HDD Suspension Topological Optimization for Dynamical Characteristics

With the development of higher data density and the faster data streaming, a HDD(Hard disk drive) is required to move faster with greater positioning accuracy. In this stringent situation, even small mechanical vibration may result in error in data reading. Present work is focused on the methodological research of topology design about HDD suspension based on dynamical compliance. As a result of these researches, several new topological structures of HDD suspension are obtained, which are large different from previous work.. It is discovered that the topological structures based on dynamical compliance are similar to that based on static compliance, first order torsion and sway frequencies at some local areas.
