What are the factors which we need to consider before designing a suspension?

The most important of these are: Installation stiffness. Car packaging (aerodynamics, chassis structure and regulation requirements) Cg height….Other, secondary, priorities include – in no particular order:

• Cost.
• Ergonomics.
• Design resources.
• Motion ratio.
• Geometry.

What are the 4 components of suspension system?

What Parts Make Up the Suspension System?

• These are the only part of the suspension system that touches the ground.
• Coil springs. These are the part that absorbs the impact when a vehicle hits a bump in the road.
• Shock absorbers.
• Rods/linkages.
• Joints/bearings/bushings.

What are the requirements of suspension system?

Requirements of Suspension System

• There should be minimum deflection.
• It should be of minimum weight.
• It should have low maintenance and low operating cost.
• It should have minimum tyre wear.
• It should be of low initial cost.

What are hard points in suspension?

The hardpoints are the nominal centres of rotation of each of the ball joints etc that provide the articulation of the mechanism that forms the suspension. Typically we define these accurately at one particular ride height, and then hope we can work out where they go to as the suspension travels up and down.

What are the six basic functions of the suspension system?

The components of your car’s suspension system perform six basic functions:

• Maintain correct vehicle ride height.
• Reduce the effect of shock forces.
• Maintain correct wheel alignment.
• Support vehicle weight.
• Keep the tyres in contact with the road.
• Control the vehicle’s direction of travel.

What are the three types of suspension?

There are three basic types of suspension components: linkages, springs, and shock absorbers.

Are tubular control arms better?

The improved geometry helps the car track straight while heading down the road. The only way to accomplish this is by utilizing a tubular control arm where the geometry is built in. No amount of shims on a stock control arm will get the geometry corrected to modern standards.

What makes up a suspension system?

First, it was critical to understand the different components that make up a suspension system. These components consist of springs and shock dampers. Springs and shock dampers come in a variety of styles which are used on vehicles of all sizes. It is important to understand each to determine which is best for specific applications.

How can suspension design improve vehicle safety?

In addition, the system would not be limited to strictly passenger vehicles; it could also improve the performance of mobile robots, toys, or any mechanical system that requires a suspension for its functionality. Thus, this suspension design is expected to make broad contributions far beyond our goal of improving vehicle safety.

How to alter the geometry of the suspension system?

To alter the geometry of the suspension system, we utilize mechanisms to power instantaneous and independent motion in the linkage joints of the system. The position change of the linkage joints, as a result of the motion, occurs in the vertical (z) direction with respect to a predetermined origin (on a local nonrotating coordinate system).

What are springs in suspension?

Springs are considered the core component of all suspension systems. Springs carry the load that is applied to the vehicle and also absorb impact forces when traversing uneven terrain. Springs are elements designed to compress at a particular rate depending upon the application.
