乘用车前后端保护装置测试设备的开发

Front and Rear Protective Devices Test Equipment Development for Passenger Cars

为研究乘用车前后端保护装置的重要性及测试设备的发展现状,以GB 17354—1998要求为基准,采用平行四边形刚性悬吊,设计时充分考虑结构和安全因素,开发出前后端保护装置测试设备。与主机厂开展沟通交流,对设备控制精度和试验流程达成统一共识,测试证明:设备试验精度高,具备评估乘用车前后端在发生轻度碰撞时该车的损伤程度,以及判断该车是否满足国家法规要求的能力。另外,测试设备预留接口,具备验证待检车是否满足3C规则的扩展内容及ECE29法规要求的能力。

To study the importance of front and rear protective devices for passenger cars and the current status of equipment＇s inspection, according to GB17354-1998 national standards, test equipment of front and rear protective devices is developed, whose design used a parallel quadrilateral rigid suspension and took full account of the structure and security factors. After communication with automobile factory, a consensus is reached on protective devices control accuracy and test process. Evidence shows that the test equipment with high test precision can accurately detect protective bumper capability to vehicle, evaluate damage degree when low- speed Crash happened, and judge whether the test vehicle meets the requirements of GB Standards. In addition, the test equipment reserves interface, and is able to verify whether vehicles meet 3C extended content and ECE29 requirements.
