Format for Equation-Defined Force

Hello,

I'm trying to simulate a bearing load on a cylindrical hole. I've defined a cylindrical coordinate system in the hole and associated a semi-circles's worth of nodes with it (although I am unable to use these particular nodes later when I define the way the load acts, strange). I want to model the load using a cosine function so I can maximize the effective force along the line of application. What kind of syntax and definition of variables is Hypermesh looking for when I develop an equation to represent a distributed load? I'm using Nastran for analysis FYI.

Thanks,

Hi,

a very simple equation as example (Analysis->Force->nodes->switch to equation)

type in: cos(x)

So you can define the magnitude of the forces as cos(xlocation)...

So which means 'sin(x)' x- magnitude, will be my equation for my sinusoidal bearing load?

When I created an equation and applied to particular nodes but its taking as a unit load only.

How can we I give a loading equation ?

Can you please replay for my doubt?

if you type 'sin(x)' in magnitude then it is unit load only

you should type in magnitude as '10*sin(x)' số load is tên time
