摘　　要：本文提出了一种测量飞行器风挡鸟撞击模拟试验中风挡变形的时间历程的新技术。采用一只测量基准，使两台摄像机的拍摄方向相互垂直，且两台高速摄影机的摄影范围均包含所需测量的区域。试验结果表明该方法的精度是比较高的。A new technique for measuring the time history for 3-dimensional displacement of points on the inside surface of an aircraft transparancy during a simulated impact of a bird has been developed. In this method, a measurement datum and two high speed cameras are used. The cameras are positioned perpendilar to each other and contain a commom field of view of insterested. Some examples are discussed. Very accuate results are obtained.
