A series of tracking experiments under vibration has been carried out on the AMRL/BBV shaker facilities covering three axes of vibration with sinusoidal and random waveforms and different control stick configurations. Based on this and other data, a lumped-parameter biomechanical model has been evolved to suit the needs of aircraft control system designers for the new generation of low-altitude, high-speed bombers and highly maneuverable fighters. This paper shows that measured vibration feedthrough to hands and head can be adequately described by this model when linearized about the appropriate configuration of display, posture, and control. The model includes effects of: semisupine torso; sliding hip, plus rocking chest supported on a compliant buttocks/seat; head bobbing on an articulated neck; upper arm and forearm links plus grip-interface compliance, driven by an active neuromuscular system; elbow rest (optional); and stick "feel system" dynamics. Examples are given of the model's application to predict effects of: a 65 degrees semisupine seat, apparent impedance increase of a control stick under pilot control, and a sliding arm rest.
在AMRL/BBV振动试验设备上进行了一系列振动跟踪实验，实验涵盖了振动的三个轴，采用了正弦波和随机波形以及不同的操纵杆配置。基于这些数据和其他数据，开发了一个集总参数生物力学模型，以满足飞机控制系统设计师对新一代低空、高速轰炸机和高机动性战斗机的需求。本文表明，当围绕显示器、姿势和控制的适当配置进行线性化时，该模型可以充分描述测量到的手部和头部的振动传递。该模型包括以下影响因素：半仰卧躯干；滑动臀部，加上支撑在柔顺臀部/座椅上的摆动胸部；铰接颈部上的头部摆动；由主动神经肌肉系统驱动的上臂和前臂连杆以及握把接口柔顺性；肘部支撑（可选）；以及操纵杆“感觉系统”动力学。给出了该模型应用的示例，以预测以下方面的影响：65度半仰卧座椅、飞行员控制下操纵杆的表观阻抗增加以及滑动扶手。
