本文介绍了猴体随机振动、正弦扫频振动和锤击振动实验方法和结果。４只４．０～５．５ｋｇ的猴承受坐姿头尾向振动，测量了猴头，胸、腹、肝、胃、腰椎和骶骨的加速度响应，求得相对台面和骶骨的传递函数。结果表明猴体动力特性在一定条件下可近似看作单自由度或双自由度系统，而且共振频率随着振动Ｇ值增大而减小，得到了在较大振动范围内猴体刚度非线性明显而阻尼非线性不明显的结论。为猴体建立非线性动力学模型提供了数据，可供人体振动防护研究参考。
In this paper, we introduce the experimental methods and results of random vibration, sinusoidal swept frequency vibration and hammer vibration of monkey body. Four 4.0-5.5 kg monkeys were subjected to head-to-tail vibration, and the acceleration responses of hericium, thorax, abdomen, liver, stomach, lumbar and sacrum were measured to obtain the transfer function between the mesa and the sacrum. The results show that under certain conditions, the dynamics of a monkey body can be regarded as a one-degree-of-freedom or a two-degree-of-freedom system, and the resonant frequency decreases with the increase of the vibration G value. The nonlinearity of the monkey body stiffness Obvious and damping nonlinearity is not obvious conclusion. Provided the data for the establishment of nonlinear dynamic model of the monkey, which can be used as a reference for human body vibration protection research.
