交通事故中抛撒出的玻璃碎片的抛距为交通事故鉴定提供了有用的信息。多年来，一些研究者对交通事故抛撒物的抛撒机理进行了研究，并对玻璃碎片抛撒距离进行了大量的试验。如果玻璃碎片的抛距和玻璃破碎的抛出速度关系已知，就能够确定玻璃破碎的地点或车速。因此，本文首先对玻璃碎片的抛撒运动机理进行了理论分析，在此基础上建立玻璃碎片运动的数学模型，然后，对此模型进行了改进，使其能够直接应用于交通事故的鉴定。借助于已有的试验数据，利用最小二乘法和优化方法确定改进后的数学模型参数。此外，还对这种模型应用的可能性进行了探讨。
The throw-away of glass fragments thrown out in traffic accidents provides useful information for the identification of traffic accidents. Over the years, some researchers have studied the mechanism of disaggregation of traffic accidents and conducted a large number of experiments on the throw distance of glass fragments. If the relationship between the throw distance of the glass shards and the throwing speed of the broken glass is known, the location or speed of the broken glass can be determined. Therefore, in this paper, the disintegration mechanism of glass fragments is theoretically analyzed. Based on this, a mathematical model of the movement of glass fragments is established. Then, the model is improved so that it can be directly applied to the identification of traffic accidents. With the help of the existing experimental data, the least squares method and optimization method were used to determine the improved mathematical model parameters. In addition, the possibility of applying this model is discussed.
