Application of the Three-dimensional Coordinate System Method to the Adjustment of the Test Vehicle Position

Hong Nianle

Abstract：In recent years， with the continuous development of the economy， the automobile industry is also booming. According to Bitauto.com， the current per capita car ownership in our country has reached 0.141 [1]. This article mainly describes the improvement of the adjustment method of the relevant position of the car before the test during the car test. The test method also has related mandatory inspection standards. However， with the continuous development and innovation of science and technology， and the continuous research and improvement of test personnel， the requirements for quality and efficiency are becoming more and more stringent. Now it is aimed at the steering of its cars during passive safety tests. The adjustment of the pipe column and seat stroke improves the traditional adjustment method， and the article applies the three-dimensional coordinate system to the adjustment of the interior parts of the car.

Key words：passive safety， adjustment method， three-dimensional coordinate system， precision， efficiency

1 汽车转向管柱的调节

1.1 绪论

随着汽车保有量不断增加，道路交通事故也与之俱增，汽车给人类带来生活上的便捷，但也带来了人生灾难和财产损失，我国每年有大量的人在交通事故丧生，并且其比例远远高于其它发达国家！随着国人对汽车知识储备的提升，也逐渐由对车速、外观的关注转移到汽车安全上来[2]。我国本着对国民人身安全负责的态度，也一直不断加强对汽车安全质量的监督，以及汽车安全法规的不断改进，对车辆的安全性能越来越严格。我国目前乘用车的被动安全试验，国内的相关法规主要有GB11551-2014汽车正面碰撞的乘员保护，GB20071-2006汽车侧面碰撞的乘员保护，GB20072-2006乘用车后碰撞燃油系统安全要求，GB26134-2010乘用车顶部抗压强度以及C-IASI中国保险汽车安全指数等。
