“…Topology optimization of suspension component is performed by Lau [5] based on the modal tracking method of vibration mode weighting coefficient. Zhu Denglin [6][7] is based on dynamic compliance for the topology optimization design. Static and free vibration characteristics of micro hard disk drive suspension is treated by Wu Han [8] as optimization objective to study the topology optimization problem of the hard disk drive arm.…”

in order to guarantee the reliability of the hard disk drive data read/write and slider positioning accuracy, the suspension first order bending frequency, first order torsional frequency, first order sway frequency single objective topology optimization model which were based on solid isotropic elastic material penalty (SIMP) method were put forward, and the suspension multi-objective topology optimization model was defined by using the weighted method. Through the topology optimization design the hard disk drive suspension new topological structure was obtained. The results show that hard disk drive suspension single objective and multi-objective topology optimization design objective frequency are large promote than that of the initial design.

A numerical method for structural dynamic topology optimization and sensitivity analysis is presented by using RKPM. In this paper, the relative density of node and maximum fundamental eigenfrequency is respectively chosen as design variable and the objective function, and then the mathematical model for dynamic topology optimization based on RKPM is built. During the process of modeling, some effective measures are taken to dispose the multi-eigenvalues and localized modes. Subsequently, the sensitivity analysis equation is proposed by using Direct Differentiation Method. Finally, by integrating the above sensitivity analysis with Optimality Criteria method, the dynamic topology optimization of an example is performed successfully. Numerical example shows that both checkboards and localized eigenmodes do not occur during topology optimization, and it indicates the proposed method is valid.

“…One classical example is the controlled miniaturized swing arm type actuator installed in optical disk drives for mobile electrical devices. They require highly efficient dynamic characteristics and the optimization of performance under size constraint (KIM; KIM; HAN, 1999;YU;LIU, 2003;WANG;JIANG, 2006;PARK et al, 2007;LEE, 2007;SUN et al, 2009;SONG;KIM, 2012). The suspension assembly in the head disk interface must provide high reliability as a slider following capability for disk run-out, and it must also allow for good servo control during track seeking, settling and following (YU;LIU, 2003).…”
