MECHANISM DESIGN BY COMPUTER

Computers are available that synthesize and analyze complex mechanisms ranging from diaper-folding machines to aircraft landing gears. Computer programs for mechanism design are of three types: those developed by academic researchers, by industry, and by vendors of computer software. Most academic programs were developed to test new theories, and are not usually worth acquiring for general use. Programs developed in industry generally are proprietary and not available to outside users. The few that are accessible usually are too specialized to be useful in a wide range of applications. Vendor programs can be applied to the broadest range of mechanism design; they are well-documented, require little knowledge of unusual nomenclature, and are user-oriented. Capabilities and limitations of four commercially-available kinematics programs are detailed: Automatic Dynamic Analysis of Mechanical Systems (ADAMS); Dynamic Response of Articulated Machinery (DRAM); Integrated Mechanisms Program (IMP); and Kinematic Synthesis (KINSYN). To select a program, the problem must be defined. The mechanism must be classified as either planar or spatial, and a determination must be made as to whether the program should provide kinematic, static, or dynamic information about the mechanism. A decision must then be made whether the problem is one of analysis or synthesis. Illustrated are a mechanism for automobile hood linkage, a type-ball tilt mechanism in a typewriter, sewing machine mechanisms, Chevrolet Engineering Division's road simulator for tires, and a spring-reset mechanism on plows. Interactive graphics are also discussed.
