Akamai Project:Ā 3-D Modeling of the CFHT Declination Gearbox

ProjectĀ Site:Ā Canada-France-Hawaii Telescope

Mentor: Steven Bauman

Project Abstract:

The Canada-France-Hawaii Telescope (CFHT) has been in operation since 1979. Due to theĀ telescopeā€™s age, mechanical parts are beginning to show signs of wear and may soon fail.Ā This can result in poor observing and ultimately telescope downtime. Recently, increased telescope pointing errors indicated that original gears in the telescopeā€™s declination gearbox were showing symptoms of wear. The declination gearbox is responsible for the telescopeā€™s motionĀ about one of its two rotation axes. The primary purpose of this project is to generate a 3-DĀ computer-aided design (CAD) model of the entire gearbox. The new 3-D CAD model will replaceĀ the telescopeā€™s original hand-drawn 2-D mechanical plans, and the model will be verifiedĀ via functional animation of the gearboxā€™s moving parts in the CAD program. Using the newlyĀ created CAD models, manufacturers can then be contacted and custom replacement parts willĀ be ordered. The completed model can also be used to create a parts list for the gearbox, anĀ animated assembly/disassembly tutorial, and a stress analysis test to determine areas of possibleĀ failure in the future. Creation of this CAD model of the declination gearbox will facilitateĀ rapid mechanical repairs when needed, and help avert catastrophic telescope failure by allowingĀ for preemptive replacement of worn or damaged parts.
