Weight Reduction Design Methods of Wring Based on Load Spectrum

Abstract:

The hydraulic systemic load spectrum of wring has been constructed by time with press and flow rate under deferent working condition on ship. The root mean square value of reel axial torque was calculated by weighted processing and was taken for the basis of the calculation on structure critical load. Based on the block of load spectrum, the virtual fatigue calculation showed the relation about the static strength and critical load block of load spectrum. Keeping the ratio of the static strength and critical load, the force analysis of wring reel aimed to the structure weight reduction by finite element analysis (FEA). The established wholly parametric and weight reduction model of wring structural part had been computed and meets the strength and stiffness requirement. The weight of this reel is reduced by 15.5 kg and lightweight effect is 8%. This method of weight reduction can be used to the reference on the design of hydraulic deck machinery of ship and hydraulic actuation construction machinery.
