Shock Absorber Essay

SUSPENSION:

In general suspension refers to suspending something in air i.e., acting as medium for two objects. In vehicle, sprung mass and unsprung mass are connected by shock absorbers and linkages, which are also part of suspension. Shock absorber is nothing but combination of damper and the spring.

It also includes
1. Camber angle
2. Caster angle
3. Toe angle
Camber angle:

Camber angle is the angle made by the wheels of a vehicle with the vertical line Positive camber: installing positive camber in a vehicle increases the controlling stability of a vehicle. Negative camber: installing negative camber in a vehicle increases the straight line stability of a vehicle and also decreases the steering

It does this by converting the kinetic energy of the shock into another form of energy. We used a shock absorber which compresses to maximum of 3cm.

Control arms: Control arms are mainly used for stability of vehicle and to reduce the impact forces to the damper. We have used double wish bone at front and swing arm at rear. And the material used is ASTM A106 grade ‘b’ seamless pipes of outer diameter 20mm and thickness 2mm, we opted it because, can withstand maximum loads applies on it and is light in weight when compared with others.

Knuckle:
Knuckle is used to connect control arms to the wheels. The material we have used is aluminium, the reason for choosing aluminium as it has ability to bear the forces acting on it and it is of light weight from available materials. The length of knuckle is assumed based on wheel base and track width. The design of the knuckle depends on braking torque, wheel load, perpendicular length of the knuckle etc. Knuckle that is being used is an integrated
