摘要
Provided is a matrix type double parallel capillary tube shock absorber with a variable system natural frequency, wherein on a pipeline between oil supply ports of an upper oil compartment (14) and a lower oil compartment (16), a capillary tube parallel type damping associated section and a capillary tube parallel type system natural frequency associated section are successively connected from top to bottom; the capillary tube parallel type damping associated section comprises four capillary tubes connected in parallel, with each capillary tube being connected in series with a solenoid valve so as to control the operation of the capillary tube; the capillary tube parallel type system natural frequency associated section comprises four capillary tubes connected in parallel, and each of the four capillary tubes is connected in series with a solenoid valve so as to control the operation of the capillary tube; the diameter of the smallest capillary tube of the frequency adjustment section is much larger than the diameter of the capillary tube of the resistance adjustment section; and in a matrix type operation state table, the configuration value Smn of the solenoid valves of the frequency adjustment section is selected according to situations, and by way of changing the mass, the problem of the system natural frequency of a hydraulic shock absorber for a vehicle being not adjustable or having a small adjustable range can be solved. Further provided is a method for operating a matrix type double parallel capillary tube shock absorber with a variable system natural frequency.
