AI Technical Summary

Technical Problem

The existing pump truck boom vibration isolation system has low efficiency and high energy consumption, making it difficult to effectively avoid structural damage and safety accidents caused by boom resonance.

Method used

By installing a vibration isolation device on the boom and using the movement of the counterweight to change the modal frequency of the boom, the pumping frequency is kept away from the modal frequency range of the boom. The modal frequency of the boom is determined by modal analysis and the position of the counterweight is controlled to change the modal frequency of the boom.

Benefits of technology

The efficiency of boom vibration avoidance is improved, the risk of safety accidents caused by resonance is reduced, and the energy consumption of the vibration avoidance system is reduced.

Abstract

The present application discloses a method, controller, vibration isolation system and storage medium for controlling boom vibration isolation. The method includes: obtaining the pumping frequency, boom inclination data and counterweight position information at preset time intervals, as well as obtaining the boom's inherent parameters and counterweight mass information; determining the boom's modal frequency based on the boom's inclination data, boom's inherent parameters, counterweight position information and counterweight mass information; judging whether the pumping frequency is within the vibration frequency range of the boom's modal frequency; and when the pumping frequency is within the vibration frequency range of the boom's modal frequency, controlling the vibration isolation device on the target boom to change the boom's modal frequency so that the pumping frequency is not within the vibration frequency range of the boom's modal frequency. The present application changes the boom's modal frequency through the vibration isolation device, thereby achieving the purpose of reducing the possibility of boom resonance while improving the vibration isolation efficiency and reducing the energy consumption of the vibration isolation system.
