A tactile feedback device of a piezoelectric ciliary body beam is presented. In order to investigate the relationship between the sizes of the ciliary body beam, the position of the piezoelectric ceramics plates and the frequency of the excitation signal, the electromechanical coupling dynamic model of the piezoelectric ciliary body beam is established. According to the boundary conditions and the continuous conditions, the natural frequencies and mode functions are solved. The results show that the ciliary body structure has little effect on the natural frequencies of the beam; the natural frequencies of the ciliary body beam are mainly affected by the length and width of the beam. According to the calculation results, brass is more suitable as a material for the beam. The coupling dynamic model and calculation results will provide a theoretical basis for forced vibration analysis of the beam and the establishment of the haptic device roughness model.

提出了一种压电睫状体梁的触觉反馈装置。为了研究睫状体梁的大小，压电陶瓷板的位置和激励信号的频率之间的关系，建立了压电睫状体梁的机电耦合动力学模型。根据边界条件和连续条件，求解固有频率和模函数。结果表明，睫状体结构对光束的固有频率影响很小。睫状体梁的固有频率主要受梁的长度和宽度影响。根据计算结果，黄铜更适合作为梁的材料。
