  • 5. Romax solution - CONCEPT Slide 5 CONFIDENTIAL © Copyright 2013
  • 6. CONCEPT – Features and benefits • Allows the user to do everything required to create a finalised concept design of a gearbox or driveline, before further refinement in RxD / CAD Full Gearbox & Driveline Modelling Bearing Load Calculation Gear Ratio Optimisation Modelling Templates Intelligent Modelling Bearing Database and Selection Bearings Gear Design, Manufacture and Rating Gears Vehicle Performance Simulation Speed, torque and loads Cost modelling Efficiency predictions Slide 6 Vehicle Packaging checks System analysis CONFIDENTIAL © Copyright 2013
  • 7. CONCEPT – Features and benefits Full gearbox and driveline modelling • Everything to model a complete driveline: o Gears, shafts, bearings o Engines / motors o Wheels o CVT o Chain / belt o Synchros Slide 7 CONFIDENTIAL © Copyright 2013
  • 8. CONCEPT – Features and benefits Full gearbox and driveline modelling • Any gearbox or driveline layout can be created in minutes Slide 8 CONFIDENTIAL © Copyright 2013
  • 9. Demo • Play videos: o Building an 8 speed AT - fast.mp4 (4 mins) • Talk through building up a very complex A/T model o 8 speed AT with front axle.mp4 (2 mins) • Explain how you can model the entire driveline, including engine / wheels etc. o Prediction of gear and bearing forces.mp4 (1 min) • Explain how from these rapidly created models, you can calculate gear and bearing forces, enables you to start your housing design, bearing selection etc.) Slide 9 CONFIDENTIAL © Copyright 2013
  • 10. CONCEPT – Features and benefits Gear ratio optimisation • Description: o Automated ratio selection for complex power flows • Inputs: o Gearbox layout o Required gearbox ratios • Outputs: o Individual gear ratios to achieve the desired gearbox ratios, for further investigation • Benefit: o Automated process for creating suitable gear ratios, especially useful for complex planetary arrangements o Increased modelling speed Slide 10 CONFIDENTIAL © Copyright 2013
  • 11. CONCEPT – Features and benefits Gear design and rating • Development: o An easy to use gear design and analysis process • Benefits: o Gear design process integrated into the rest of the driveline design process in a common platform o No issues with transferring data between software tools Slide 11 CONFIDENTIAL © Copyright 2013
  • 12. CONCEPT – Features and benefits Bearing selection • Bearing catalogues to enable bearing selection based on calculated dynamic capacity • Benefits: o Enables bearing selection very early in design process o Gives housing loads – required for housing design Slide 12 CONFIDENTIAL © Copyright 2013
  • 13. CONCEPT – Features and benefits Efficiency • Predicts gear and bearing losses according to ISO 14179-1/2, considering component design, operating conditions and lubricant • Alternatively, use user defined component loss curves for gears, as a function of speed and/or torque • Benefits o Enables efficiency to be considered at the earliest stage in the design process Slide 13 CONFIDENTIAL © Copyright 2013
  • 14. CONCEPT – Features and benefits Cost calculations • Component and assembly costs can be calculated • Based on either o Material cost per kg o User defined cost • Alternatively, the user export dimension and material parameters as a csv file for own calculations • Benefits o Enable cost to be considered at the earliest stage in the design process Slide 14 CONFIDENTIAL © Copyright 2013
  • 15. Product Overview - CONCEPT Rapid gearbox concept design and analysis • Features: o Driveline modelling with gear ratio optimisation o Investigate multiple complex gearbox and driveline layout concept designs with rapid, easy modelling o Initial gear, bearing, synchro and clutch sizing, design and selection o Perform noise, durability, cost and efficiency assessments at early stage in design • Benefits: o Improved quality and reliability of manufactured product due to early analysis o Seamless workflow from planning to detailed design, linking groups within an organisation reducing errors and improving processes o Faster to market with reduced development costs Slide 15 CONFIDENTIAL © Copyright 2013
  • 16. Feedback so far… (Beta Release - Major OEM’s and Tier 1’s) I just did these calculations without Concept, it took me several weeks. In Concept, it would have taken me a few hours, and I could have iterated in a couple of days. We’re really excited about what Concept can do. I want our Designers to be using this ! Seems to be good agreement between Concept and our existing tools Slide 16 Well done – great customer focus This seems much better than our existing gear design solution CONFIDENTIAL © Copyright 2013
