Abstract:The existing electromagnetic hanging beam is independent of each other, sucker is directly connected with the hanging beam body rigidity, and the stresses in this type of hanging beams are veryuneven and easy to wear. The authors designed a kind of electromagnetic hanging beam with six hanging points based on flexible technology. According to the flexible link system structure, optimized model is established and the constrains are set by using MATLAB with multidimensional constrained optimization function fmincon to optimize the dimensions of the follower rocker cam (the left rocker arm 7) and link 3, and achieve the automatic adjustment of electromagnetic disc height. The proposed design could meet the requirements of electromagnetic hanging beam, and it provides the necessary scientific basis for the multi suspension balance hoisting of the electromagnetic hanging beam flexiblelink system.
