Flight simulator help.

Hi!
I just starting to building a motion simulator. I think 3DOF i the best setup for my sim.
So I have some questions.
1: I have Line actours with 300mm stroke.
2: I also have Hydrualic pistons and PWM valves.
3: I also have 250W 24V DC motors with pulse encoders.
4: I can fix NC drives and motor for that.
So the question is WISH is the best and esiest way to built?

Question 2
Wish interface should i use for control 3 axis?
I have looked at tronics interface ,but can it handle some of my options?

I will be happy for some answers.

Best regard Micke

Hi Micke!

Welcome

Do you have a sketch of the motion sim you are planning? This would be very helpful,
then we can see what exactly you would like to build.

Tobi

Thanks,
I was thinking some of this models.

Hi Micke,

My AVR motion controller interface supports 2DOF motion cockpits for now. But I will program a 3DOF and a 6DOF support soon. Just have to finish with some other minor issues first on the motor control side.

The simulator examples you showed us are a bit expensive to construct. Unless money doesn't stand as obstacle to you... ;-)

Thanks for the quick answer.

I get those NC servos with NC motors next week



Any good ides of platform designs?

Hey, aren't these industrial servo controllers!!?? You propably need to put lots of programming effort to make their inputs compatible with x-sim software...! I think that they have serial input, unless they use CAN!

Can you give us more details on the model or a relative link?

Hi!
Yes they are industial servos.
The only input for get it running is:
RF = enable servo reglerfrei
E1 = Analog input +10V to -10V -/+10V full speed forward/backward
E2 = analog signal ground

I think they can work with measurment converter IN 0-5 or 0-10 # OUT -10V to +10V

Or am I on wrong track?
Because I can get 8 motors and servos next week from my job.

Yes, if you can find 0 to 5v converter to -10 to +10v, you will be able to use them with my AVR motion controller!

Its easy to translate the PWM signal it outputs to voltage using an RC filter (resistor-capacitor). But there is a little conversion I have to do to the programming to allow positioning in such way, as now I drive h-bridges with 0 to 5v meaning the speed and I use another two digital lines to indicate the direction...!

So If you decide to try my AVR motion controller, I'd have to make a proper firmware just for your industrial servo controllers! Tell me when you are ready, to start preparing it... :wink:

Hi Micke,

Welcome!

There are a bunch of differnt simulator concepts, and they all have their pro's and con's. I wont and even couldnt tell you which concept is best, because it is an individual decission, that depends on many factors [in particular money, space (linving room, garage or hangar ), what should be simulated and your technical skill level].

I just can tell you, that 250W Motors arent enough for platforms. Even geared.
They should fit for pivoted concepts, but not for unsupported platforms.
Tell us how much torque (nm) the motors have.

In that particular case, that you have access to hydraulics with proportional valves, you should go this way if you asked me.
2,3 or 6dof depends on how many pistons, valves or motors you can afford or organise.

Do you have mechanical and/or electronical skills?

Christian

Thanks for your answer.
I have access to machine hall and a house.
I can´t tell you the moment right now ,it comes from a wheelchair. I find it out.
I have about 500+ PWM valves at my work.
And cylinders in many diffrent styles.
My work title is Maintenance engineering.
Mostly electric but a lot of mechanical also.
The work is to develop testing riggs for gearboxes and Sinumeric NC.

Hi Micke,

I forgot to ask you about the motors. If they are plain DC motors then you may not be able to drive then using those industrial NC servo driver! These suppose to handle brushless 3-phase servo motors... Correct me if I'm wrong...

With the normal DC motors you have its better to look after for a suitable 24v H-bridge motor driver... I'll give you some suggestions later (must have a look in my archive).

Regards, Thanos

Yes you have right those are brushless 3-phase servo motors.
Otherwise the small DC engine will be indiansmoke :bandit:
