  • 1. By Jinmiao Huang Sidhant Sharma Anagha Pradhan Date: 11/17/2010
  • 2. Agenda  Introduction  A word about Autodesk  Intro to Autodesk Inventor  Intro to Mechanism Simulation  Mechanism Simulations  Live demo-1 : Slider Crank  Live demo-2: Reciprocating Saw  Comparison with SolidWorks  Features Comparison  Current User Growth  Market Share  Applications  References
  • 3. Introduction  A word about Autodesk  Intro to Autodesk Inventor  Intro to Mechanism Simulation
  • 4. A Word About Autodesk, Inc  An American multinational corporation  Focuses on 2D and 3D CAD/CAE packages  Founded in 1982 by John Walker Product Year of development Developed by Applications AutoCAD 1982 Autodesk, Inc Architecture, Engineering and Construction Maya 1998 Alias/Wavefront Media and Entertainment Division Softimage 2000 Softimage Media and Entertainment Division 3ds MAX 2009 Autodesk, Inc Media and Entertainment Division Autodesk Inventor 1999 Autodesk, Inc Manufacturing and Engineering
  • 5. Intro to Autodesk Inventor  3D mechanical solid modeling design software  Developed by Autodesk, Inc. in 1999  Working Environments  Part Modeling  Assembly Design  Sheet Metal Design  Frame Generator (structural members, joints)  Tube and Pipe  Cable and Harness  Dynamic Simulation  Stress Analysis (ANSYS)
  • 6. Capabilities Compatibility with other CAE Softwares Parametric Optimization Simulation FEA Mechanisms Thermal Fluid Flow Electrical Routing 3D Modeling and Assembly Tool and Mold Design What can we do in Autodesk Inventor 2011?
  • 7. Intro to Mechanism Simulation  Input driving loads, friction characteristics, and dynamic components  Run dynamic simulation tests to see how a product will work under real-world conditions  Optimize strength and weight, identify high-stress areas, identify and reducing unwanted vibrations, and size motors and actuators to reduce energy consumption  Inventor Features:  Condition definitions (materials, load, etc)  Point trace (path)  Graphing  Animated visualization/videos  Custom report generation
  • 8. Mechanism Simulations  Live demo-1 : Slider Crank  Live demo-2: Reciprocating Saw
  • 9. Steps for Mechanism Simulation 1. Open the assembly file 2. Check all the mates and constraints 3. Switch to Dynamic simulation environment from Applications Tab(2009) or Environment(2011) 4. Calculate Standard joints (automatic) and Insert remaining joint types (example: for gear meshing) 5. Apply motion, force conditions, etc 6. Generate plots using Output Grapher
  • 10. Live Demo1: ‘the’ Slider Crank Mechanism http://www.youtube.com/watch?v=LhJCi1RUyPk
  • 11. Results Comparison Time(sec) Autodesk Inventor SolidWorks MATLAB As seen in the three figures, the solutions given by Inventor, SolidWorks, and MATLAB are very agreeable. X-Position of the Piston
  • 12. Results contd… Autodesk Inventor SolidWorks MATLAB As seen in the three figures, the solutions given by Inventor is slightly greater than the analytical solution. Solidworks is more accurate. X-Velocity of the Piston
  • 13. Results contd… Autodesk Inventor SolidWorks MATLAB As seen in the three figures, the solutions given by Inventor is slightly greater than that given by SolidWorks and MATLAB Solidworks is more accurate. X-Acceleration of the Piston
  • 14. Live Demo2: Reciprocating Saw http://www.youtube.com/watch?v=V4mE4mR_2nY
  • 15. Comparison with SolidWorks  Features Comparison  Current User Growth  Market Share
  • 16. Features Comparison  Solidworks is more intuitive as compared to Inventor  Modeling is easier in Solidworks  Inventor has a great weakness in applying mates as direction has to be specified as positive or negative  SolidWorks gives the direction toggle option for mating thus easing assembly  SolidWorks can automatically detect joint types, whereas you have to specify them in Inventor  Better animations can be created in Inventor
