The invention discloses a device for converting unidirectional vibration into orthogonal vibration. The device comprises a vibration input transfer plate, two oblique support elements and a vibration output end. The two oblique support elements are mounted between the vibration input transfer plate and the vibration output end, and vibration transmission directions of the two oblique support elements are not parallel to a vibration input direction of the vibration input transfer plate. During usage, vibration power is inputted to the vibration input transfer plate, different transmission responses are transmitted to the vibration output end via the two oblique support elements, and double-direction orthogonal vibration with certain phase difference is synthesized at the vibration output end, so that a function of converting the unidirectional vibration into the orthogonal vibration can be realized. The orthogonal vibration can be generated by a single vibration power source, and accordingly the device has the advantages of simple structure, stable performance and low cost. Besides, application requirements of orthogonal vibration tests can be met by the aid of the device, and the device further can be used for designing planar vibrating screens.
Description
technical field [0001] The invention relates to a vibration device, in particular to a device for converting unidirectional vibration into orthogonal vibration. Background technique [0002] Orthogonal vibration is often used in vibration testing. The current orthogonal vibration is mostly generated by dual power sources, that is, two vibration sources are used and their vibration power acts on a test piece at the same time. After the two different vibrations reach the test piece, two-way orthogonal vibration with a certain difference is formed. . Since this method requires two vibration power sources, it has a large volume, a relatively complex structure, high cost, and the problem of unstable performance due to inconvenient control. Contents of the invention [0003] The object of the present invention is to provide a device for converting unidirectional vibration into orthogonal vibration in order to solve the above problems. This device only needs one vibration power...
