Dynamic Modeling of a Mobile Mechanical System with Deformable Elements.

In this paper we present some results obtained from a dynamic response analysis of a mobile mechanical system, in two cases, when the elements are considered as a rigid ones, and when these elements are considered deformable. For both situations we propose for analysis the Newton-Euler formalism completed with Lagrange's multipliers method. The obtained mathematical models were tested on a wiper windshield mechanism which has a spatial motion. Combining the experimental analysis with the dynamic inverse analysis we obtain the connecting forces variation laws from the mechanism's joints. These forces will constitute the loading base for finite element modeling of the all mechanical system. Through finite element modeling we were obtained the variation laws depending on time, for cinematic parameters in dynamic regime. [ABSTRACT FROM AUTHOR]
