Dual-Clutch Transmission Model Reduction Function

Abstract

This paper introduces a gearset model reduction function. It is an automated process that works for any type of gear set. The focus is on a dual-clutch transmission (DCT). Reducing the transmission from a multibody model to a table-based loss and inertia 1D rotational mechanics model leads up to a 70% decrease in simulation time. This performance improvement allows engineers to run a detailed physics derived model over the NEDC urban section in real-time or faster. Many customers have expressed the need for an automated model reduction tool. This paper aims at describing the methodology to create one. This function will be included in the next release of the VeSyMA – Powertrain library.
