Competitive algorithm is a heuristic optimization algorithm with parallel ability, its searching mechanism simulates the motive to the support- rate in the electing activity. In this paper, the competitive algorithm is applied for optimizing the structure design of machine tools spindle, and an example is processed to illustrate the utilization in the structure optimization design. Firstly a mathematic model of optimizing the structure design of machine tools spindle is achieved in terms of the condition of meeting all constraints to acquire demands of the best stiffness and the least material, then the optimization problem is solved by means of competitive algorithm and the design parameters of spindle structure are obtained. The result shows that competitive algorithm is practical and effectual in mechanical optimization design.
