Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.
[0027] In practical applications, the transformer is the main vibration source in the converter cabinet. During the working process, the magnetostriction causes the transformer core to vibrate, and the vibration is transmitted to the converter cabinet and other components through the vibration damping pad, thus forming a pair of potential damage to pneumatic components. The kinetic energy caused by transformer vibration can be expressed as formula (2):
[0028]
[0029] In formula (2), T is the total kinetic energy of system vibration, is the system velocity column vector, for The transpose of , [M] is the system mass matrix.
[0030] At the i-th modal frequency, the total energy of the system is the sum of the energy obtained by vibration of all degre...
