利用虚拟激光技术评估在实际使用的激励状态下后视镜的性能

Objective Assessment of Door-mirror Performance under In-service Excitations Using the Virtual Laser Technigque

近几年来,汽车的舒适性问题变得越来越重要。特别是在行驶条件下,汽车内外后视镜的性能会影响反射后的视图,并影响驾驶员的视觉。因而,工程师通过实际使用中后视镜的振动开发了量化视觉感知的测量技术。这个项目采用了伊迪达机动车技术有限公司开发的一种使用虚拟激光技术的新颖方法。主要目的是研究四种不同的车门后视镜在实际使用中的振动。此外还讨论后视镜的设计和将来如何进一步提高他们在振动中的性能。

Vehicle comfort issues have become increasingly important in recent years. In particular, the performance of interior and exterior vehicle mirrors in driving conditions can affect the reflected image perceived by the driver. Therefore, engineers have developed measurement techniques to quantify the visual perception produced by the in-service door-mirror vibrations. The main aim of this work was to investigate the in-service door-mirror vibrations of four different door-mirrors, using the virtual laser technique, a novel technique developed by Applus ＋ IDIADA. Furthermore, some considerations are taken about the door-mirror designs and the future work needed to improve them in terms of vibration performance.
