| 摘 要： | 用加速度传感器测量法,测量压痕深度和冲量估算3种方法,在实验室内模拟条件下测定了3名健康男性伞兵的着陆冲击过载。结果表明,用3种方法测定的过载值有一定的差异,其影响因素可能与被试者的姿势、着陆场地等因素有关。

| Abstract: | The impact loads were determined by following three methods, measuring by an acceleration transducer, measering impact tracing depth on the ground at landing and evaluating impulse, the subjects were three healthy male parachuters. the experiments were perfomed under simulating conditions in the laboratory, the results showed that the impact loads during landing measured by these three methods were somewhat different. The factors which influenced these results were possibly related to the subjects' posture, the property of the landing ground and so on. It needs to be further studied under serious conditions. |
