Our Managing Director, Greg Morehouse, got the opportunity to do another Guest Lecture 27 Sept 2017. He talked about some of Motovated’s key projects in a 2nd-year Design Course at ARA for Graeme Harris. Greg loves highlighting our key projects, and chose to talk about the Rail Bogies we designed for KiwiRail’s Transcenic and Transalpine Rail Carriages, as well as Forest System’s (SATCO’s) 528 Feller Delimber design and analysis.
The work for KiwiRail was intensive and robust. Initial design concepting and options analysis was followed by detailed design, detailed analysis including Solid and Shell Element Finite Element Analysis (FEA) for parent plate, fatigue and weld analysis. Fatigue test plans were developed and carried out on prototypes. Weld specifications and inspection test plans were developed and ongoing engineering support was provided for these bogies.
The proof of all that hard work is in the pudding, as they are amazingly smooth and quite running, see the Press article written by Roy Sinclair “World-class scenic transport” here. In it he says, “New rolling stock (carriages) for South Island scenic rail journeys are as good as, or better than anything I have experienced anywhere else. They rival equipment used on Switzerland’s premier scenic rail journeys, including the famed Zermatt to St Moritz Glacier Express. And, best of all, the new rail vehicles, classified AK, are New Zealand-designed and built.” and “An impressive feature is the quieter, smoother, ride provided by the newly- developed P13 bogie wheel units having a combination of primary synthetic elastomer axle springs supplemented by a secondary airbag suspension. The latter is in common use on heavy road vehicles. The P13 units were designed by Christchurch engineering firm Motovated Design & Analysis and constructed by Hillside Engineering. Motovated founder Greg Morehouse says the KiwiRail project was one of the most satisfying projects he has been involved in. He praises KiwiRail for resisting international pressure and keeping the AK carriage project in New Zealand.”

Once again it was great fun for Greg and the engineering students to interact, and for them to learn what it takes to excel at the forefront of engineering today.
