2. Slide 2 Dr Hans Prem Dr Luan Mai Mechanical System Dynamics Pty Ltd (MSD) Melbourne, Australia

3. Slide 3 Context NTC funded project; Aimed at increasing PBS take-up; Deliver safe, high-capacity/productivity vehicles; Focus is 20m 6-axle prime mover and semi-trailer; Blueprint design approach; Design flexibility with broad application; Available to everyone at low (no?) cost.

4. Slide 4 2010 Survey of Motor Vehicle Use (Australian Bureau of Statistics) Number of Vehicles

5. Slide 5 2010 Survey of Motor Vehicle Use (Australian Bureau of Statistics) Total Kilometres Travelled

6. Slide 6 2010 Survey of Motor Vehicle Use (Australian Bureau of Statistics) Total Tonne-Kilometres Travelled

7. Slide 7 Design Goals (6-axle prime mover and semi-trailer) PBS Level 1 Performance/Access; Up to 20m overall length; GML, CML and HML loading and 6.5t on steer; Maximum load space; Based on available equipment; Modularity and interchangeability.

8. Slide 8 Process Stakeholder consultation; Parameters set to meet industry needs; Define Blueprint envelope; Develop generalised Blueprint design approach; Prepare Formal PBS application.

9. Slide 9 Outcomes Formal PBS approval; Generalised approach to Blueprint design; Each design is stand alone; One or more designs easy to produce and approve; Support tool (beta version, final testing).

10. Slide 10 The formal PBS application that underpins this project is complex…

12. Slide 12 Front Overhang Detail for Dimension Set #2 of 3

13. Slide 13 Support Tool (Excel Spreadsheet Based) Dimensions; Tyres; Powertrain; Loads, CGs and Suspensions; Drawings produced; Submit entire spreadsheet as application.

14. Slide 14 Dimensions (worksheet)

15. Slide 15 Dimensions (worksheet)

16. Slide 16 Tyres (worksheet) Data can be supplied by tyre manufacturers; Or, each tyre manufacturer to supply a list of tyres that meet this specification.

17. Slide 17 Powertrain (worksheet) Data can be supplied by manufacturers; Or, each manufacturer to supply a list of engine, gearbox, final drive ratios that meet this specification.

18. Slide 18 Loads, CGs and Suspensions (worksheet) Data can be supplied by manufacturers; Or, applicant can work with manufacturers.

19. Slide 19 Drawing Spreadsheet based CG height estimator – in preparation

20. Slide 20 Summary PBS approval for this Blueprint is in place; Working version (beta) of Support Tool available; Generalised approach to Blueprint design in place; Scope to produce many approved designs quickly; Modularity and interchangeability can be tested; Migration of popular designs into law a possibility.
