碩士 === 大葉大學 === 機械與自動化工程學系 === 100 === This thesis aims to design a series hydraulic hybrid system platform for testing the hydraulic hybrid vehicle by using the existing hydraulic components on the platform. The platform can simulate real driving conditions by the mode setting for real driving situations. The experimental data of energy recovery in driving mode are discussed in order to develop hydraulic hybrid system in a real vehicle. At first, the hydraulic circuit for the series hydraulic hybrid system is designed, then Matlab/Simulink is used to build the model of the platform. In the simulation platform, we define the steps for real operations. The data from the simulation are recorded and compared for discussion of the efficiency. Then, the CAD software, SolidWorks, is used to build 3D models of components of the test platform and the real hydraulic components are integrated into it to achieve the desired operation modes. In the platform, the pressure sensors and encoder are used to measure the pressure signals of accumulators and the rotational speed of flying wheel respectively. After building the hydraulic hybrid system platform, PLCs are used to control the platform and an AD/DA card installed in a PC controller with Matlab/Real-time Window Target as the real-time OS. The dada recorded from the platform are verified and compares with simulation results.
