Optimum Design Study of a Hydraulic Pressure Derrick Based on Stability
The bearing load is very large when the hydraulic pressure derrick suspends cargo. The hydraulic pressure derrick is a very important component which transfers cargo load to hull. The method of optimization theory based on dual method was transplanted to optimize the hydraulic pressure derrick structure and the optimizing model of the hydraulic pressure derrick was established. The hydraulic pressure derrick structure was optimized under four load cases. The numerical results show that the structure strength and stability of hydraulic pressure derrick are fit.
