| Abstract: | Based on the dynamical theories for rigid-flexibility coupling systems,a concrete pump truck boom is simulated on damping attenuation properties in the case of rotary starting and braking.Further studied on the boom yaw vibration mechanism,a control strategy is proposed to for steady braking and yaw vibration reduction.By the means of testing,the control strategy feasibility is validated.Therefore,this approach provides a novel method for safety control on similar rotary-braking construction machinery. |
