降落伞试验中假人姿态对过载测量影响的研究

The study in the parachute test overload is affected by posture

降落伞空投试验中假人姿态不易控制,随机性较大,从而使假人开伞过程中在各向分力的作用下产生复杂的翻滚运动,导致假人质心处安装的过载传感器测取的过载数据离散性较大。文中介绍了一种新的测试方案,并进行空投试验,对测取的包括假人角速度、假人三向分力和假人多点过载等多项数据进行综合对比分析,研究假人姿态变化对过载测量的影响特性。

In the parachute drop test dummy-people,s posture is not easy to control, randomness, thus dummy-people complex movement in the process of opening an umbrella by each component, lead to big discreteness in the data of overloading sensors at the center of mass. This paper introduces a kind of new test and drop test, including acquire data of angular velocity, data of three-way force and data of multipoint overload, and analysis them, to study the effect of dummy-people,s posture change on the overload measurement features.
