Transmission Oil Pump

09/01/2018 12:58 PM

Good Evening all,

I am looking for some project advice, I will be starting my Master Degree in Engineering next week and have chosen a project idea.

The project idea consists of designing an oil pump for a motorsport transmission but, with no information out there and manufactures not wanting to give away any trade secrets I am slightly stuck on how to pursue this idea

Starting with a 3D cad model and running the oil pump in MAT LAB, would be my first call although, thermodynamics will play a large roll I am wondering if there are specific oil pump design procedures?

Any help would be greatly appreciated!

Interesting....I would say the first thing is to lay out the basics, mechanical or electric, I would make a list of characteristics that are related and fill in the blanks....

List of specifications....

mechanical/electric

GPM... probably 1-2 GPM

operating temperature range....controls/sensors

cooling coil design/location/cfm/btu's

displacement/stroke/rpm/variable

adapter brackets and mounting locations/materials specification/weight/design life

Filters/maintenance schedule/materials and characteristics

heat load characteristics and performance curve/ temperature/humidity/atmospheric pressure

So you have to determine how much heat is being produced at max load, and the coil size and fluid flow and air flow needed to remove the heat at max operating temperature...also building something that will do the job, but doesn't fit, is always a struggle....I would start with several of the most popular brands, and research to find the failure causes, the weak spots, then try to improve the design....If the're bullet proof, then reducing cost/weight is always an approach you can take....

Check out motorsport.com. They have a writer there who is a former Ferrari F1 engineer who posts on all things F1 car technical. His name is Giorgio Piola. Reach out to him; from his posting style he may be the source your looking for.
