Modeling dynamic mechanical system behavior using sequence modeling of embodiment function relations: case study on a hammer mechanism

Wettstein, Andreas; Grauberger, Patric; Matthiesen, Sven

In engineering design, an issue for using complex simulation models in system analysis are unknown causes for dynamic system behavior, which make parameterization difficult. This paper presents a case study in which a structured system analysis is used for the parameterization of complex dynamic multi-domain models. The dynamic system behavior of an impact wrench during fastening of a bolt is analyzed and modeled using the Contact and Channel Approach for structured parameterization of a multibody simulation model. This qualitative model building serves as a basis for a simulation model that quantifies the relations of design parameters and system behavior. Comparison with experimental test results is done as a validation. With this approach, the behavior identified in the simulation model could be traced back in a structured way to its cause in the system embodiment. The simulation model represented the real dynamic system behavior with an initial sufficient precision, but showed a lack of precision in detail. On this basis, the Contact and Channel Model was extended by adding additional statistical behavior of the system. Parameters of the system embodiment were identified qualitatively to improve the simulation model. ... mehr
