This paper studied the original rubber suspensions, which found that the original rubber suspension has high transfer ratio, not conducive to energy attenuation. In view of this situation, redesigned of the new rubber suspension, the new rubber suspension was studied by 3D numerical analysis, the results show, the new suspension on the structure and mechanical properties can meet the needs of the engine. The new suspension and the original suspension are doing the contrast test, the results show, the new suspension has the low transmission rate, and transmission rate increases with the speed change relatively flat, which to improve the comfort of the car.

Initial Results

The mechanical properties of the steering column have a significant influence on the comfort and stability of a vehicle. In order for the mechanical properties to be improved, the rotary swaging process of the steering column is studied in this article. The process parameters, including axial feed rate, hammerhead speed, and hammerhead radial reduction, are systematically analyzed and optimized based on a multi-objective optimization design. The response surface methodology and the genetic algorithm are employed for optimal process parameters to be obtained. The maximum damage value, the maximum forming load, and the equivalent strain difference obtained with the optimal process parameters are, respectively, decreased by 30.09%, 7.44%, and 57.29% compared to the initial results. The comparative results present that the quality of the steering column is improved. The torque experiments and fatigue experiments are conducted with the optimal steering column. The maximum torque is measured to be 260 NM, and the service life is measured to be 2 weeks (40 NM, 2500 times), which are, respectively, increased by 8.3% and 8.69% compared to the initial results. The above results display that the mechanical properties of the steering column are optimized to verify the feasibility of the multi-objective optimization method.

Ferromagnetic Particles

Magnetorheological (MR) fluids are suspensions of micron sized ferromagnetic particles dispersed in varying proportions of a variety of non-ferromagnetic fluids. MR fluids exhibit rapid, reversible and significant changes in their rheological (mechanical) properties while subjected to an external magnetic field. In this paper, a double-plate magneto-rheological fluid (MRF) clutch with controllable torque output have been designed. Electromagnetic finite element analysis is used to optimize the design of the clutch by using the commercial FEA software ANSYS.

Structure Optimization Design

This paper uses the ANSYS software to analysis the outer arm opening angel(OAOA) and the outer arm arc angle(OAAA) of W-type metallic sealing ring which can effects on the mechanical properties,obtained in that when the OAOA choose from 1.398°to 14.156 °and the OAAA choose from 30.21° to 59.5 °, the mechanical properties of the sealing ring can satisfy the requirement of use. Then using the MOGA optimization algorithm to optimize the design of W-type metallic sealing ring, and find when the OAOA choose 3.39°and the OAAA choose 32.18°are the optimal design of the W-type metallic sealing ring.
