  • In order to get the lightest weight of the blisk under the safety working condition,the three-dimensional (3-D) parametric model of the blisk and the mathematical model of the structure optimization design were built.Then the structure optimization design of blisk was completed based on ANSYS platform.In conjunction with the relevant design principles and methods,the disk's meridian plane was firstly optimized to meet the structural design strength criterion,and then the 3-D model of the blisk was built with the chamfer at blade root and 3-D optimization was perform on the design parameters for example,the thickness of the rim,the chamfer at blade root and the dish hub.The effect of each design variable on the Von Mises stress at the chamfer of blade root and at the dish hub was summarized.The whole optimization process only took about three to four hours.
