Anatomical analysis of spring shock absorber

About spring shock absorbers
In order to reduce the vibration and impact of the road on the vehicle, a spring is required to absorb the energy of vibration and impact. The spring is an energy storage element in the suspension, which consumes the energy that is unfavorable to the riding comfort and handling stability of the vehicle. The working principle of the hydraulic shock absorber is that when the frame and the axle reciprocate relative to each other, and the piston reciprocates in the cylinder, the oil in the shock absorber housing repeatedly passes through a narrow cavity from an inner cavity. The pore flows into another inner cavity. At this time, the friction between the pore wall and the oil and the friction within the liquid molecule form a damping force against the vibration, so that the vibration energy of the vehicle body and the frame is converted into heat, which is then absorbed by the oil and vibration It is absorbed by the device shell and then dispersed into the atmosphere. Simply put, it converts kinetic energy into heat. If the shock absorber runs continuously on the test bench for several minutes, the outer wall of the shock absorber oil reservoir will become very hot and even hot.
as the picture shows:
The stabilizer bar is made of spring steel and has a flat U shape. It is installed horizontally at the front or rear end of the car (cars with a car are equipped with horizontal stabilizers at the front and rear). The elastic stabilizer bar produces torsional internal moments that will hinder the deformation of the suspension spring, reducing the lateral tilt and lateral angular vibration of the body.
Leaf springs can be divided into symmetrical leaf springs and asymmetrical leaf springs. For symmetrical leaf springs, the distance from the center bolt to the center of the two ends of the lugs is the same as shown in (a), and the unequal leaf springs are asymmetrical leaf springs. (b). The leaf spring deforms under the action of load, and the friction between the pieces due to relative sliding can promote the attenuation of the vibration of the frame and act as a shock absorber.
