Hi everyone,

I have a plate(217[mm]*40.1[mm]*1[mm]) which attached to a shaker and input frequency swept from (20:50 Hz)in 30 seconds. I tried to make a time dependent study using Comsol V5 select a 2D ,plate physics and input a prescribed displacement in z direction (thickness direction , out of plane) as a function of time and I get a wrong results. Hope some one give me a advice, thank you!
**Equation
k=(f1+((f2-f1)/30)*t)
A=g_const/k^2
Z=A*sin(k*t)
