摘要
利用人体弹射试验数据建立起人体动力学特性的数学模型(简称人体数学模型)。模型的动态响应特性分析可以解决一些与弹射有关的人体工程学问题。根据人体的最大动态超调,结合椎骨强度可确定人体耐受弹射加速度的限度。从防护角度出发,分析座垫对人体受力的影响和人体响应的时相特点而要求座垫厚度必需很薄。还提出改善弹射动力和确定测试系统性能指标的依据。将模型用于弹射实践可以减少人体试验,对人体安全和研制生产都极其有利。
Mathematical model of human body has been developed based on ejection tests. Combining vertebral breaking strength with dynamic response characteristics of the model, human's tolerance limits of acceleration have been determined. The model is used to study the effects of ejection cushion and !a thin cushion is recommended for avoiding vertebral injury. How to improve the ejection propeller and to determine the requirements of acceleration measuring system are discussed. To put the mathematical model in practice is convenient, safe and useful for human being.
