Correcting Movement Deviation in Mechanical System Analysis
Explore the comparison between results from a pure Lumped Mechanical System and Multibody Dynamics analysis, identifying reasons for deviation in movement of components m1 and m2. Discover why the LMS and MBD methods may not align in certain scenarios, offering insights into enhancing model accuracy.

The Idea 1 Displacement Node 1 2 3 5 4 m2 m1 K2 K1 let s see how m1 and m2 move with the displacement excitation from node1
Perfectly Match! The result from the Lumped Mechanical System and Multibody Dynamics The result from the pure Lumped Mechanical System
The Idea 2 Displacement Node 1 2 3 5 4 K2 m1 m2 K1 C2 let s see how m1 and m2 move with the displacement excitation from node1
Big deviation for the movement of m2 The result from the Lumped Mechanical System and Multibody Dynamics , which is not correct in theory. The result from the pure Lumped Mechanical System , which is correct in theory.
Why it doesnt work with the LMS and MBD method at the model?
