The invention discloses a multi-freedom-degree electro-hydraulic vibrating table. The vibrating table comprises a mechanical part and a hydraulic system part. The mechanical part comprises four vertical vibrating devices and four horizontal vibrating devices. The four vertical vibrating devices are symmetrically disposed at end parts of a vehicle body, wherein each end of the vehicle body is provided with two vertical vibrating devices. Two horizontal vibrating devices are disposed at one end part of the vehicle body, and the other two horizontal vibrating devices are disposed on one side surface of the vehicle body. The hydraulic system part comprises a power source hydraulic system, four vertical vibrating hydraulic systems, and four horizontal vibrating hydraulic systems. The power source hydraulic system is connected with the vertical vibrating hydraulic systems and the horizontal vibrating hydraulic systems. The vertical vibrating hydraulic systems are connected with vertical hydraulic cylinders, and the horizontal vibrating hydraulic systems are connected with horizontal hydraulic cylinders. The power source hydraulic system drives the vertical vibrating hydraulic systems and the horizontal vibrating hydraulic systems to work independently, enables the corresponding hydraulic cylinders to generate excitation, and achieves the vertical, horizontal and inclined vibration of the vehicle body through the combination with the mechanical part. The vibrating table is compact in structure, and is facilitates the control.
Description
technical field [0001] The invention belongs to the mechanical field, in particular to a multi-degree-of-freedom electro-hydraulic vibrating table capable of realizing multiple working conditions of vertical, horizontal and inclined. Background technique [0002] The impact of vibration on electromechanical products cannot be ignored. It is extremely important to conduct vibration tests. However, due to the high cost, vibration tests in real environments are not feasible. The reliability and dynamic strength of equipment can be identified by simulating the vibration environment on a vibration table. has been used as an effective tool. The electro-hydraulic vibration table is widely used in the market due to the advantages of small size, large output, high precision and quick response, but it has extremely high requirements for control. Contents of the invention [0003] The technical problem solved by the present invention is to provide a multi-degree-of-freedom electro-h...
