汽车碰撞测试靶向移动平台研制与试验

Development and test of a mobile platform for vehicle collision test

通过搭建开发一辆汽车碰撞测试软目标靶向移动平台系统用于评估这项碰撞技术。可用于汽车碰撞测试环境,整个系统包括测试平台机械结构、控制系统、导航系统和远程控制系统控制。其机械结构可耐汽车碾压,整机通过差分GPS定位实现位置系统闭环控制,利用位置指令与参数调节实现移动平台的姿态矫正和速度控制。最终确保移动平台具有以规定速度、按照规定路线行驶,最终达到指定目标位置。同时,在行驶过程中具备能够完成碰撞试验的能力。

A soft target mobile platform system for vehicle collision test is developed to evaluate the collision technology.It can be used in vehicle collision test environment.The whole system includes mechanical structure,control system,navigation system and remote control system.Its mechanical structure can withstand the rolling of automobiles.The whole machine realizes closed⁃loop control of position system through differential GPS positioning,and realizes attitude correction and speed control of mobile platform by using position command and parameter adjustment.Finally,ensure that the mobile platform can drive at the specified speed and route,and finally reach the specified target position.At the same time,it has the ability to complete the collision test in the driving process.
