SECTION A Q1. An engine is connected to an unbalanced, rotating shaft as shown in Figure Q1. Viscoelastic shock absorbers are used to mount the engine to a frame. The engine is supported by rigid, frictionless guides that prevent it from moving in the horizontal direction. The shock absorbers can be modelled with a spring-damper system. The spring stiffness of the absorber takes on a value of k = 520 kN/m while its damping coefficient c is unknown. The entire engine-shaft assembly has a mass M of 35 kg. The equivalent mass of the shaft unbalance takes on a value of m = 1.2 kg at an offset distance r = 4 mm rotating at angular velocity w. The unbalanced rotating mass of the shaft results in a force F(t) acting in the vertical direction: F(t) = mw²r sin(wt). The force from the unbalance is causing vibration of the engine within the frame. Whenever the shaft is rotating at its operating speed of 1500 rpm the engine is displaced by a maximum of X = 0.3 mm.
