  • Vibration analysis of SL6 shiploader boom luffing winch platform
    2010 The 2nd International Conference on Computer and Automation Engineering (ICCAE), 2010
    Co-Authors: Lian-dong Zhang, Deying Zhao, Rong Shi, Cai Liu
    Abstract:

    Boom luffing winch platform is located in empennage of SL6 shiploader at HUANGHUA PORT. The platform vibrated violently when the boom luffing lift and descend in high speeds during industrial process, which severely restricted the equipments productivity. To found out the vibration source of the platform, the boom luffing winch system dynamic model was been built, the influence of winch exposed gear meshing frequency to winch torques was been investigated. The results indicated that the response torque of winch Pinion Shaft enlarged with the raising of motor speed and the maximum response frequency left drifted, gradually closed to the exciting frequency. To research the influence of boom luffing winch system dynamic response to the vibration of the platform, ANSYS software is used to complete harmonic response analysis for boom luffing winch platform. The results indicate that the location of winch in the middle of the platform occurred vertical vibration under the 17.76 Hz exciting frequency which approached closely the high speed meshing frequency of winch exposed gears.

  • TORSIONAL CHARACTERISTIC OF SL SHIPLOADER BOOM LUFFING WINCH SYSTEM
    Journal of Mechanical Strength, 2010
    Co-Authors: Zhang Lian
    Abstract:

    For the SL shiploader boom luffing winch system platform vibration,using lumped mass method,the boom luffing winch system Shafting torsional vibration model has been built,which considers the nonlinear integrated gear mesh stiffness of the winch gears and winch nonlinear loads when boom luffing swinging at different speeds.Using variable-step Runge-Kutta method the dynamics responses of the torsional vibration system have been solved respectively during typical motor speeds low 235.5 r/min,medium 674.5 r/min,high 958.8 r/min,then the dynamic torques responses of exposed Pinion Shaft have been calculated,and through spectrum analysis the spectral response characteristics of system has been obtained.The calculation results show that as the motor speed rising,the influence of the integrated gear mesh stiffness to torsional vibration system has been enhanced,and the torque response peak close in mesh frequency.The calculation results accord with experimental results on frequency characteristics,and verify the boom luffing winch system torsional vibration model is correct.

  • Analysis of Threaded Connections for Differential Gear Pinions
    Volume 2: Advanced Manufacturing, 2016
    Co-Authors: Dario Croccolo, Massimiliano De Agostinis, Stefano Fini, Giorgio Olmi
    Abstract:

    The present paper deals with the failure analysis of a Pinion Shaft belonging to a differential gear for offroad machinery applications, namely wheel loaders. The motivations of the study arise from some in-field failures, which resulted in the fracture of the Pinion Shaft, originated at an external groove located at the end of its threaded portion. The issue has been tackled by means of analytical, numerical and experimental tools. The observed failures have been demonstrated to be due to the in-service loosening of a ring nut, whose function is to preload the tapered rolling bearings, which support the Shaft.Copyright © 2016 by ASME
