Problems solved by technology
And when one electrode or two electrodes move, the unreasonable power supply method of the electrodes will easily lead to safety and reliability problems
[0003] After searching the existing technology, it is found that the Chinese Patent No.: 97200698.2 is a utility model patent named "Cylinder Electrorheological Shock Absorber". The entire piston rod of the shock absorber is a positive electrode. The longer the stretching stroke of the piston rod, the higher the The larger the voltage exposure area, which will cause electric shock safety problems
On the other hand, the electrorheological shock absorber in this patent makes the inner cylinder positively charged through the contact between the piston and the inner cylinder, and the reliability of the electrical contact between the two cannot be fully guaranteed due to the movable gap between the piston and the inner cylinder.

Description
technical field [0001] The invention relates to an electrode system in the electrical technical field, in particular to a positive electrode system of an electrorheological vibration isolator. Background technique [0002] Electrorheological fluid is a smart fluid material. Under the action of an electric field, it can instantly change from a liquid state to a solid state; after the electric field is removed, it can quickly return from a solid state to a liquid state. Using the rheological controllability of electrorheological fluids, a variety of electrorheological devices have been developed, such as electrorheological vibration isolators, electrorheological clutches, and electrorheological valves. Among them, electrorheological vibration isolators have been widely used in semi-active vibration control. So far, the electric field strength required for significant rheological effects of electrorheological fluids is generally above 2000V / mm. If the distance between the po...
