Optimization of the Hinge Point Position of Luffing Mechanism in Reach Stacker for Container

Abstract

The luffing mechanism of reach stacker is the core of big arm lifting mechanism. The hinge point position in it influences directly the comprehensive performances. The mathematical model of three hinge points was established through the force analysis of luffing mechanism, which aims to reduce the maximum force of hydro-cylinder and decrease the oil pressure of hydraulic system. A hierarchical ordering method was utilized to optimize the multi-objective problem. The optimization calculation was presented by using the genetic algorithm in Matlab. Experimental results indicate that the optimization enhance the comprehensive performance of reach stacker. And this also provides important foundation to the parameters design of luffing mechanism.
