Vibration Dampers

To reduce the torsional vibration of vehicle power transmission system (VPTS), a torsional vibration model with multiple degrees of freedom (MDOF) of VPTS was established. The scheme of equipping torsional vibration dampers (TVDs) on the driveshaft was employed by the calculation of the forced vibration and the free vibration of the VPTS. The energy method was used to optimize the parameters of single-stage, two-stage parallel and two-stage series TVDs based on the principle that balances the damping effect and lightweight design. On the basis of this, the parameters of the models incorporating TVD and elastic couplings were optimized. Results showed that the proposed method can ensure the damping effects of TVD and realize the lightweight design.

To verify the damping effect of dual mass flywheel, the experiment is designed in use of power-transmission test-bed and rev-torque testing apparatus, and dual mass flywheel of DCT transmission system DQ250 is used to test its damping effect in the experiment. Kinds of conditions of car, like idle condition, run condition, climb condition, are simulated in experiment. The results show that different engine revs and loads, different damping effects of dual mass flywheel. The high engine rev and the more load, the better damping effect of dual mass flywheel.

Abstract Synchronous joints are an important part of the SAR antenna deployment mechanism. They are the key to the synchronized deployment of antenna. By means of mechanism combination and deformation, a new type of synchronous joint with a precise cable drive system is designed in order to meet the requirements of SAR antenna deployment mechanism. This study mainly focuses on the design of the synchronous joint, including the system design and the precise cable drive system design. By applying a preload to the drive cable, the transmission gap is reduced, and the accuracy and efficiency of transmission are improved. This paper focuses on the theoretical calculation and analysis of the preload and system stiffness of the precise cable drive system. Based on the Euler equation of the flexible friction drive, the stiffness formula of the cable drive system is derived. In addition, the main design parameters affecting the stiffness of the cable drive system are analyzed parametrically. The comparison between the results obtained from the system stiffness experiment and the theoretical calculation result indicates that the experimental values are slightly smaller than the theoretical values, and the trend of change is basically consistent. This experiment therefore verifies the validity of the stiffness calculation formula and theoretical analysis.

Simple Regression

This paper deals with face gear design. The goal is to propose a simple formula for predicting the width of the wheel as a function of the main design parameters. A specific software was used to achieve this goal. This numerical tool is able to simulate the geometry and the quasistatic loaded behavior of a face gear. The statistical method used for analyzing the influence of data is described: The design of experiments leads to a simple regression model taking into account the influential parameters and their couplings. In the last part of this paper, the results of the formulas are compared to those of the software and an optimal design is proposed based on the regression model.
