Hyper-Element Technology: A Powerful Tool for Vehicle NVH Optimization

The Hyper-Element Technology is a simulation and analysis technique based on the finite element method, which can be used to finely analyze and optimize the NVH (noise, vibration, and harshness) problems of vehicles. By integrating multiple physical sub-models into a virtual model, the Hyper-Element Technology can effectively reduce model size and computational complexity, thus enhancing simulation efficiency and accuracy. In the development of whole-vehicle NVH, the Hyper-Element Technology is widely applied to the design and optimization of components such as the body structure, suspension system, and powertrain, enabling engineers to quickly and accurately evaluate various NVH indicators and implement corresponding measures to improve the vehicle's NVH performance. The application of Hyper-Element Technology not only greatly shortens the whole-vehicle development cycle and reduces costs but also improves the quality and competitiveness of vehicles. Firstly, this article introduces the basic principles and main advantages of Hyper-Element Technology. Secondly, the article uses Hyper-Element Technology to analyze the NVH of a whole vehicle, and verifies its application in the simulation of road noise and bushing sensitivity analysis. Finally, this article summarizes the application effects of Hyper-Element Technology in whole-vehicle NVH development and prospects for its future development direction. Through this research, it can be concluded that the Hyper-Element Technology is an efficient, accurate, and reliable tool for whole-vehicle NVH development, which will play an increasingly important role in future automotive manufacturing and NVH optimization.
