对某类飞行器,点火前1-2秒到点火后3-4秒,是力学环境的最重要采样时段。无线测量常因信号失真、规律异常、离散性过大,不能得到满意的结果。在飞行器外表面直接敷设电缆,飞行时顺序剥离,测量结束时实现机械式安全分离的有线测量方法是经济有效方法。力学分析的任务,是给出电缆固定于飞行器表面的胶合力数据;起剥点和分离点的最优位置;剥离力和分离力的大小和最优方向,本文介绍了力学分析的一般方法。文末附有应用实例并作了讨论。
For some aircraft, 1-2 seconds before ignition to 3-4 seconds after ignition, is the most important sampling period for the mechanical environment. Wireless measurement often due to signal distortion, irregularities, discreteness is too large, can not get satisfactory results. It is a cost-effective method to lay cables directly on the outer surface of an aircraft, to peel them sequentially in flight, and to perform a mechanical safety separation at the end of the survey. The task of mechanical analysis is to give the data of the gluing force of the cable fixed on the surface of the aircraft; the optimum position of the peeling point and the separating point; the size and optimal orientation of the peeling force and separation force. This paper introduces the general method of mechanical analysis. The end of the text attached with examples and discussed.
