| 摘 要： | 大型起吊船在起吊货物时负荷很大,液压扒杆结构是将起吊货物载荷传递到船体结构的最重要构件之一.本文以二次规划的准解析法优化理论为手段,在考虑风载、横纵倾、惯性载荷作用下优化了液压扒杆结构,使优化后的结构满足强度与稳定性要求.

| Abstract: | 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. |
