A Secondary Structure Inerter with Adjustable Coefficient of Inertia

Abstract

The invention discloses a two-stage-structure inerter with an adjustable inerter coefficient. The two-stage-structure inerter with the adjustable inerter coefficient comprises a hydraulic cylinder, aninertia force generator A, an inertia force generator B, an upper piston rod, a lower piston rod, a communicating pipeline and a blocking channel. Spiral grooves are formed in outer walls of the inertia force generator A and the inertia force generator B; a spiral groove rotating direction of the inertia force generator A is opposite to a spiral groove rotating direction of the inertia force generator B; and compared with a one-stage-structure inerter, according to the two-stage-structure inerter, through arranging the two upper and lower inertia force generators, the inertia force generatorA and the inertia force generator B are not connected directly, and when energy generated by the vibration of a vehicle wheel is provided to the inertia force generator B, the vibration is converted into energy for flowing of liquid in a lower cylinder, and the vibration of the vehicle wheel cannot be directly transmitted to a vehicle body through the inerter, so that the influence of the vibration of the vehicle wheel on the vehicle body can be greatly reduced.

Description

Technical field [0001] The invention relates to the technical field of vibration reduction and vehicle suspension, in particular to a secondary structure inertia container with adjustable inertia coefficient. Background technique [0002] With the continuous development and improvement of automobile manufacturing technology, people have higher and higher requirements for car ride comfort, and more people pay attention to the problem of car vibration. At this stage, cars mainly use shock absorbers to alleviate the impact of car vibration on ride comfort. In addition to improving ride comfort, the use of shock absorbers can also reduce the loss of other parts of the car and extend the service life of parts. Therefore, the research on shock absorbers has become a hot research in the automotive field. So far, there have been many researches on shock absorbers at home and abroad. Most of the shock absorbers used on the market are spring shock absorbers, hydraulic shock absorbers, ai...
