What is a magnetorheological shock absorber?
Magnetorheological shock absorber is a device absorbing shock that works by placing a magnetic field on a mixture of liquid oil and iron particles. Iron particles are attracted by a magnetic field and have lined up along the lines of the magnetic field that pass through the liquid. This creates a thick liquid that resists movement and can help reduce vibration and shock in various applications. These fluids are sometimes referred to as intelligent fluids because they change properties when the magnetic field is added or changed.
Rheology is the study of the effects of liquids and solids when exposed to movement or pressures. In liquids, they are primary characteristics that can be useful for controlling vibration, viscosity and shear stress. The viscosity refers to the thickness of the liquid and how it can withstand movement or flow. Stress voltage is a measurement of how the liquid resists, that it suddenly expands or moves, and also how the materials placed in the liquid can move if the direction is quickly pulled out.
The shock absorber is a term for a device used to reduce vibration, which is similar to shock absorbers used on vehicles to reduce the movement of suspension due to uneven road surface. Many shock absorbers and shock absorbers use oils of different thicknesses to reduce movement and protection of the device. When small iron particles are added to the oils, magnetic fields can affect iron particles and change the properties of the liquid.
Adding an iron-role mixture to a standard shock absorber and creating a magnetic field with an electric current creates a magnetoreological shock absorber. As the magnetic field increases, iron particles will increasingly resist movement and create higher levels of vibration damping. If the electrical controller is added together with the magnetic field control software, vibrations and protruding magnetoreological shock absorbers or ECT vehicles can be used quickly.
iron particlesIn the shock absorbers they are often coated with polymer to prevent them from holding together. Maintaining very small particles helps keep them suspended in oil and prevents them from settling on the bottom of the shock absorber. When the magnetic field is formed, the mixture becomes more solid than a liquid and is very resistant to flow or movement. If the oil is pushed through the piston inside the cylinder, the high viscosity can reduce the movement of the oil over small holes in the piston.
The shear voltage can be used by changing the piston on a number of boards submerged in the oil. The plates move back and forth in the liquid, and when the magnetic field is activated, the iron-olete mixture thickens quickly and becomes very resistant to the cut. If the plates are connected to a solid shaft coming from the shock absorber, the shaft can be attached to a vehicle or building foundation and provide a damping system.
The protection of the earthquake Becamn at the end of the 20th century. In the area of human development, it grew in areas where the potential of building damage was high. One technique was to separate the building from the groundWith rubber or other materials absorbing shocks that allowed a certain movement of the building during the earthquake. However, without any form of damping, the movement of building may be extreme and damage or complete failure may occur. Adding a system of magnetorheological shock absorber at the base of the building gave architects a way to reduce the movement of the building using a controllable system.
Vehicles were another area of interest for magnetic damping systems in the 20th century. The interest in passenger comfort and an increased level of safety systems has led to shock absorbers by means of magnetoriological shock absorbers to ensure variable suspension. The driver could choose the level of driving comfort using a selector that would tell the drivers how much magnetic field they create when the Vibration of Sensed. In addition, the security systems could detect a slip or a possible rolling situation and change the suspension behavior to act against it.
Military weapons were another area where magnetorheological shock absorbers couldyytnit the advantage. When the shock absorber was mounted on a large cannon, he could feel the projectile and activate to reduce the backward character. This not only reduced the wear of the weapon, but also in mobile tanks or ... shocks, shocks could reduce fatigue to soldiers shooting weapons.
