Improved Techniques for Dynamic Analysis of Earthmoving Equipment 740425

A proved concept in dynamic analysis of complex machinery is the “building block” approach. Individual components, or building blocks, of the total system are analyzed separately, and then mathematically combined to predict the total system dynamic behavior. The building block concept has become a practical design tool with recent developments in sophisticated finite element techniques and computer interfaced testing equipment. This paper describes the state-of-the-art analytical and experimental methods used to determine the component properties and assemble total system models. Specifically, the application of these methods to the dynamic analysis and design of earthmoving equipment is demonstrated.
