Abstract

The invention discloses a fault-tolerant vibrator, which comprises a first servo motor, two main valves, a second servo motor, a first gear, a second gear and a third gear meshed in sequence, a fourth gear and the fourth gear The meshed first rack and the second rack are connected with the second servo motor and the fourth gear. The valve body of the main valve is provided with oil inlet and outlet ports and working oil ports; the fault-tolerant vibrator also includes a connector and a vibrating cylinder. The connector is provided with two symmetrical working oil ports and a vibrating oil port. The two working oil ports are respectively connected to the working oil ports of the two main body valves, and the flutter oil port of the connector is connected to the vibrator. The vibrator is driven by dual motors and directly matched with the valve core and body, which can realize the vibrator function, and can continue to complete the dither function by relying on the drive part that can still work normally after the main drive part fails.

Description

technical field [0001] The invention belongs to the field of vibrators, in particular to a fault-tolerant vibrator. Background technique [0002] The electro-hydraulic vibrator is an excitation device that uses electro-hydraulic excitation technology to generate micro-vibration. The fault-tolerant control of the electro-hydraulic vibrator is to control the vibrating cylinder to continue to realize the vibrating function by relying on the driving part that can still work normally after the driving part fails. Among them, the flutter control valve is the core component of the electro-hydraulic flutter, and its performance and fault-tolerant control function directly determine the working performance and fault-tolerant performance of the electro-hydraulic flutter. [0003] Existing electro-hydraulic chatter technologies mainly include servo valve controlled electro-hydraulic chatter technology and rotary valve controlled electro-hydraulic chatter technology. The traditional e...
