assembly and handling

[aerox]

hi to all, finally after many hours and advice of freddygol I managed to shape what I needed!soever I tried to assemble everything, leaving no bond of freedom to the system and here we are.
Now I would like to make sure that the system can move if I move it with the mouse but something does not return to me, perhaps because I do not know how to use the multplo link.(or quaklche other option I did not understand)

I have a fixed piece to which another piece is connected that can rotate around a axis (through the action of a piston that is not designed for now.
on this piece that rotates is anchored a spherical snout (pallin to understand us), to the spherical joint collect a rod , then another rod is concentric to that of before (it would be a guide) and to the ecremite there is another connection by means of spherical snout. in the end the ball is connected to a hook which is bound on a fixed body. in practice the rotation of the raddle moves this kinematic chain and move in angular way the jaw.

doing all the links to the last step I can not take the connection between the two entities (ball on the raddle) and I assume that this does not happen because the system does not automatically allow a change of displacement/angle to the various bodies (made of gdl) so as to rest on a position that allows coupling

Any ideas?

Thank you

Hi, guys, I've been busy and I've been able to do what I wanted, but I still have a couple of doubts.

1)Is there a possibility to give displacement camps to constraints?(e.g. piston stroke, angle between two components)
2)think design can handle a spring that compresses?

thanks and hello to all

then I managed to do something that resembles the movement required, in practice in animation I used free movement by selecting initial and final pos of the components and the result is discreet, it would have been nice to assign precise variables between the couplings of the components but I did not understand how to do, I think you have to use the internal electronic sheet, however it gives me as settings of hole diameters and thread pitch. . .I don't see anything that looks like assemblies settings (e.g. offset between a coincidence).
on the web training there is something about animation but shows the first step (electronic sheet) and then says to look in the program guide...but I did not find useful info unfortunately.

hello and good morning to all, then, for the spring there is an optional application called think compensator, and it serves to do compressions and more (I don't know how to say much because I've never used it). good for the video, from what you write, it seems to me that you managed to pull out of the guide many things, you miss to assign to the quota of the positioning a name. I explain, once the positioning is done, e.g. the offset, from the history tree, click on the positioning, select shows odds. now go look for the interested quota, dx key, change quota, in the window that appears you will have two caselline, one with a number (equal to the assigned ophset), one empty. In that blank you put the name of your variable, which I know... a, x, c, run, length... and so on. once you have the quota with the "name" you can set the video with that quota (quota that you will also find in the electronic sheet). Hello everyone

I forgot, point 1....... Wellhh following the process I described above, you can assign variables to all the odds you want, then from the electronic sheet you can manage the values (a bean, you can also make small expressions):biggrin::biggrin:

Thanks was just what I was trying to do but I didn't know where to do it! Now I try now!

Hi.

hi, I tried on a test file and I can drive the share with the electronic sheet, only that I can no longer move to pleasure the object with the mouse cursor but if I want to move it or create an animation using the share of the electronic sheet or. I could actually move before (e.g. a piston race) because I did not give a constraint with offset, I left it free and he moved freely) so I wondered if this possibility of moving within the limits imposed of the electronic sheet is exploitable with the mouse movement.

Then there was another problem, of the series there is no 2 without 3! If for example I have two components connected between a pin, I impose a bond of coaxiality for rotation and coincidence in order to flow one above the other: so remains the degree of freedom of rotation of one respect the fixed one, what kind of bond do I have to use to tell him "place the two rods with an angle of 30 degrees between the flat faces? "

I was hoping to use offset in degrees between two floors but I can't do it. .of course having this offset in degrees I need in the electronic sheet as variable for animation

Hi.

hello good morning... so, the first part of the question.... It seems to me that you want to do as in sw, to tell the truth, I don't know if 2009 manages to move within a default range, I'm almost 100% sure that until 2007 the positioned piece never moved. you can set the max and min values from the sheet, but with the mouse it seems to me that you don't move anymore. Maybe with multiple positioning, but I don't guarantee you anything, I should try. the second part, it is not very clear to me, but perhaps if you add to the profile of the second particular angular quota between one profile and the other (maybe between reference lines) you should solve. Let me explain better, open the profile of the second detail, and add a quota between a profile line with a profile line of the first component. proof should work, also you will also have the angle to put on the movie. Bye.

I tried to make the quota as you suggested but it doesn't work, in the sense that goes wrong. Maybe I try to explain better with an example. I have a wheel hub with the brake caliper and I have a circle of a wheel. the first connection is coaxialized between the two components, in this way I have the free rotation of the wheel and the hub (fix).
then I give a coincidence between the faces of the wheel and the hub, now they are connected, the wheel can only turn.
now I want to give an angle between a race (a flat face) and a flat face of the clamp and then this angle makes it variable.

in a few words I do not see between the constraints of think the possibility to give a couple with angular offset. . .the idea would be to put paralellism and then "activate angular offset" but I don't know how to do

[Freddygol]

I don't remember, I should do some tests, but now I haven't td in my hand. Maybe some souls you're reading can respond quickly, otherwise we need patients so I see some solutions. Bye.

I found a way to do it. in practice I build a reference line of a certain angle compared to a reference axis: imposed the variable on this angle.
I now create a passing plan for this line and then put a parallel link between this created plan and the plan of the other component.
in practice by varying the variable on the straight one I can turn the mobile piece and the fixed one
