how to create the motion using expression in form of sine curve

RAMGANESH

Dear All,

 

I want to create the motion at translational joint in the form of sinusoidal curve of displacement 75mm

 

Kindly provide your guidelines

 

Thanks

Hi Ram,

 

You can use the curve to input the motion as sinusoidal curve.

 

1) Create a curve using Curve panel in MotionVIew (Math function)

2) Create a motion on the translational joint

3) In motion properties, change the Define by path to Curve and refer the created curve here.

Dear Sir,

 

i want to know how to build the expression for sine curve of displacement 75mm.   For example: 50sin[TIME] 

 

Thanks

Ram,

 

Do you have the expression for the motion?

 

If yes, you can directly give in motion panel.

Dear Sir,

 

I have created the motion using expressions but the model is simulating abnormally and can't find the error in the joints

 

Thanks

Ram,

 

Please share the sinusoidal curve and the model.

RAMGANESH

Dear Sir,

 

I have shared the model at your dropbox

 

Thanks

Hi Ram,

 

I dont see that this has something to do with the motion.

 

Plot the displacement graph for Rig and you will the motion is OK.

 

You may have to look into the joints in detail.

RAMGANESH

Dear Sir,

 

did you find any error in the joints?

 

Kindly guide me what corrections to do in the model

 

Thanks

Ram,

 

One of the joints is deactivated and I missed it. Sorry about that.

 

I dont see anything strange in the animation so far. The wheel is in plane with rig and moves in a translational direction as well as rotates around an axis.

RAMGANESH

Dear Sir,

 

Animation is ok but the wheel is rotating around the axis more know,is it not a problem?

 

Also i want to create the output request to measure the Toe angle?

 

Thanks

Ram
