Abstract

In the previous paper (van der Seijs MV, Harvie JM, Song DP, Road noise NVH: embedding suspension test benches in NVH design using Virtual Points and the TPA framework. In: Proceedings of the thirty-ninth international modal analysis conference, 2021), we presented the feasibility of using a tire noise test bench in the engineering of full-vehicle NVH. Road noise at the driver’s ear was accurately simulated with blocked forces obtained using several different methods: with the suspension on two test benches (one rigid and one compliant) and in the full vehicle. All methods produced accurate results, using virtual points in DIRAC to ensure compatibility between the various test assemblies.
In this paper, we further investigate the capabilities of the framework using interface forces instead of blocked forces. Several methods are used to calculate interface forces: a matrix inverse method, a mount stiffness method, and with interface forces derived from blocked forces. Results are evaluated for the simulation of road noise at the driver’s ear in the vehicle.
