| 摘 要： | 建立了人椅系统运动模型，针对人体结构特点，建立了飞行员上肢3刚体7自由度数学模型．采用Kane方法建立了人体上肢动力学模型，计算了上肢各环节在弹射救生过程中相对转角等，计算结果表明身体上肢甩打过程短暂，整个甩打过程在0．4～0．5s甚至更短的时间内，上肢各关节的转角及由此引起的关节力、力矩即可达到人体的耐受极限，仿真结果显示上肢运动的特征有明显的“鞭打运动”。通过CATIA二次开发方式，对飞机弹射救生过程人体动力学响应特征进行可视化仿真，使设计人员能够直观的获得各种弹射情况下人椅运动规律，提高设计效率？

| Abstract: | The kinematics model of escape system was established. A 3- segment mathematical model of pilot＇s upper limbs and a dynamics model based on Kane＇s equation were developed. It is found that the upper limbs move transitorily and arrive at the extreme limit of joint angle and imposed force no more than 0.4s. The result shows that the upper limbs act as whiplike. Simulation based on redevelopment of CATIA facilitates the designer a way in which status of man-seat system can be directly acquired and effectiveness in design can be promoted. |
