The function generation method presented in this paper is based on consideration of the equations of motion of a four-bar linkage with an assumed input of θ̇1 = 1 rad/sec. For a specified input-output relationship, the task of synthesizing an appropriate four-bar linkage is reduced by this method to a problem of selecting two parameters: θ̇2 —the angular velocity and θ̈2 —the angular acceleration of the connecting rod. The selection of these parameters is governed by certain conditions imposed on the performance of the four-bar linkage function generator. Using this method, two specific problems are solved and discussed in detail.
