CALCULATIONS

The reaction forces acting on one front wheel of the vehicle are calculated using the following parameters:

m	Mass	2840 Kg
G	Load of vehicle	27860.4 N
B	Track	1.496 m
H	Height of CG	0.8 m
L	Wheelbase	2.425 m
Lf	Distance from Front Axle to CG	0.97 m
Lr	Distance from Rear Axle to CG	1.455 m
v	Velocity of vehicle	11.11 m/s
R	Radius of road curvature	25 m
β	Banking angle of road	4 0
α	Slope of road	10 0
µ	Co-efficient of friction	0.6
a	Deceleration due to braking	6.17 m/s2
δ	Angle of upper control arm	15 0

LOADS 

For static loading

static loading on one wheel on the front axle will be =  8358.12N

For braking

The load on one wheel at the front axle  =  11249.79 N                         

For cornering

during cornering the loading on one wheel on the front axle is around =   20814.619 N ( inner wheel)

 

For down hill travel

The loading on one wheel during down hill travel will be  =  9029.1 N

Force On Control Arms

The reactions obtained for the control arms are:

Bx	By	Ax	Ay
-2691.1079	-7637.04	-2691.107989	-721.08

Calculations for dynamics:

modulus of resilience= 491504.8544 J/m³

Strain Energy Limit for (Lower/upper) Wishbone = Modulus of resilience × Volume of part

For lower=268.58 J/m³

For upper=134.67 J/m³

                       ............values are lower
