8. BRAKE:
• The Type of brake used in this vehicle is disc brake of APACHE RTR 160.
• The CAD model of the brake is made in SOLIDWORKS 2016 and its
analysis and its thermal analysis is performed on ANSYS WORKBENCH
Brake Disc Calculation
Mass of the vehicle = 230kg
Initial velocity (u) = 11.11 m/s
Final velocity (v) = 0 m/s
Brake rotor diameter = 0.13m
Coefficient of friction between pad and rotors (γ) =0.3
Percentage of kinetic energy that disc absorbs (90%) = K =0.9
Coefficient of friction for dry pavement µ = 0.9
Stopping distance S = u2 /2gµ = (11.11)2 /2*9.81*0.9
S = 6.99 m
Deceleration of vehicle a = v2 -u 2 /2*S
a= 02 -(11.11)2 /2*6.99
a = 8.82 m/s
Stopping time V =u + at
0 =11.11+8.82*t
t=1.25 sec
a. Energy generated during braking
b. K.E. =γ K* m (u-v)2 /2
c. K.E. =3832.56 J

10.  STEERING:
• The main function of the steering system is to guide the vehicle in desired direction as per the
requirement.
Steering Calculation
Wheel Base (L) = 64 inch= 1625.6 mm Front
Track Width (a) = 1220 mm
Rear Track width (b) = 1280 mm
Inner steering angle = ⍬
Outer steering angle =φ
Slip angle α = tan-1 (0.5*front track width
(a)/wheel base (L))
Slip angle α = 20.56º
According to Ackermann’s steering method,
Now, assuming⍬⍬ = 35º and α = 20.56º Hence,
cotφ – cot⍬⍬ = (b/L)
cot (φ) – cot (35) = 1280/1625.6
φ = 24.29º
Maximum Turning Radius
Sinα = w/R = a/R
Therefore R = a/sinα
= 1220/sin(20.56)
Maximum Turning Radius =3473.92mm
=3.473m
Minimum Turning Radius
Tanα = w/R = a/R
Therefore R = a/tanφ
= 1220/tan (20.56)
Minimum Turning Radius = 3252.65mm
= 3.252m

13.  Suspension:
• Suspension is one of the important part of the vehicle it allows relative motion
between the wheels and the vehicle the type of suspension used depends upon
low forces are transferred form the wheels to the chassis
• The points at which the wishbone is connected to the chassis is located by using
LOTUS V5 called as suspensions point.

14. Conclusion
 By the concept of hybrid technology, the problem of energy crises and pollution of
environment can be minimized.
 The model of chassis and body, hub , suspension, knuckle and disc plate is
designed by using solid works 2016 and cero parametric 2.0
 Analysis of chassis & body , hub , knuckle and temp analysis of disc brake had
been done by using ANSYS 16.2
 Suspension analysis had been performed by using LOTUS Software
 Based on result obtained dimension can be modified as per further requirement.
