機器在運作時,因內部機構本身的質量,受重力與運動時的加速度之效應,會產生動態慣性力作用在機架上,使機器產生不必要的振動或噪音,影響機器的性能表現,此即所謂動態不平衡。
本文的目的,在研究連桿動平衡機構之動態特性,利用「等效慣性質量分析法」,建立動平衡機構之平衡力模型,以了解諸如滑塊偏置量、桿件尺寸、桿件質量分布、平衡彈簧、平衡氣壓等參數對於平衡力曲線的影響。並提出設計連桿動平衡機構的原則,利用「雙肘節位置精確點的位置合成」,合成出滿足運動要求的機構尺寸,由諸多解答中,以動態力特性為指標,作分析及比較,找出平衡效果較好的解答,提供設計動平衡機構時的參考。
研究過程將完全程式化,利用電腦輔助設計,提升計算與選擇解答的效率。建立的程式中將包含動平衡機構運動分析、動平衡機構平衡力分析、機構合成解答線、機構合成解答分佈。最後並以實際沖床為例,設計一動平衡機構。
The characteristics of linkage balancing mechanism is first discussed on the base of Newton’s 2nd Law. Employing the Equivalent Mass Inertia method to model the balancing force of the linkage balancing mechanism. To synthesize the dimensions of the balancing mechanism by 2 precision toggle positions synthesis theory, establish the solution line, show the distribution of the solutions. Find the suitable dimensions for balancing mechanism within the solution line that satisfied the dynamic characteristic of design requirement. The study utilizes the computer-aided method to analyze the motion of the balancing mechanism, plot the curve of dynamic forces, establish the solution line and choose the right solution. At last, design a set of dimensions of balancing mechanism as a balancer for a press machine.
