Dynamics RB

DynamicsFEicon 180


Dynamics of Rigid Bodies application gives opportunity to play with parameters of typical mechanical dynamics problems such as nonlinear pendulum, mass-spring-damper system and projectile motion of a baseball ball. Animations and xy graph plots are given to have better understanding. Optional linear and non-linear problem configurations serve different level of users.  Characteristic parameters of equations  are given in animations for special testing purposes.

Users can create and email pdf (screenshot) and cvs data.

4th order Runge Kutta solutions are used in reported results. Users are able to alter parameters and precision of the numerical method in every case. 

Case 1: Pendulum in fluid friction (air)

Linear case can be set by just setting fluid friction is equal to zero.

Duration and number of steps determine the step size by which you can adjust accuracy.

Case 2: Mass-Spring-Damper system

Damping Ratio and undamped natural frequency are given in animation view for experimenting special cases such as critical damping resonant frequencies etc.  

Duration and number of steps determine the step size by which you can adjust accuracy.

Case 3: Projectile motion of a baseball ball in air.

Linear case can be set by just setting drag coefficient (Cd) is equal to zero.
