Bus 3D model project, help request

[Dummiesman]

Good news! A lot of the issues with the physics going weird were the result of me being an idiot, and looking in the wrong places for the issues.

I have people testing a release candidate now, and if all goes well, it should be ready by the end of this week!

Aside from that, there are a couple last things I want to touch up on. One of which is again the doors.

They work fairly well, and high speeds + open doors means they get forced closed after a bit. But because of them being made that way, they have some play to them while closed. I'm going to go ahead and guess that, if you make a sudden turn at ~40mph, the doors aren't supposed to move a bit?

I'm gonna say once I got my electric doors adjusted correctly that they don't move during turns at 40mph or even 50mph -- that said, I probably wasn't making real sudden turns at those speeds... How many lateral G's would you like the bus to pull?

[Dummiesman]

My doors end up moving a bit at ~0.6 g's

EDIT: Oh, do you know what the top speed in reverse is? :P I've got around 12mph

There's a fun opportunity!
Variables -- fer instance the ol' chysler 727 3sp automatic unlike most automatics could go into 2nd and 3rd gear ratios while in reverse...
Being a typical teenage delinquent I used to delight in getting my dads ol' station wagon into second gear backwards -- remarkable that I didn't flip it really...

Back to the bus...
I'm not sure how many different reverse gear ratios the Allison 2000 came in.
Seems to be a few, I'll go with the -4.49:1 used in the lighter duty versions
Then the rear diff ratio used. Mines 5.13:1
Assuming a 42" (11Rx22.5) tire...
Then you find a gear / speed / rpm calculator and plug and play...
https://spicerparts.com/calculators/...rpm-calculator
That gives me 13mph at 2400rpm
and 14mph at 2600!

Bored enough to do the math but not bored enough to go out and wreck my bus...
(I highly doubt I've gotten over 5mph in reverse yet...)

[Dummiesman]

Oh yeah, that can be solved with this crazy thing called math!

So I guess what I have is about accurate
BTW. Someone made a mod to adapt a standard trailer hitch into a fifth wheel and well. I attached a tanker trailer to the bus and man, this CAT has some torque to it!

The standard tow hitch was bending all over the place though

[Jolly Roger bus 223]

your tow hitch was not standard?
attach a tow hitch to the frame rail with an adjustable height bar for the trailer attached?
now add high tinsel steel to that for a tow bar?

[Jolly Roger bus 223]

besides?
if that tanker trailer was loaded and running highway speed then the bus brakes wouldnt handle it?
so why not make a more realistic model of a bus towing something more realistic to the bus towing world?
my kids think games are fun.
i think real life? cause thats what i deal with?
i am hands on when things go wrong not computer modeling? if you want it correct in your video game then i want to see rolling down a hill.
my wife always said i went overkill so i would like to show her what subpar looks like?

Don't know what this is supposed to imply.

Anyways, the attachments are entirely up to the player. BeamNG has a variety of inbuilt trailers, and the tow hitch -> fifth wheel adapter is a mod.

I'm just having fun with the things that are possible

[Dummiesman]

I've just released the mod for people to use!

Hopefully it's good
or maybe nearly 2 years of work will be 'just alright'. Who knows,

@banman, Native, others who chipped in
Thanks a ton, this thing wouldn't be half as good as it is now without all your help.

One super big CONGRATULATIONS!!!!

Wait a minute, two years andyou have not even stared on your buildout???


Sounds about right.

Heh
The base is laid out now at least. The difference with me is I first had to build the bus itself. A step most usually skip

Except for Musigenesis!

You're very welcome!

I couldn't help myself, I made a shortie!



It's like the school bus equivalent of one of those tiny camper trailers

[Native]

So nice! Now a lift kit with 4x4 to boot!

[Dummiesman]

I think I've decided on it. When I start "building" (modeling ) the converted one, it'll be in the short, high headroom body. Less space to fill, easier to design that way, and I've just taken a liking to the green painted one I have here. I'm actually quite excited to get started on that

Oh wow .... I think your buildout will be a GREAT boost for this community. You *NEED* to do this, and start its own thread.


Also, (in a separate thread) it would be so cool for you to do a roof raise on this model so we can toss both off of the same hill and put to rest the question of "is a roof raise strong enough" ... so WE ALL do not have to toss our buses off that hill.



When you do start a thread, pease post a link to it here so we all know to follow.

[Dummiesman]

Man, roof raises scare me

I worry about the filled in parts being fragile in a rollover situation. Maybe I've just seen some dodgy roof raises though

Now is you chance to overcome your fear ... you can show what happens.


I am assuming you can model the welding/construction techniques.
