corresponding program is developed by using ansys parametric design language (APDL) , which extract some parametes from FEA results, such as weight and axial force, etc, and rapid optimization design of mast crane is realized. It has a referenced meaning for optimization design of steel structure of all types of mast crane.
