The invention discloses a cavitation-controllable intelligent steering rudder plate device for an amphibious vehicle, belongs to the technical field of amphibious platforms, and can realize intelligent monitoring of cavitation and torque of a steering rudder surface and improve the effective control precision of cavitation. The device comprises a hydrofoil A, a hydrofoil B, a piezoelectric sensor, a sealing rubber pad, a connecting shaft, a six-axis force sensor, a rotating shaft, a high-pressure jet flow controller, a transmission structure, a jet flow connector and the like. The piezoelectric sensor is adopted to monitor the pressure change of the control surface in real time, whether cavitation occurs or not is judged based on pressure data, the pressure of a low-pressure area is increased through porous high-pressure jet flow, and cavitation suppression is achieved. The change condition of dynamic characteristic data of the steering rudder can be measured in real time through the six-axis force sensor, feedback control is timely and effectively provided, and the intelligence of the steering rudder is greatly improved.

    本发明公开了一种空化可控的两栖车智能转向舵板装置,属于水陆两栖平台技术领域,能够实现转向舵面空化和力矩的智能监控,提高空化有效控制精度。该装置包括:水翼A,水翼B,压电传感器,密封胶垫,连接轴,六轴力传感器,转轴,高压射流控制器,传动结构,射流接头等。采用压电传感器可实时监测舵面压力变化,基于压力数据判定是否发生空化,采用多孔高压射流增大低压区压力,实现空化抑制;通过六轴力传感器可实时测量转向舵的动力特性数据变化情况,及时有效地给予反馈控制,大大提高了转向舵的智能化。
