Distributed multibody dynamic analysis within product development

A method that supports distribution of multibody dynamic analysis is proposed and developed. Ethnographic methods are used as a means for gaining a deeper understanding of the engineering analysis work practice, and the findings form the base for a cooperative design of the system. The concept of design rationale is applied in order to deal with current problems of engineering analysis, such as irrelevant input and output, as well as satisfying the need for useful, real-time feedback. The web based simulation environment, applied to vehicle system dynamics, contains the simulation packages ADAMS and MATLAB and incorporates database technology. The possibility to distribute simulation models and results, from simulation experts to design experts and engineers, as well as subcontractors, is created. The proposed method requires changes in the existing multibody dynamic simulation methodology regarding aspects of incorporation in product development theorie
