摘要

本文探討雙滾珠自動平衡機構的動態特性。首先建立具有雙滾珠自動平衡機構之光碟機系統的簡化模型，利用Lagrange’s Equation推導系統的運動方程式，分析在雙滾珠的偏心量大於、等於、小於碟片偏心量之條件下，系統的平衡位置；接著探討系統參數對於平衡解的穩定性影響，其結果可作為日後設計時的參考；最後設計一模擬基台，實際量測在不同條件下，雙滾珠自動平衡機構的減振效果，與之前理論分析結果相互驗証。

This thesis investigates the dynamic characteristics of two-ball automatic balancers. A theoretic model of a CD-R drive packed with an automatic balancer was constructed first. The governing equations of the theoretic model were derived by employing Lagrange’s equations. Then we determined the equilibrium position when the imbalance of the balls is lager than, equal to, and small than that of the optical disk. The influence of system parameters on the stability of the equilibrium positions are studied in detail. These results can be used as guide-lines for designing ball-type automatic balancers. Finally, an experimental apparatus was constructed to measure the vibration-reduction effect of the automatic balancer. The experimental results agree with the theoretical results qualitatively.
