基于多保真度代理模型的混凝土泵车臂架销轴轻量化设计
Lightweight Design of Concrete Pump Truck Boom Pins Based on Multi-fidelity Surrogate Model
摘要
Abstract
As a key connecting and supporting component in a concrete pump truck boom system,how to reduce the mass of the pin shafts was a noteworthy issue in boom design.A parameterized fi-nite element model of the hollow dumbbell pin shafts was constructed based on control parameters.Then,a more accurate feature mapping based MFS(FM-MFS)model was established through the mutual disturbance of high and low fidelity models and the reasonable allocation of high and low fideli-ty data.Genetic algorithm was used for optimization to obtain the optimal design scheme for the hol-low dumbbell pins based on this surrogate model,achieving a weight reduction of 36％.Through the-oretical,simulation,and experimental verification,it is shown that the hollow dumbbell pin shafts constructed based on the optimal parameters of the surrogate model may achieve lightweight and ma-terial consumption savings while still ensuring the physical and mechanical properties,which provides data support and reference for further applications in the future.关键词
