Frequency calculation

1) I) Rear sprung mass frequency based on wheel base and speed will be 1.358 Hz, time lag because of wheel base and speed is 0.10 sec.

II) Front sprung mass frequency at design condition 1.131 Hz

III) Front Spring rate 23.853 N/mm

IV) Rear Spring rate 27.711 N/mm

V) Front sprung mass frequency at Curb and GVW are 1.221 Hz and 1.127 Hz respectively.

VI) Rear sprung mass frequency at Curb and GVW are 1.612 Hz and 1.248 Hz respectively.

VII) Front unsprung mass frequency at all three conditions is 8.698 Hz

VIII) Rear unsprung mass frequency at all three conditions is 10.73 Hz

IX) Rear/Front frequency ratio at Curb, Design and GVW condtions are 1.32, 1.180 and 1.107 Respectively.
