| 摘 要： | 利用有限元软件计算出柔性铰链结构参数与振动频率的训练样本,然后通过样本训练人工神经网络建立了柔性铰链结构振动频率与其结构参数的非线性映射关系,最后利用训练好的神经网络修正框架的结构参数以满足设计要求的固有频率。

| Abstract: | The specimen of the vibration frequency and the structural parameters of the flexure hinge are worked out through the finite element software. The nonlinear mapping relation between flexure hinge structural vibration frequency and structural parameters is built up by training the artificial neural network with specimen. The structural parameters are modified by the trained neural network in order to meet the design requirements of natural frequency. |
