摘　　要：采用白噪声激励信号,在2．0-35．0 Hz频率范围内进行大样本垂直振动试验,分别研究了卧姿中国 人体不同状态(自由、约束)下、不同部位(胸部、腹部以及头部)的激励点加速度阻抗特性,分析了机械振动对卧 姿人体的输入特性,试验分析结果可用于卧姿人体垂直振动模型的建立。Through a mass of vertical mechanical vibration tests under white noise excitations in the 2. 0-35. 0 Hz frequency range, the driving point acceleration impedance curves of the chest, the abdomen, and the head of the supine Chinese human body in both free state and restriction state are obtained. The vibration input characteristics of the supine human body are analyzed. The results are of great benefit to obtaining the driving point acceleration impedance model of the supine Chinese human body.
