In heavy vehicles such as trailers, and construction machines, the comfort of the driver's seat is particularly important because the driver is required to perform long-term, high-strength vehicle driving or mechanical operation. Most of the existing vehicle seats are cushion sponge buffering and spring vibration absorption, or stepped vibration absorption based on an air spring structure, or stepped vibration absorption based on a hydraulic system. The vibration reduction modes for improving the comfort of the driver seat are all passive, namely, the aim of vibration reduction is achieved only through the mechanical structure design mode of the seat. Currently, active damping systems based on electromagnetic structures are used only in very few models of passenger cars.
Various passive seat vibration damping modes on the existing heavy-duty vehicle only utilize a mechanical structure form to passively dissipate seat vibration energy, the instantaneous states of the vehicle and the seat are not detected and analyzed, and the direction and the size of the optimal vibration damping force which should be provided by the vibration damper at each moment are not calculated through the states of the vehicle and the seat. Under such passive damping conditions, the damping capabilities of the seat are not as effective as the desired effect of the seat system, and such passive damping is only effective over a specific, relatively small range of vibration frequencies. The driving under various road conditions such as a grade road, an earth road, an off-road and the like of the heavy vehicle can not be well adapted to various driving conditions, and the driving comfort of the heavy vehicle is also poor under some driving conditions. Therefore, the improvement of the passive seat damping mode has wider requirements, and the improved design of the structural form has great innovative research space.
