    Abstract: 以往變轉速機構之應用,其共同的假設為伺服馬達皆能產生所設計出之輸入桿運動特性,以便完成機構所需之輸出桿運動特性。然而此要求往往導致伺服馬達在單一週期之內即需要作劇烈之加速與減速,所需之功率極大,且會將能量耗損在加速與減速之上。因此,如何將能量作適當的轉換與釋放,成為伺服馬達需要作劇烈之加速與減速時所面臨之重要課題;而慣性矩可變之飛輪為此問題引出一線可行方案。本計畫首先將前期計畫所產出之多種可變慣性矩飛輪概念機構,擇一設計出可用之可變慣性矩裝置。其次,為了找出可用之慣性矩函數,本計畫選擇一適當的變轉速機構作為載具,此機構以一既定之轉速軌跡作變轉速運轉。然後以最佳化之方法設計出一系列之可變慣性矩軌跡,搭配該既定的變轉速軌跡作同步運轉,目標是降低機構所需扭矩、降低所消耗之輸入功、以及降低輸入桿之動能變化,以期了解可變慣性矩飛輪系統所能產生之性能增進與能量節省效益,以為將來之此機構技術之推廣及移轉建立基礎。In the recent years, when the variable speedmechanisms were used, almost all of theresearches had the same assumptions that theservomotors can generate the desired input speedtrajectories. However, when the servomotor ofthe mechanism must perform dramaticacceleration or deceleration, the required powerof the servomotor becomes very large and it may cause unnecessary energy dissipation. Therefore,how to store/transfer/release the energy duringthe motor’s acceleration and decelerationbecomes an important issue for variable speedmechanisms. The proposed “variable momentof inertia flywheel” seems to be a candidatesolution of this problem.At the beginning of this project, we choose aconcept of the candidate variable moment ofinertia flywheel devices from those conceptualmechanisms which have been derived in thepreceding project. Then select a variable speedmechanism as its platform. Design amechanism to couple the variable speedmechanism and the variable moment of inertiaflywheel device. This combined mechanism ispresumed to run at a prescribed velocitytrajectory. The purpose is to find usable momentof inertia trajectories using optimizationtechnique to meet the objectives of reducing therequired torque, reducing the total work (energy)input to the system, and reducing the variation ofkinetic energy of the wheel. The results of thisstudy can let us understand the efficiency of thevariable inertia flywheel can device can do to theoriginal variable speed mechanism. The resultsof this project may also lead to possiblepopularization and technique transfer in thefuture.
