This thesis describes a novel interactive procedure for designing a scissor lift with a computer program. An optimization scheme and stress analysis are incorporated. The program determines the optimum cylinder location of a scissor lift, performs stress analysis by using the finite element method, and computes the proper cross-section sizes of the scissor arms for specified design requirements. Modeling techniques and boundary conditions of the design program are discussed. Several illustrative examples are given to demonstrate how the special-purpose code can automate an originally tedious design process, output more accurate results, and reduce design calculation time from about 8 hours for the conventional design to about 30 minutes with the new procedure.
