可變慣性飛輪之概念與構形設計
Conceptual and Topological Design For Variable Moment of Inertia Flywheels
摘要
在一個機械動力傳遞系統中，馬達或引擎為常見的動力來源，尤其是固定輸入轉速之機構，其設計上輸入端均會配置一個定慣性飛輪，藉此儲存動能、平衡動力。然而某些變轉速機構在設計上輸入轉速就不是定轉速，假使機構之輸入桿必須在極劇加速或減速的條件下運作，定慣性矩之飛輪將無法滿足不同轉速與負荷間的要求。所以本文主要是以改變飛輪質量慣性矩的概念為出發點，目的為合成出新型的可變慣性飛輪機構，使所產出的新型機構能具備原有定慣性飛輪的功能在與動力源結合上能滿足不同轉速與不同負荷間運動特性的要求，進而讓動力機械能達到多功能使用。本文首先介紹可變慣性飛輪機構架構及原理，由於目前關於可變慣性矩機構之研究並不多，所以本研究以光碟機的雷射讀寫頭及速克達機車之無段變速機構中前皮帶盤的作動原理為概念基礎，設計一個可行的 機構作為可變慣性飛輪機構的原型，並分析原型機構的拓樸構造特性，再加入此可變慣性矩機構所需的設計需求，作為構造合成的基礎，接著利用顏氏創造性機構設計方法﹝3﹞﹝9﹞為基礎，設計限制條件，並且加入許正和機構構造設計學﹝7﹞所提之 (可動度)的觀念為輔助，將可動度由2逐一探討至5，合成出符合設計任務與需求的可變慣性飛輪機構，最後產出了三桿三接頭與四桿四接頭的可變慣性飛輪機構。為了使新型機構滿足實際的需求，本研究並對所創新之機構，以一實例設計使用SolidEdge軟體呈現，並運用3D軟體Inventor模擬其運動過程，最後進行運動與動力的分析，藉以驗證可變慣性飛輪機構能在無干涉情況下正常作動。

In a machine motive delivery system, the motor or engine is familiar motive sources, the organization that particularly is a fixed importation to turn soon, it design to carry to all will install up the importation a certainly inertia flywheel, storing the kinetic energy, equilibrium motive by this. However some changes to turn soon the organization on the design the importation to turn soon and then is not an operation under the condition that certainly turn soon, if the importation bar of the organization have to in the pole play acceleration or the deceleration, settling the flywheel of the inertia will can't satisfy the dissimilarity turns soon with carry of request. So this text mainly takes the concept of the inertia of the change flywheel quantity as the point of departure, in order to synthesize the new variable and inertia flywheel organization, the purpose make the new organization produced be able to have original settle the function of the inertia flywheel, at combine with the motive source up can satisfy the dissimilarity to turn soon carry with the dissimilarity the request of the exercise characteristic, then let the motive machine be able to reach the multi-function usage. The thesis introduces the foreign variable and inertia flywheel organization structure and principle first, due to currently domestic study concerning variable and inertia organization also not much, so this study with the Laser of the CD driver reads and write the head and the motorcycle Continuously Variable Transmission(CVT) its front pully to make to move the principle for concept foundation, design a prototype that the viable organization is the variable and inertia flywheel organization, and analyze the Topological structure characteristic of the prototype organization, then joins the design need that this variable and inertia organization needs, be the foundation that the structure synthesizes, immediately after makes use of the Yan, H. S., ﹝3﹞﹝9﹞ to creative organization design method as foundation, the design limits the condition, and join Hsu,.﹝7﹞ to allow the organization structure design learns lift it (degree of motion ) of in order to lend support to, the idea will be able to move the degree by 2 one by one inquire into to 5th to synthesize to match to design the mission and demanding and variable and inertia flywheel organization, finally produce three bars three deal with contact with four variable and inertia flywheel organizations that deal with contacts of four bars. For making the new organization satisfied the actual need, this study also to creative of organization, present with a design, by use SolidEdge software view and imitate it with the 3 D software(Inventor) exercise process, finally carry on the exercise and dynamical analysis, by canning normally make to move while having no interference condition with identifying the variable and inertia flywheel.
