摘要：

为降低两轮车与汽车发生碰撞造成的伤害,提出一套基于单牵引轨道实现两轮车与机动车联动碰撞的测试方案。在该方案中,以自行设计的、压缩空气为动力源的简易驱动机构,来实现两轮车不同角度、不同速度的运行模式;在牵引系统拖动机动车行进过程中,通过碾压特定位置的带状开关,来控制两轮车驱动机构的启动时机,实现特定运行状态下的两轮车与机动车在设定位置发生碰撞。该方案可模拟两轮车与机动车前、后、侧围等任意位置的碰撞形式,且撞击精度小于±25 mm。因而,实现了在单牵引轨道上两轮车与机动车联动碰撞的高精度试验能力。这为道路弱势群体（VRU）保护技术研究提供一种基础测试方法。

Abstract:

A linkage impact test method was designed based on single drag rail to reduce the damages of two-wheeler riders impacting with car. The test method kept two-wheeler’s motion states at different angles and different speeds with an ease driving mechanism powered by compressed air. The trigger time of launch a two-wheeler was controlled by rolling compaction a switch tape of the running car at an accuracy position, it made the impact between two-wheeler and vehicle was in the setting condition. This method can simulate the impact at any sides of car with a two-wheeler, and the position accuracy was less than 25 mm. Therefore, the high-accuracy test capability for the two-wheeler-to-car linkage impact test on single drag rail will prove a basic test method to the research on Vulnerable Road User (VRU) protection technology.

Key words: two-wheelers, vehicles, linkage impact, vulnerable road user (VRU) protection
