- 中文摘要:
本文對戰車 (此處指主戰車,Main Battle Tank) 車前裝甲與砲塔裝甲提出設計準則,並利用有限制條件之最佳化設計方法,對設定條件下的車前裝甲與砲塔裝甲求出其最佳的幾何形狀與厚度分佈。 車前裝甲方面,以求得最大的有效厚度期望值為設計準則。在設定的長度與高度比之下,求其最佳之幾何形狀與厚度分佈,並討論重量與體積對裝甲防護力的影響。對砲塔裝甲設計,則分兩部分討論:第一部分以偏心圓或橢圓模擬砲塔受到敵方砲火攻擊的概率分佈曲線,以求得砲塔對此概率分佈之最小投影面積期望值為設計準則,設計出最佳的砲塔外形;第二部分則將求出之外形,按照各部分裝甲所面臨的被攻擊概率,安排其厚度之分佈與斜角之大小。由上述兩部分之探討可得到完整之最佳砲塔裝甲設計。本文求得上述兩種最佳裝甲設計之結果,並與現有之戰車外形相比較。 本文所得之結論,說明了若有充分的敵方反戰車武器資料,即可利用本文提出之方法求得最佳的裝甲設計。
- 英文摘要:
Design criteria of the front armor and theturret armor of the main battle tank (MBT) havebeen presented and discussed. The InteriorPenalty Function Optimization Method was usedhere to determine the constrained optimumshape and thickness distribution. The design policy of the front armor is toget the largest expectation of effective thickness.For specified lenght-to-height ratios, excellentresults have been obtained. The influence ofthe weight and the volume to the protectioncapability was figured. The optimum design ofthe turret armor was performed in two stages.In the first stage, an eccentric-circle or anelliptical distribution was used to simulate theprobability density function of being-attackedfor the turret. The design policy to determinethe optimum geometric shape of the turret isto get the smallest expectation of projectionarea according to the probability density func-tion. From results of the first stage, the opti-mum slope and thickness of each part of theturret armor can then be determined by itsprobability of being-attacked. From the methods and the results presentedin this work, then optimum armor design canbe determined provided that sufficient informa-tion about hostile anti-tank weapons is available.
