VIRTUAL PROTOTYPE APPLICATION TO HEAVY-DUTY VEHICLE GEARBOX CONCEPT

Abstract eng:
This paper deals with application of virtual prototype to the heavy-duty vehicle gearbox concept. First the methodology is developed and tested on the single-stage gearbox concept, where the sensitivity of input parameters is investigated and validated by the experiment. The methodology is applied to the heavyduty vehicle gearbox concept, where all inputs parameters are calculated similarly as in case of single-stage gearbox. The virtual prototypes enable to investigate influence of different input parameters on the design parameters, which are necessary at design phase. The surface normal velocity, which is related to noise prediction, can be evaluated. An experimental approach to validate the application on such high level of gearbox has not been performed yet.
