Low zero field viscosity

Under zero magnetic field conditions, it has a very low viscosity, which is beneficial for the actuator to obtain the lowest possible lower limit of the adjustment force value

Good anti settlement performance

Low settlement rate after prolonged standing and no hard settlement will occur

High yield strength

Under the action of an external magnetic field, it has a high yield strength, which is beneficial for the actuator to obtain the highest possible upper limit of the adjustment force value

Good viscosity resistance

No IUT (thickening) phenomenon occurs after long-term use

Good temperature tolerance

Can be used normally for a long time within the range of -45 ° C to 130 ° C

Good aging resistance

Long term use is not prone to aging due to factors such as oxidation, temperature, light, mechanical force, etc

Products and Services

As a pioneer in the field of magnetorheological intelligent suspension in China, COSMARTOR International adheres to independent innovation and has achieved full stack self-developed core products, including magnetorheological fluid, magnetorheological intelligent suspension system, and suspension controller software and hardware. It is the only intelligent suspension system supplier in the world with a complete MRF+MRD+ECU+SW technology chain and mass production experience.

The high-performance magnetorheological fluid developed by the company has low zero field viscosity, high yield strength, good dispersibility after long-term standing, strong compatibility with the valve core, and good fluidity even at minus 40 degrees Celsius.

The intelligent suspension electronic controller (ECU) developed and designed by COSMARTOR International has vehicle grade reliability, adopts optimized SH-ADD control algorithm, and features full frequency band optimization control, millisecond level fast response, and low energy consumption.

Adopting full stack self-developed magnetorheological technology, the flow characteristics of magnetorheological fluid are controlled by electromagnetic field, and the damping force is adjusted in real time. Whether in the city or wilderness, using magnetorheological intelligent suspension eliminates bumps and rough road surfaces, providing drivers with appropriate support and buffering

By perceiving and controlling the body posture in milliseconds, the ultimate driving experience of the entire vehicle is achieved. MRD uses electromagnetic coils to control the magnetic field and change the damping force generated by magnetorheological fluid chaining. The damping adjustment range is greatly improved, with low noise, fast response, high durability, and a 50% increase in anti pitch and roll effects. It is currently known as the fastest responsive active suspension.

Has fast response speed. Magnetorheological suspension achieves the fastest real-time sensing and control speed among known intelligent suspensions, with a response speed of up to 1000 times per second.

Good handling stability, effectively suppressing pitch vibration, forward and backward movement, and roll motion. The magnetorheological suspension adjusts the suspension damping value thousands of times per second, enhancing support during cornering, increasing tire lateral grip, and reducing body roll and pitch.

High precision control. By using a magnetic field to change the magnetorheological fluid, precise control of damping is achieved. It can make the most accurate control for different road conditions.

High driving comfort. Magnetorheological suspension has significant advantages in filtering out low-frequency vibrations and high-frequency road noise of the vehicle body. Faced with bumpy roads or speed bumps, the magneto rheological intelligent suspension can effectively filter vibrations, greatly reducing the discomfort of passengers in the car, and providing a smooth driving experience for passengers like walking on flat ground.
