大灯碎片运动力学参数的试验研究
Experimental Calibration of Mechanics Parameters of Headlamp Splinter Motion Law
【摘要】 基于广义抛物理论模型,以汽车大灯碎片为例,提出了广义抛物模型的两个重要参数(角度和速度损失系数)的测试方法,并利用数理统计方法获得它们的统计结果,使得广义抛物模型更接近实用。
【Abstract】 Based on the generalized modeling of the throwing object trajectory, the glass spl inter of headlamp is taken under the consideration as an example. The author has developed the method of testing two important parameters (the angle and velocity loss coefficients) for the generalized formula of the throwing motion.The two parameters are determined by the theory of the mathematical statistics so that the generalized formula may be put into use.
