I 'd propose some adjustments to the functions x(t) and y(t)
[MATH]x(t):eval(r*(sin(θ(t))-θ(t)*cos(θ(t))))[/MATH]
[MATH]y(t):eval(r*(cos(θ(t))+θ(t)*sin(θ(t))))[/MATH]
The differential equation does not account for h, therefore it is correct only for h=0 (rigid bar with no thickness).

Thank you,Martin! Your comments are absolutely correct.
I really made a mistake, you have corrected.
Workheet updated. Thank you again.

I should add that the equations of motion of the center of the rod obtained by Martin, are the parametric equations of the involute, which corresponds to the physical meaning of the problem.

Fluctuations of three loads
(Ali H.Nayfeh,Dean T.Mook,Nonlinear Oscillations,1995)
The system consists of two extreme loads mass m1 and medium load mass m2 (2m1> m2). If the average load deviate from the equilibrium position, the system begins to oscillate

Неваляшка(Roly-poly)
The idea is taken from the site
http://demonstrations.wolfram.com/RockingRolyPolyToy/
The center of mass is below the center of rotation of the body
