The document analyzes the harmonic response of a vehicle suspension system modelled as a two degree of freedom system with two masses, Ms and Mu, connected by springs Ks and Kt. The document provides values for the system parameters and material properties, applies a harmonic force F=500sin(ωt), and indicates the system will be analyzed at different vertices to determine the harmonic response.
