Abstract
This paper presents a methodology for the model-based assessment of the NVH behaviour of a tractor with hydrostatic mechanical power split transmission (PST) within the product development process. The aim of the simulation methodology is the assessment of structureborne and airborne noise caused by transmission excitations. Due to numerous interactions and couplings within the system, a multi-domain overall system model is proposed. The model combines the aspects of hydrostatic force excitation, structural dynamics and subsequent acoustic response. In this paper, the main components of the simulation model are introduced and its application is demonstrated for a given series tractor with PST. Simulation results are shown and compared with measurement results. The results are discussed and an outlook on future work is given.
