| Abstract: | With the derrick mechanism of bucket wheel stacker model DQ1000/ 1500.45 as objective, a finite element model of 3D beam is established and the set-up and solving procedure of system's kinematic equations are analyzed. System's natural frequency and corresponding mode of vibration are solved by way of sub-space iteration with the aid of SUPERSAP 91 software. |
