Abstract: The problem of dynamic optimization with the reliability constraint of the frequency for the random structures of axis-disc is studied. Considering the randomness of structure parameters (mass density and shear elastic module), the structural dynamic characteristics is analyzed based on probability. The structural optimization design model is developed with the reliability constraints of frequency or forbidden frequency domain, in which the structural dimensions are taken as design variables and the structure weight is taken as objective function. Finally, one example is given, and some conclusions are obtained.
