Description

technical field [0001] The invention belongs to the field of vibrating devices, and in particular relates to a stable vibrating device used for a towering equipment test bench. Background technique [0002] With the development of modern industrial technology, petrochemical and other fields have shown a booming situation, resulting in more and more various towers. The towering equipment will vibrate under the action of wind load, so there are more and more researches on the vibration of towering equipment. In addition to the commonly used simulation methods, many researchers often build a model test bench for the research object in equal proportions in order to obtain more accurate results. When this is the case, a stable external vibration excitation is required. device. However, wind tunnel experiments are too demanding, require a site, and are expensive; other excitation methods cannot provide stable excitation, and too large excitation equipment cannot be moved, and ex...
