The 3D model of machine tool column of YKS5120BX3 NC gear shaper is created in Pro/E. This model is imported into the ANSYS by IGS file. The column structural static stress and deformation, the five-order modal natural frequencies and mode of vibration are obtained by ANSYS static and dynamic analysis. Based on the analysis results, this study offers a kind of reference comments for the design and...
Distributed power generation technology is an important part of smart grid. Because of its clean and efficient characteristics, it has been recognized, and obtains a strong development. Henan is a population intensive province, and consumes more energy relatively. So developing a clean and efficient energy is necessary, in order to satisfy the demands. The problem can be solved with the use of distributed...
According to the theory for measuring the information of mechanical products and with the combination of the classification of the information of mechanical products, the processing technology information of mechanical products was studied deeply, and the measurement method of processing technology information for mechanical products was presented. This method can evaluate the advantages and disadvantages...
In order to matches the large-displacement character of the compliant mechanisms, a nonlinear optimization method for designing micro-clamps is presented by combining the theory of element-free Galerkin method(EFGM) and topology optimization. The performance of the micro-clamp produced according to the design result is tested. The structural response analysis and sensitivity analysis are carried out...
This paper is based on the information axiom, combining membership function and gray relational analysis, then an advanced scheme evaluation method was presented. The traditional information axiom is only able to deal with quantitative indicators But this method can solve the problem. By this method, the membership function of fuzzy mathematics is used to deal with the qualitative indicators, and...
The element-free Galerkin(EFG) method is integrated into topology optimization for designing compliant thermal-structural microactuators, with geometrical nonlinearities considered. Taking into account its more capable of capturing the natural behavior of nonlinear compliant mechanisms than the standard finite element method (FEM), the meshfree method is employed to discretize the governing equations...
A new topology optimization method for designing thermomechanical compliant actuators using meshless methods is presented. The meshless method is employed to discretize the design domain and the bulk density field, which can avoid the undesirable mesh distortion when the standard finite element method (FEM) is applied. The method for imposing boundary conditions in the meshless method is discussed...
