A Practical Approach to Designing Four-Bar Linkages for Guiding Rigid Bodies 780484
A computer program has been written to help in the synthesis of four-bar linkages. With the input of the required four positions of a guided body, the computer solves for a very large number of the solutions and simplifies the user's search for the “best” four-bar linkage. The computer then examines this linkage for range of travel and discontinuities throughout this range. The program can also calculate the transmission angle range and classify the type of motion. If a graphics display is available, the linkage can be displayed and animated. The program is written with conversational input and output, including optional instructions for new users.
