摘　　要：随着汽车电子技术的发展,汽车电动尾门在很多高端车型中的应用越来越普遍,电动尾门不仅提高了汽车使用者的便利性,也很好地提高了产品使用的安全性。为了探究电动尾门开关门耐久试验,首先对电动尾门系统控制原理进行了分析,并建立了电动尾门在不同路面坡度下的力学模型,力学模型表明车辆在不同位置状态对电动尾门的受力具有较大影响。搭建汽车电动尾门开关门耐久试验装置,运用可编程逻辑控制器进行逻辑控制,并与总线仿真系统进行通信,实现对电动尾门的过程控制,再运用光电传感器和高速脉冲模块可以精准地获取电动尾门开关门的速度。试验系统采用全闭环的PID逻辑控制策略,可以精准地控制汽车电动尾门手动开关门的速度。在不同使用工况下,对电动尾门进行失效模式研究,为电动尾门系统的设计和优化提供数据支持。With the development of automobile electronic technology,the power lift gate system not only improves the convenience of automobile users,but also improves the operation safety.In order to explore the slam durability test of the power lift gate,firstly,the control principle of the power lift gate system is analyzed,and the mechanical model of the power lift gate under different slopes is established.The mechanical model shows that the vehicle in different positions has a greater impact on the force of the power lift gate.A slam durability test device for the power lift gate is built.The PLC is used as logic control unit;also communicate with the CAN-bus simulation system to realize the process control of the power lift gate.The photoelectric sensor and high-speed pulse module can accurately obtain the slam speed of the power lift gate.The test system adopts the closed-loop PID logic control strategy,which can accurately control the manual slam speed of the automobile lift gate.Under different working conditions,the failure mode of power lift gate is studied to support the design and optimization of power lift gate system.
