Delphi to Present Simulation Method Enabling More Efficient Design Process and Reduced Development Time
Thermal Systems engineer to speak at VTMS conference next week
PARIS – Delphi Automotive is working to improve the noise comfort for vehicle passengers and pedestrians around the vehicle through virtual product simulation tools, and the company will highlight this work at the upcoming Vehicle Thermal Management Systems Conference and Exhibition being held May 15-19 at the Heritage Motor Center, Gaydon, Warwickshire, U.K.
Mélanie Piellard, product development and analysis engineer, Delphi Thermal Systems, will present a paper titled “Application of Hybrid Computational Aeroacoustics Method to An Automotive Blower,” at 9:00 a.m. on Wednesday May 18, as part of Session 7B on External and Internal Component Flows. Piellard authored the paper along with Bruno Coutty, senior noise and vibration engineer, Delphi Thermal Systems.
“The highly-competitive automotive environment requires OEMs to introduce new car models in a short time and in a cost-effective way. Delphi works to develop methods which can help simulate acoustic behavior of thermal systems under real-world conditions,” said Piellard. “This process enables an accelerated and more design of thermal components while helping to reduce costs during development.”
The paper details how a hybrid method of aeroacoustic noise computation is applied to investigate the noise radiated by an automotive HVAC blower in an effort to develop a simulation tool as part of the general trend towards virtual product development.
“In order to take rotating surfaces into account, a new type of simulation had to be developed. Prior to this new tool/process, we were analyzing the noise level through empirical methods,” Piellard said. “Acoustic-simulation results exhibit the same trend as experimental measurements performed under identical conditions. It allows identifying improvement paths for the simulation method. The new simulation improves the understanding of noise generation in the product and decreases development time and cost.”
