Formulation and Numerical Methods in the Computer Evaluation of Mechanical Dynamic Systems,

Abstract

Use of the computer for design analysis of mechanical dynamic systems can be effectively approached through the development of type-variant programs. For background this paper reviews the architecture and experience with DAMN, a completed, successful program which performs the dynamic analysis of any two-dimensional mechanical work irrespective of degree-of-freedom, constraint and amount of displacement. Then some relatively new methods for automated formulation and numerical analysis are discussed, particularly sparse matrix methods and the Gear algorithm for numerical integration. These appear to promise faster and more stable numerical evaluation. (Author)
