Abstract: Based on the aerodynamics optimization request of a vehicle, this paper raised a new design for spoiler around the front wheel area. A related construction design scheme and material seletion was provided, which can further reduce the vehicle wind drag and improve the driving mileage. Through the analysis of the actual working conditions, a single bench test method is designed to guide the structural optimization and process improvement of parts, which provided a guidance to structure and process optimization. Through the comparison between test rig and vehicle test, this test method using single part was verified, which can shorten the development cycle and reduce the cost. The new spoiler construction and test design could provide a reference for the vehicle aerodynamics optimization.
