The Topology Optimization Methods on Quasi-static Structural

摘要

Quasi-static structure in each configuration and load conditions may be static stiffness or frequency of a special vibration mode can be optimized to meet the design requirements. Considering the size disparity in stiffness and load conditions, the unit strain energy density as the unit of sensitivity is proposed as the basis of cell properties to modify the sensitivity of the dimensionless mixing measure, and use the evolutionary algorithm with recovery function, calculation will be simple and implement easily in the large-scale finite element software, and can quickly reach optimal goals. Meanwhile, the proposed calculation eigenvalue sensitivity of unit and sensitivity synthesis method can also be taken into account static sensitivity and dynamic sensitivity to meet the dynamic performance requirements.
