University design project

[haroman666]

Hi all.

This isn't going to be a long interesting project where you'll see developments as I go along. It's more of a "Yay i'm proud of what I made" quick picture whoring.

It's just some screenshots of my CAD modeled assembly of an "Electric Motorcycle Powertrain".

I used CATIA V5 and i've spent a large number of hours creating something that I am happy with.

I appreciate it's not a majorly complex design, in terms of; I haven't gone out of my way to think of unique engineering solutions for some of the problems posed during the design process.

Points will be given to those who can spot which motorbikes I have taken/stolen inspiration/ideas from

I await the critique of BCF

Shit, electric bikes fly?!!one!

Pretty cool though, I struggle making a CAD screw, let alone things like this

NSR 500 back end, and you deserve real kudos for that CAD work man, great job!

[hmmmnz]

is this thing actually going to be made??
if so id ditch the sss and use a regular swing arm,
and use a chain not a belt,
looks good though

Thanks for the compliments

NSR500 is a bit off the money there Louis... Definitely some Honda in there though.

And Hmmmnz: Nah not going to be made unfortunately. It's just a design project. So I'm just covering the process pre-production.
However I may see if I can get a company to rapid-prototype it just so I have a wee little model of it!
And as for SSS; I wanted something that was aesthetically pleasing to myself. My favourite bike uses a single-sider and so major inspiration came from that bike. I'm aware that it would be a better design if I'd gone for a normal swingarm.
And the choice of a belt was based on various points but the main one being: It's a clutchless, cush-driveless drivetrain and therefore is not going to be very smooth to use: A belt is smoother than a chain so reduces ride harshness when pulling away and rolling off the throttle. I have a whole page dedicated to drive-type choice.

Slingshot style frame and an NC35 rear end, did you consider what the rest of the architecture would look like? IC engined bikes have to leave a massive hole for the engine, whereas you have a bit more freedom with where the batteries can go.

electric machines in automotive applications pretty much always have to go through a gearbox btw.

[haroman666]

Electric machines have a varying spread of torque just like an ICE

https://www.motoredbikes.com/attachment.php?attachmentid=22151&d=1256999307

as you can see the curve is flat at the lower limit. As power is torque x revs it would mean that would limit your power right where you want to pull off from 0 revs. Maybe not such a problem on a 200kg bike as on 2t of car though.

[Redoko]

If you'd like, when you've finished I could put a few minutes aside to visualise it for you.

You got weeny spring syndrome dude.

Seriously, that's a faggot spring.

But when pulling away, is it not Torque that's required... Turning force. High torque is a high turning force which is required to get the bike moving (0 - Low rpm).
Power is needed to sustain high speeds: high rpm, less turning force needed.

Oh jeez that's awesome!

Kinda puts mine to shame really

What package did you use? What was your course?

I used Solidworks for that, though I now use Catia, they're very similar. I did mechanical engineering with CAD (although I don't know why the course was called that, we only did 2 CAD modules)

[haroman666]

Ahh cool. I heard that Solidworks is easier to get to grips with, is that true?

Cause i'm mostly proficient at Catia solid part modelling/assemblies and a bit of surfacing. But if Solidworks is easier then i'd like to learn it too.

Wow... Only 2 modules? Does seem a bit odd putting it in the course title. I'm doing Motorsport Technology and i've had at least 1 module that involved Catia or CFD every semester (6 semesters over 3 years)

Jesus. Is this what constitutes reality? Pass me a fucken' revolver.

when that shock were to compress would you get some crazy head angle on those forks.

[Hetzer]

I must have had some idea what I meant last night, but this morning I have not a clue. My apologies, I sounded like a twat.
