飞行员在飞行中会面临各种复杂载荷,这些复杂载荷会给飞行员肌骨、血液循环等系统产生复杂生理影响，从而导致飞行员损伤。生物力学主要研究生物医学中的力学问题及力的生物学效应。航空生物力学是研究人体在航空动力环境中生理变化规律及其防护措施的学科, 其主要研究内容包括：冲击载荷对人体的损伤及其防护；持续性载荷对人体的生理影响及其防护或对抗；振动与噪声对人体的生理影响及其防护等。

Pilots are usually under various different mechanical loads during flights, which can affect their musculoskeletal and cardiovascular system and even bring them injuries. Biomechanics mainly studies the mechanics and mechanobiology in medicine and biology. Aviation biomechanics studies the physiological response to different complicated mechanical loads during flights and the countermeasures. The research fields of aviation biomechanics include: mechanical loads on human body injury and related countermeasures, durative loads, vibration and noise on the physiological effects of human body and related comtermeasures, etc.
