【摘要】 高速公路货车被追尾事故时有发生,常要求计算被追尾货车车速,尤其对超载货车的车速计算。鉴于此,本文对常用于此种事故进行车速计算的功率平衡方程做了较深入的研究,探讨了功率平衡方程中容易产生应用误差的参数对最终车速计算结果的误差影响程度。更多还原

【Abstract】 On the highway,vehicle rear-end collision occurs from time to time. The calculation of the speed of rear-ended goods vehicles is necessary,in particular,the speed of overloaded goods vehicles. In view of above,this paper made a deep research on the power balance equation which usually used in calculating the velocity of vehicles for such accident,and discussed the effect of the parameter which consists in power balance equation and easy to cause the application error on the final velocity.更多还原
