汽车碰撞试验橡皮绳弹射速度回归统计分析与预测

清华大学汽车碰撞实验室利用橡皮绳弹射加速试验车进行碰撞试验。用线性回归统计的方法预测橡皮绳拉伸长度,精确地控制了开环状态的试验车的碰撞速度。这种橡皮绳弹射试验速度控制方法克服了由于阻力、环境温度等因素造成的影响,避免了造成巨大损失危险。同时对目前国内采用同类试验方法的试验室有一定的参考意义。

Speed Regression Analysis and Statistical Forecast in Vehicle′s Impact Test

Elastic rope is used to speed up the test vehicles in the Vehicle mpact Laboratory of Tsinghua University. By forecasting the length of the elastic rope with linear regression anslysis, test vehicle′s speed can be controlled acctrately. This method avoids the influence of resistances and cirumstance temperature, leading to escape from magnitude loss. And the method would be universal to the laboratories who is in use of this speed up method.
