Bullet powder distribution uniformity evaluation method based on triangle subdivision

Abstract

The invention discloses a triangular subdivision-based bullet powder distribution uniformity evaluation method, which comprises the following steps of S1, obtaining bullet powder distribution coordinates, setting the number of bullet powder to be n, and measuring the coordinates (xi, yi) of the n bullet powder; s2, triangular subdivision is carried out on sub ammunition distribution, and a triangular network is constructed; s3, determining whether a scattering blind area exists or not, if the scattering blind area exists, removing the scattering blind area to obtain m effective triangles Tj, and if the scattering blind area does not exist, directly performing the next step; s4, calculating the area S (Tj) of each effective triangle, calculating the total distribution area Stotal of the whole ammunition and # imgabs0 #; S5, calculating the distribution uniformity U, wherein the closer the value of # imgabs1 # U is to 1, the more uniform the ammunition is distributed, and the closer the value of # imgabs1 # U is to 0, the more non-uniform the ammunition is distributed. The evaluation method can be used for universally and quantitatively reflecting the distribution uniformity of the ammunition, conforms to the intuition of people, and is suitable for evaluating the uniformity of the ammunition with different distribution characteristics.
