Using Optistruct solver, lightweight design for beam structure of a large rotating device has been carried out, due to its overweight of mass and structure material exists redundancy situation. The optimization structure of beam is obtained under the constraint condition which ensuring the structure to meet stress, displacement deformation and miss minimization etc. The analysis results show that after the optimization, the mechanic performances of beam structure satisfy design index, and material distribution is more reasonable, and which achieved the goal of reducing weight of beam structure.
