| Abstract: | In order to use trolley carrying laser receiver for crane track detection, the trolley must have good stability. The influence from trolley must be reduced. The 3D model of crane′s track inspection trolley was established with Pro/Engineer. The modal analysis of its chassis was done by Pro/Mechanica. Its natural frequency and vibration mode was seek out for structure improvement. Then, the natural frequency has been significantly improved. Vibration effects have been reduced. This trolley provides a good platform for laser receiver. |
