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。
Using human ejection test data to establish a mathematical model of human dynamic characteristics (referred to as human mathematical model). Dynamic response analysis of the model can solve some of the catapult-related ergonomic issues. According to the human body’s maximum dynamic overshoot, combined with vertebral strength to determine the limits of human tolerance ejection acceleration. From a protective point of view, the impact of the cushion on the body force and the characteristics of the human body’s response to the time required to analyze the thickness of the cushion must be very thin. Also put forward to improve ejection power and determine the test system performance indicators. Using the model for catapult practice can reduce human trials and is extremely beneficial to human safety and development and production.
