| Abstract: | In order to improve the damping performance of hydraulic tensioner of the chain in the process of vibration, a simulation model was established in the AVL Excite_TD based on the dynamics analysis. The damping energy was proposed as the evaluation index. The range and variance analysis based on the orthogonal experiment were employed to explore the influence of tensioner parameters to the damping performance and realize the optimization of tensioner key parameters. The damping energy can be increased by 59.70% , after parameter optimization and reach 3. 273 1 - 5. 133 7J under the excitation frequency of 25 - 200Hz . The result shows that the optimized tensioner has a good damping performance under different frequency. |
