| 摘 要： | 为了研究两半正弦正负相组合波形作用下人员抛离问题，以LS-DYNA程序为工具，计算了立姿人体抛离时程曲线。考虑了人体阻尼影响，比较了人体抛离速度与已有公式的计算结果，指出了已有公式的合理适用范围。计算结果和已有经验公式的结果吻合较好。

| Abstract: | The LS-DYNA finite element program was applied to the research of human body kick-off under the combined wave of double semi-sine wave with positive and negative value. The kick-off curve of human body was calculated by considering the effect of body damper, and the velocity of kick-off was compared with the previous formula in reference. Eventually the reasonable application range of the formula was worked out. The result of calculation accords well with the experience formula. |
