Test Result

In order to study the effect of tire operating mode on its safety performance, a high-speed tire test-bed was put forward. The dynamic characteristic of drum was important for test result. To avoid the resonance of loaded drum during operation, the topological optimization analysis of drum with I-shaped structure was fulfilled with the element density as variables and the volume reduction of fifty percent as constraint condition and the first natural frequency as objective function. The optimal density distribution of drum was obtained within the constraint of the first natural frequency. Based on the analysis result of topology optimization, the drum structure with I–shaped was modified. The structure size of the new and improved drum was optimized with 50 iterative calculations using ANSYS. On the condition that the first natural frequency of drum was over 60Hz, the structure size of drum was optimal when the rate of the first natural frequency and total weight was highest and equaled to 0.05391. The optimization results showed the first natural frequency of drum was raised by 21.972Hz and its total weight was reduced by 69.95Kg.

In order to improve the situation that the design of microactuator is mostly based on the intuition and experience of researchers, the method of continuum topology optimization using the nodal density is introduced to the conceptual design of microactuator. This new method can ensure C0 continuity of density field in a fixed design domain. The ratio of mutual energy to strain energy of the mechanism is regarded as the objective function, where, the mutual energy and strain energy describe the kinematic function and structural function of microactuator respectively. The final configuration of microactuator is decided on the guide of conceptual design combined with the given working conditions. The finite element method is applied to analysis the transmission ratio and clamping force of microactuator. The prototype of the microactuator is fabricated by using micro-electroforming and SU-8 photolithography techniques and the displacement of the micro actuator is measured by using the stereo vision microscopy. The experimental results show that the properties of the micro actuator can satisfy the designing demands. This topological optimization method based on nodal density plays an important role in guiding the structure design of micro actuator.

If finite element models for beam structures of the rail weld CNC fine milling machine are built, and static analysis and modal analysis are used to model the beam structure, it can be concluded that the beam has sufficient margin in strength but lower stiffness. The beam structure is optimally designed with orthogonal test. After optimization, the beam body has been obviously improved in stiffness, and reduced lightly in weight.

In order to improve the riveting precision, the finite element method and topological optimization design based on the variable density method were employed to design the pedestal of horizontal rocket rivet fixture. Topological optimization model was set up based on static analysis of the original designed pedestal under various typical load cases. Topological optimization results of various load cases were compared with original pedestal. The result showed deficiencies of the original pedestal, and a new model was built based on topological optimization results. The analysis of topological model was carried out by applying the finite element method. The results show that the stiffness of pedestal was remarkably improved; the stress distribution was more homogenized and the displacement of the guide rail was decreased after optimization. This method could also provide reference and guidance for designing other complicated structures.
