-
摘要: 建立了鸟体模型和风挡玻璃破坏准则,形成了一套完整的风档鸟撞动响应分析方法.并对某风挡进行了鸟撞动响应分析,得出了鸟的运动轨迹以及风挡玻璃的鸟撞临界速度,经与实验结果比较,两者吻合较好.Abstract: This paper is to establish the bird body model and windshield glass destroyed criteria so as to form a complete set of windshield bird strike dynamic response analysis method.It is also to perform the bird strike dynamic analysis for some windshield to find the bird motion projectile,windshield displacement,stress strain response and the bird strike critical velocity of windshield,which is coincided with the test results after comparison.
