Only cheaper because I have a tame CNC operator at work and we're not massively busy in the factory at the moment 1 1 Quote Link to comment Share on other sites More sharing options...

monkeyseemonkeydo Posted Monday at 08:07 PM Report Share Posted Monday at 08:07 PM 2 year bump! Been meaning to do this for ages but could never think of a good way to do it. Anyway, 50% scale motorbike model (spine for now) to start working on crazy aero bits that are popping up in MotoGP. Design done in Solidworks. Most of the spine is waterjet cut with telescoping, IGUS bushed, forks and 3D printed wheels (done in two halves each) on our Creality CR-M4 large format printer. The bit at the top is a 6-component balance and beneath that is a little roll system to allow the model to be cranked over to +/- 60 degrees, in 5 degree increments, for cornering cases. 2 Quote Link to comment Share on other sites More sharing options...
forteh Posted Monday at 10:00 PM Report Share Posted Monday at 10:00 PM Does the steering angle not need to be taken into account? Quote Link to comment Share on other sites More sharing options...

In theory maybe but in practice I don't think it's critical and can be introduced later if necessary. At racing speeds I think the actual steering angles they achieve are quite small and for what we're looking at the lean angle is the critical thing. There's going to be a steep learning curve to work out what the hell the forces actually mean though as everything's on the piss relative to everything else and there needs to be a fair amount of translation and taring off offsets etc. 1 Quote Link to comment Share on other sites More sharing options...

Already thinking that we may need to model a rider hanging his leg out under braking... going to be an interesting project! 1 Quote Link to comment Share on other sites More sharing options...

Steel frame maquette with a stuffed textile covering, allow you to play with different body positions? Screws up your spine design though, perhaps you could have a rolling chassis mounted forwards of the spine on a spar to give uninterrupted airflow over the bodywork/rider? edit: you could 3D print the rider in limb sections and then incorporate that into the maquette Edited Wednesday at 10:43 AM by forteh 1 Quote Link to comment Share on other sites More sharing options...
