Abstract

The invention provides an energy recovery vibration attenuating system for a cantilever frame, which is characterized in that the energy recovery vibration attenuating system has an energy recovery state and a vibration attenuating state and comprises a piezoelectric energy converting device and an energy storing device, wherein the piezoelectric energy converting device is connected with a cantilever frame and can carry out the corresponding conversion of energy according to an operating state of the energy recovery vibration attenuating system; and the energy storing device is connected with the piezoelectric energy converting device by a power converting device and can store or release the energy according to the operating state of the energy recovery vibration attenuating system.

Description

technical field [0001] The invention relates to the field of energy conversion, in particular to an energy recovery vibration damping device for a boom used in a concrete pump truck system and a corresponding energy recovery method and vibration damping method. Background technique [0002] In the commonly used concrete pump trucks at present, double oil cylinders are usually used to circulate material during the process of pumping concrete. During the process, there is a pulsating impact of the material supply, which will cause the boom to vibrate. This vibration is very harmful and will cause the end of the boom to be positioned. Inaccurate, boom cracking and many other problems. Boom vibration causes early fatigue damage to the boom, reduces its life, and also affects the construction quality, endangering the life safety of the operators. Effectively suppressing the vibration of the boom of the concrete pump truck has positive significance for improving the safety and ser...
