Ready for a new challenge? This week we introduce trailer manufacturer Tikitreiler. They need your help to redesign their torsion axle and are interested in just what you’re able to dish out.
Design a clever solution and win $1,500 USD! Tikitreiler wants to see your solution for an axle. An Axle which contains a parabolic springs and a clever solution for integrating the spring with the axle. We have all the requirements, files and other guidelines listed below. A new axle design. $1,500. Are you up for it?
The current design
- The trailer doesn’t withstand a load well (50x50mm steel profiles are currently used between hubs)
- The spring and axle assembly is time consuming to manufacture (welding the threaded rods to the square profiles takes too much time)
- The Axle / spring / shock assembly contains too many parts
Files to be used in the new design:
Hub, shock, Spring – All CAD files found in GrabCAD library and in the compressed zip file under Specification link .
Axle solution for two pair of wheels
The whole system (2 axles) must withstand a load of 1850 kg (4075 lbs) with a safety factor of 2 (meaning 3700 kg or 8150 lbs)
The given parabolic spring must be used on both axles (4 springs all together)
The given shock must be connected to the axles/springs (4 shocks all together)
The given hub must be used (4 hubs all together)
The Dimensional references shown on the drawings must be met
The solution must be as easy to produce and manufacture as possible. The production volumes are high so saving material and assembly time is very important
The Function has top priority over looks of the design
The system has to have two separate identical axles
Distance between the 2 axles has to remain between 650-700 mm
The best solution will earn $1,500 USD
The winning design will be chosen based on the requirements on the right
This competition is open to everyone
You can participate with as many models as you like
Team entries are welcome. With a team win, the prize money will be transferred to the team leader who is solely responsible for splitting it among team members
Only models uploaded to the GrabCAD library will qualify for the competition
Tag your model when uploading with “Tikitreiler” to index your model for the search
You can upload a private model, but you need to share access to email@example.com
Privately uploaded models will be made public after the deadline
Models can be done in any CAD software as long as STEP or IGS files are provided as well
Competition starts on August 16th, 2011
Competition ends on August 31st, 2011
The winner will be selected by a joint jury of Tikitreiler and GrabCAD and announced on the GrabCAD blog
