For comprehending its performance and corresponding influential parameters, the theoretical model is built up to analyze its characteristics. Besides, finite element analytical method is used to confirm its structural stress in order to ensure the application safety. Furthermore, the modern CFD-analytical software (Computational Fluid Dynamics) is applied to simulate the dynamic flow behavior of damper to get the relationship between damping force and speed. Cooperating with the senior design and manufacturing experts of Hydraulic Technology Co., Ltd. Brant, the performance of the developed damper will be experimentally tested by applying their self-developed dynamic damper testing equipment. The experimental testing results are then used to derive the relationship between damping force and dimensions. Through analyses and experiments, the performance prediction system for hydraulic damper is developed. The performance prediction system for hydraulic damper can reduce the development time, and the systematically collected experimental data can enhance the simulation efficiency. In efficient response to diverse customer needs, different damper performances can be realized and supplied in customized and modular forms. The aim of this project is to enhance R&D capability, production technique and production efficiency of domestic hydraulic damper, so that it can preclude the monopolization of foreign products and promote international competitiveness.液壓阻尼器流體動力學分析性能預測系統Hydraulic damperCFD-analysisPerformance prediction system
