Three psychophysical matching experiments were conducted to compare the perceived intensity of angular vibrations, in roll, pitch or yaw, with the perceived intensity of Z-axis translational vibrations. Seated subjects matched their perceptions of the intensity of Z-axis stimulus vibrations--at six frequencies from 2.5-8 Hz, at each of three intensity levels--by adjusting the intensity of angular response vibrations at the same frequencies. The results showed that the acceleration of the angular matching responses increased significantly as a function of both the frequency and the intensity of the stimulus vibrations. Since the stimuli were chosen from existing Z-axis equal intensity contours, the mean matching responses define equivalent contours for angular vibrations. Determination of relationships between translational and angular vibration is essential for the development of improved vibration exposure criteria applicable to complex vibration environments.
进行了三项心理物理学匹配实验，以比较横滚、俯仰或偏航角振动的感知强度与Z轴平移振动的感知强度。坐着的受试者通过调整相同频率下的角响应振动强度，来匹配他们对Z轴刺激振动强度的感知——在2.5至8赫兹的六个频率下，以及在三个强度水平中的每一个强度水平下。结果表明，角匹配响应的加速度随着刺激振动的频率和强度的增加而显著增加。由于刺激是从现有的Z轴等强度轮廓中选取的，平均匹配响应定义了角振动的等效轮廓。确定平移振动和角振动之间的关系对于制定适用于复杂振动环境的改进振动暴露标准至关重要。
