Figure 5
This diagram presents a mechanical system comprising two masses, labeled M and Mc, positioned between multiple springs and dampers. The left mass, M, is connected to a spring (K) and a damper (B) on the left side, while the right mass, Mc, is linked to another spring (Kc) and a damper (Bc) on the right side. The midpoint between the two masses contains an additional spring (Ke). Arrows indicate reference displacements, xr for the first mass and xc for the second. A force F_r is applied to the left mass, denoting the input to the system. The layout organizes the components sequentially, demonstrating the relationships between the forces, mass movements, and elastic properties within the system. The structure highlights the interactions through the spring and damper elements, essential for understanding the dynamic behaviour of the entire system.Equivalent two-mass spring damper system
