Abstract

According to the whole vehicle road noise simulation benchmarking method based on the virtual road surface, the matching degree of virtual simulation and real vehicle testing is ensured, and a guarantee is provided for CAE-based vehicle road noise NVH problem investigation and performance optimization. According to the whole vehicle road noise simulation benchmarking method based on the virtual road surface, the reliability of a vehicle road surface vibration noise simulation calculation result can be effectively improved, the requirement that a simulation model is closer to a real vehicle state is met, the effectiveness of road noise NVH problem investigation and the correctness of an optimization direction are ensured, the vehicle model development fund and time cost are saved, and the research and development period is shortened.

Description

technical field [0001] The invention belongs to the technical field of automobile NVH, and in particular relates to a vehicle road noise simulation benchmarking method based on a virtual road surface. Background technique [0002] The advantage of using CAE technology in the vehicle product development process is that it can quickly check the typical performance problems of the design model and find the optimization direction, reduce the number of sample manufacturing and sample test rounds, save R&D costs and improve development efficiency. However, the reliability of the optimization results obtained through CAE depends on the reliability of the first version of the simulation results, and it is required that the first version of the simulation results and the prototype test results match as much as possible. When analyzing road vibration and noise problems based on virtual road surface technology, because the digital road surface and complex tire model are introduced on t...
