Currently our design engineering team uses a fairly extensive and well established set of Ansys analysis routines. While these analysis methods are fairly well standardized, the actual model generation has not been standardized to date. Depending on the individual designers skills and preferences, there are a variety of methods being employed for getting the geometry into Ansys for analysis. The model generation may also be affected by which analysis the engineer intends to run. Through the use of process manager we are working to introduce a more standardized as well as streamlined approach to model generation. This will allow us to cut model generation and iteration time for experienced users as well as automatically building in features so that each initial model contains everything needed to be used with our standard analysis routines. It will also have an added benefit of cutting training time for newer users, as well as broadening the amount of users that can create a useful FEA model for design engineering.

    • Introduction To Seagate
    • Seagate: Storage Leader • Seagate is the world’s leading provider of storage devices. – Q2 FY2012*: 47 million drives shipped; revenue of $3.2 billion • Provides storage for enterprise, desktop, mobile computing, consumer electronics and retail markets – Builds hard disk, solid state hybrid and solid state drives – Broadest product offering in the industry – largest customer base • 53,700** employees worldwide • Recently Demonstrated 1TB per square Inch!! – Potential to enable 60 TB drives ® * For second fiscal quarter ended December 30, 2011 ** Includes interns, contractors, and agency tempsMomentus XT - State Hybrid Drive

    • HDD Suspension Introduction
    • Suspension Component Cantilever spring component at the end of the actuator • Connects the rigid actuator to the recording head • Must hold the head very close and very precisely over the media (disk) – Very Close!!
    • Suspension Assembly • Laminated Circuit Component • Thin, formed sheet metal component • Stamped “base” component for mounting • Damper applied via adhesive • Small Piezo-electric components applied via epoxy
    • Finite Element Model
    • Model ComplexitiesMain Concerns For Model Generation • Complex geometry of laminated circuit – Currently use coincident mesh through all layers • Attachment of multiple components – Mesh needs to match up between components for defining attach points (welds) • Component partitions used for auto detect/selection in downstream analysis routines
    • Current FEM Generation Approaches Multiple approaches depending on component, desired analysis, and individual designer • Midsurface of 3D Cad for iges import • Ideas • Extruding in Ansys using 2D AutoCAD import • Hypermesh Non Standardized Models!
    • Process Manager Solution
    • VisionGoal is to provide an improved FEM generation tool that will be the preferred method of engineers • Fast – Cut model generation time for existing users – Cut new hire training time • Easy To Use – User “buy-in” » Need to be easier than current methods – Broaden user base » Techs could provide FE model to design engineer • Standardized – Incorporate all existing best practices – Prep model with proper features for downstream analysis routines – All models created with the same method, and contain same features, material props, etc.

    • Summary: So How Did We Do • Fast? – Generation time should be cut significantly • Easy To Use? – Step by step guided creation – Little to no Hypermesh experience required • Standardized? – Dependent on user “Buy-In”
