How shock absorbers are manufactured?
First, raw steel arrives and is made into shock and strut tubes and rods. Then, manufacturing cells cut, stamp and weld components used downstream. The steel begins its course through heat treating, quenching, grinding and threading to yield a hardened shock rod that meets our OE quality standards.
What are the basic considerations you have to keep in mind while designing a suspension system?
The most important of these are: Installation stiffness. Car packaging (aerodynamics, chassis structure and regulation requirements) Cg height.
What is the basic operation of a shock absorber?
All hydraulic shock absorbers work by the principle of converting kinetic energy (movement) into thermic energy (heat). For that purpose, fluid in the shock absorber is forced to flow through restricted outlets and valve systems, thus generating hydraulic resistance.
What are the 4 types of suspension system?
Modern springing systems are based on four basic designs. Get to know these four spring classes: leaf springs, coil springs, torsion bars, and air springs.
What is suspension compliance?
Compliance steer is a metric to measure the amount of self steer generated by a suspension system when it is subject to a cornering (lateral) load at the contact patch. Compliance steer is measured as degrees of toe change per Kilo-Newton of force at the contact patch, Deg/kN.
What material are shock absorbers made of?
Shock absorbers and dampers are generally made of high-strength steel to handle the pressures from the internal hydraulic forces. Elastomeric seals prevent the fluid from leaking out of the cylinder, and special plating and coatings keep the units protected from harsh operating environments.
What are the parts of a shock absorber?
A twin-tube shock absorber consists of an inner and outer cylinder. The inner cylinder contains oil and the piston rod is connected to the piston valve….This gas acts like a balloon and absorbs vibrations.
- Basic Twin-tube.
- Twin-tube Gas Charged.
- Positive Sensitive Damping.
- Acceleration Sensitive Damping.
- Coilover.
How do you calculate motion ratio in suspension?
The equation is WR = SR(MR)2, WR is wheel rate in LBf/in, SR is the spring constant (also known as k) in LBf/in, and MR is motion ratio where MR is stated as shock position/wheel position. For reference, the front wheel rate of a F355 Challenge car is 1,078 LBf/in with a 2200 LBf/in spring!
What is suspension and shock absorbers?
Answer: Shock absorbers are an integral part of a vehicle’s suspension. A shock absorber is designed to absorb or dampen the compression and rebound of the springs and suspension. They control the unwanted and excess spring motion. Shock absorbers keep your tires in contact with the road at all times.
Which type of suspension is best?
Multi-link and dual wishbone systems are the holy grail of suspension designs, allowing engineers to achieve agile handling without compromising ride quality.
What is structural analysis in shock absorber design?
Structural analysis is done to validate the strength a nd modal analysis is done to determine th e displacements for different fre quencies for number of modes. Comparison is d one for two materials to verify best material for spring in Shock absorber. Modeling is done in Pro/ENGINEER and analysis is done in ANSYS.
What are the different types of shock absorbers?
Existing shock absorbers can be divided into two classes based on the type of the spring being used: those using a solid spring made of steel or rubber and those using a fluid spring with gas or oil, or a mixture of the two that is generally referred to as oleo-pneumatic.
How does a shock strut work?
This type of shock strut absorbs energy by first forcing a chamber of oil against a chamber of dry air or nitrogen and then compressing the gas and oil. During the compression process, the oil and gas either remain separated or are mixed depending on the type of design.
What is a suspension system?
SUSPENSION SYSTEM The suspension of vehicles needs to satisfy a number of requirements which depend on different operating conditions of the vehicle (loaded/unloaded, acceleration/braking, level/uneven road, straight running/ cornering).
