Problems solved by technology

[0003] At present, the shock absorbers for vehicles in the domestic market generally adopt hydraulic shock absorbers (or gas-filled shock absorbers) and mechanical adjustment methods. The common problems are "hardness", "abnormal noise" and "oil leakage". problems, and there are defects such as complex structure, slow response speed, narrow working frequency band, etc.

The system uses the magneto-rheological shock absorber to exhibit low-viscosity characteristics under zero magnetic field conditions, and presents high-viscosity, low-fluidity liquid characteristics under the action of a strong magnetic field, thereby changing the damping force and realizing vibration reduction control However, the current magneto-rheological damping systems all use single-chip or DSP processors. The resources inside the system of single-chip or DSP processors are limited, and they cannot be well connected with hardware and software platforms. Moreover, the ability to process data is weak
