Optimization Design of Walking Beam Based on Stiffness Constraint

The excessive deformation of walking beam which is used in automatic packaging line of cathode copperplates is analysed. The mathematical model of optimization design of the walking beam is established, using deflection less than 7mm as a constraint condition. The optimization is completed by COSMOSWorks and the most optimal deflection is 6.95mm, the most optimal mass of the walking beam is decreased 25.2%. The optimization also indicates that strength of the walking beam is surplus and further optimization is feasible.
