Rigid Body Dynamics

Industry relevance

Be it systems / mechanisms / components, when subjected to dynamic loads, develop acceleration and velocities and hence stresses. These have to be computed. to ensure the fundamental parameters such durability (fatigue life), reliability, controllability, observability and performance. The first step is to idealize the component to be rigid and derive all the dynamic loads seen by it and via load path loads seen by other components in the assembly.

Example: Loads on a rigid rotor and hence on bearings
