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.
Key words: Axis-disc structures Dynamic characteristics Random
variables Reliability constraint Optimization design
