1.Calculate the following parameters for the front and rear suspension: i.Sprung mass critical damping ii.Unsprung mass critical damping iii.Sprung mass initial damping coefficient iv.Unsprung mass initial damping coefficient v.Low speed compression damping coefficient vi.High speed compression damping coefficient…

    This challenge tests understanding of the concept of flat ride 1.Calculate the following parameters. Use the same front and rear spring rates for all three load conditions.         The front sprung mass natural frequency target at design is 1.15 Hz. Keep this fixed…

1. Wheel Rate is basically the spring rate but measured at the wheel instead of the where the spring attaches to the linkage.     Wheel Rate = Spring Rate * (Motion Ratio ^ 2) * Spring Angle Correction     The motion ratio is the ratio between how much the spring is compressed compared to how much…

1. Geomteric Parameters calculations: Caster(`theta`) =`tan^-1` [UCA_KBJ_X/(UCA_KB_Z - LCA_KBJ_Z)] Mechanical trail = tan(`theta`)*(LCA_KBJ_Z)  KPI(`phi`) = `tan^-1`[(UCA_KBJ_Z -LCA_KBJ_Z)/(UCA_KBJ_Y-LCA_KBJ_Y)]  Scrub Radius = WC_Y - [tan(`phi`)*LCA_KBJ_Z]-LCA_KBJ_Y  KP Lat offset or…
