摘要
本研究之目的在於分析及發展對於可變慣性矩飛輪之混合動力系統可行的設計，經由本研究可系統地合成一引擎一飛輪及一引擎一飛輪一電機之混合動力系統。首先以功能動力圖可將現有之系統轉換成簡單的圖示表示，可表示其構造、功能及其系統複雜度，接著系統化發展所有可行之一引擎一飛輪及一引擎一飛輪一電機構造圖及功能動力圖圖集，並且評估其功能與複雜度。接著針對一馬達一可變慣性矩飛輪使用行星齒輪組及一制動器建立運動及動力分析模式，並搭配數值分析軟體ADVISOR，經由所建立之煞車回充作動邏輯及操作模式可完成完整的模組化分析模式。最後以ECE，ECE+EUDC及紐約巴士行車模式測試此套混合動力系統，數值分析的結果可呈現可變慣性矩飛輪所提升系統效率。本研究完整地整理所以有一引擎一飛輪及及一引擎一飛輪一電機可能之設計概念，並以一馬達一可變慣性矩飛輪為例作完整之系統效率分析。

The purpose of this study is to analyze and to develop the possible design concepts for the hybrid power systems with variable inertia flywheel. Through this study, we are able to synthesize and evaluate the hybrid systems and to compose of the hybrid power system with 1 engine, 1 flywheel and 1 engine, 1 flywheel, 1 electric machine. In the study, firstly, the “functional power graph” is developed, which can transform the traditional mechanical diagrams into a simplified graph for representing its mechanical structure and function. The atlases of structural graphs and functional power graph are built by a systematical design method, which includes all possible concepts of the hybrid power systems. The system for studying is 1 motor, 1 variable inertia flywheel which is used as the energy storage device, a planetary gear set, and a set of actuators. Then, the kinematic and kinetic equations of the hybrid power system are developed in order to establish the relationships of the speed and torque of all elements, and the specific speed and torque of the output can be found by using the software “ADVISOR” in various operation modes. Thus, with a prescribed mechanical brake energy recovery system model and a control model, a comprehensive analysis can be achieved. Finally, various driving modes, such as ECE, ECE+EUDC and New York Bus driving mode are investigated in order to demonstrate the characteristics of the hybrid power system. The numerical results show and conclude the effectiveness of the variable inertia flywheel, and the improvement on the efficiency of hybrid power systems.
