A Smooth Bidirectional Evolutionary Structural Optimization of Vibrational Structures for Natural Frequency and Dynamic Compliance

A smooth bidirectional evolutionary structural optimization (SBESO), as a version of SESO is proposed to solve the topological vibrating continuum structures for natural frequencies and dynamic compliance under transient load. weighted function introduced regulate mass stiffness matrix an element, which has inefficient element gradually removed from design domain if it were undergoing damage. Aiming at maximizing frequency structure, formulation using SBESO technique. The effects various weight functions including constant, linear sine on are compared. With equivalent static load (ESL) method, structure formulated by Numerical examples show that compared with classic BESO method can efficiently suppress excessive deletion adjusting rate function. It also found technique obtain efficient configuration boundary demonstrate advantages over
