Damped vibrations of telescopic crane boom
Abstract eng: In this paper, the influence of different kinds of damping on vibrations of truck-mounted crane boom is presented. Vibration energy dissipation during changing the boom radius is caused by simultaneous internal damping of viscoelastic material of beams that model the system and constructional damping which is derived from the rotary viscous damper in the support and from the translational dampers in slides of telescopic boom. In this work, damped vibration frequencies and the degree of vibration amplitude decay for selected values of the damping coefficients and variable geometry of the system were calculated.
