中文摘要 | 本研究將人體模擬成15個剛體的人體坐姿模型,並以不同的連接機構連接而成多剛體系統,利用肯氏(Kane)及休士頓(Huston)發展的多體動力學分析理論,推導出人體數學模型受到外力作用時的肯氏動力學方程式,並建立一個三度空間人體衝擊動力學模型,並配合自行撰寫的人體運動的電腦計算分析程式,針對飛行員於彈射逃生時人體頭部的動態反應模擬與分析。為了驗證所建構人體衝擊動力學模型的準確性,模擬的動態響應並與Perry之實驗數據進行比較,藉以探討飛行員緊急逃生彈射的安全性,以評估彈射時的各種載荷是否會造成飛行員的損傷,並為彈射座椅的最佳化設計提供依據。 |
英文摘要 | This study develops a three-dimensional 15-segment seated human body model which the segments interconnected with joints. The dynamical equations of motion of the mechanical structure are based on Kane’s equations as formulated by Huston and Passarello. A three-dimensional human impact dynamics model is established. These equations are then coded into a computer program and solved using fourth-order Runge-Kutta methods. This study focuses on the dynamic response of the pilot’s head and neck during ejection events. To confirm the accuracy of the proposed human dynamics model, the current results are compared with Perry experimental data. The results obtained herein contribute to efforts to analyze pilot escapes injury and optimize ejection seat design. |
