Abstract

The invention discloses a fault-tolerant vibrator. A first servo motor, two body valves, a second servo motor, a first gear, a second gear, a third gear, a fourth gear, a first rack and a second rackare included, wherein the first gear, the second gear and the third gear are sequentially engaged, the first rack and the second rack are engaged with the fourth gear, and the second servo motor is connected with the fourth gear. A valve body of each body valve is provided with an oil inlet and outlet port and a work oil port. The fault-tolerant vibrator further comprises a connector and a vibration cylinder. The connector is provided with two symmetric work oil ports and a vibration oil port. The two work oil ports of the connector are connected with the work oil ports of the two body valvescorrespondingly. The vibration oil port of the connector is connected to the vibrator. A double-motor drive and valve element and valve body direct matched manner is adopted in the vibrator, the vibration function can be achieved, and after a main drive part breaks down, a drive part still normally working is utilized for continuously finishing the vibration function.

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...
