Solution for magnetorheological seat shock absorbers

The seat magnetorheological damper is an active damping device based on the intelligent characteristics of magnetorheological fluid, designed specifically to enhance passenger comfort. It effectively isolates the vibration energy transmitted by the vehicle chassis or mechanical platform by sensing seat vibration in real-time and dynamically adjusting damping force, especially suitable for seat systems in construction machinery, commercial vehicles, and high-end passenger cars.

Quick response

Millisecond level damping switching (<10ms), real-time vibration cancellation.

Wide damping range

The damping force can be adjusted to a ratio of 10:1 or more, suitable for complex working conditions.

load compensation

Automatically adjust the basic damping force based on the passenger's weight (such as increasing the initial damping during heavy loads).

Driving mode selection: Users can choose the "Comfort/Sport" mode, focusing on vibration filtering or support.

compact design

Structural miniaturization, suitable for limited seating space.

Low power consumption: Typical operating current<1A, suitable for vehicle electrical systems.


The seat magnetorheological damper upgrades traditional passive damping to an intelligent active adaptation system through closed-loop control of "perception decision execution". Its core value lies in:

Precise vibration isolation：

Key optimization for human sensitive frequency bands (1-10Hz)

Reduce the health risks of 'whole-body vibration exposure'.

Dynamic Comfort：

Balancing soft vibration filtering and impact suppression, surpassing the performance limit of mechanical/hydraulic vibration reducing seats.

With the decrease in the cost of magnetorheological materials and the advancement of control algorithms, such systems are penetrating from the high-end market to mass market models, becoming one of the key technologies for improving driving and riding quality.
