Question

PLEASE ANSWER FULLY

B2 (25 marks). Following preliminary evaluation of your numerical model, it is decided to investigate the pitch and heave motion of the vehicle under the extreme scenario when the dampers fail (c 0) to investigate the effects of coordinate coupling. You are asked to determine the natural frequencies (heave and pitch) of the sprung mass component as well as the corresponding mode shapes. The vehicle is modelled as follows: C.G m, J B With the following parameters: m- 300 kg, Jo 600 kgm2, l1 = 1.2 m, l2 1.8 m, ki 30 kN/m and k2 20 kN/m
