鉸鏈四桿直線機構在特殊位形下解析綜合法探討

Analytical Synthesis of Four-bar Linkage in the Special Configuration with Coupler Curve Having a 4-Point Contact with Its Tangent

摘要: 給出了在一種特殊位形情況下綜合連桿曲線具有4點接觸直線(Ball點)的鉸鏈四桿機構的解析方法.用該方法綜合鉸鏈4桿機構可預先給定欲逼近直線上的點及2個固定鉸鏈點的位置.推導出了綜合公式并給出了綜合示例,證明了綜合公式的正確性.

Abstract: A analytical synthesis method of four-bar linkage in the special configtnation, in which the coupler curve has a four-point contact with its tangent (Ball's point), is Presented.With this method, the point which is on the expecting straight-line, the direction and two frame points,can be given beforehand.And some synthesizing formulae are derived and some synthesizing examples are given. The results have proved that the formulae are correct.
