Abstract
The utility model discloses a no compensation-type single piston rod magneto rheological damper, comprising a cylinder. In a casing of the cylinder is disposed a piston, which is connected with a piston rod and is provided with grooves thereon. In the grooves are winded excitation coils in connection with a lead, which transverses the piston and the piston rod to be connected with a controller. The cylinder is filled with magneto-rheological fluids therein. A gap is arranged between the piston and the inner wall of the cylinder. The front and rear ends of the cylinder are respectively provided with a front end cover and a rear end cover. The piston is provided with a stoke hole. A guiding rod is disposed in the cylinder, wherein one end of the guiding rod is connected with the rear end cover and the other end is located in the stroke hole of the piston. The no compensation-type single piston rod magneto rheological damper of the utility model is simple in structure, convenient in installation, low in cost and good in controllability and enables to enhance orientation and mechanical properties of a single piston rod magneto rheological damper and to simplify the structure of the single piston rod magneto rheological damper.
Description
Technical field
The utility model relates to engineering damping (shaking) field, relates generally to the uncompensated formula single outstretch pole magnetorheological damper that a kind of steering capability is good, do not need pressurizer.
Background technique
MR damper is a kind of change damping controller of function admirable, has advantages such as the damping force adjustable extent is wide, the rapid and required little energy of response, is the ideal device that structure is implemented half ACTIVE CONTROL.In field of civil engineering, based on half ACTIVE CONTROL of MR damper wind high-rise, bridge structure shake and Seismic Response Control in existing more application.
Single outstretch pole magnetorheological damper is simple in structure, not limited by installation direction, in limited installing space, has bigger stroke, has broad application prospects in fields such as machinery, automobile and civil engineerings.Traditional single outstretch pole magnetorheological damper guidance quality is relatively poor, particularly for the damper than big stroke.
In addition, during the single outstretch pole magnetorheological damper motion,, the Volume Changes that pressurizer comes compensating piston bar turnover oil cylinder that liquid is caused need be set because piston rod turnover oil cylinder can produce the Volume Changes of oil pocket.The pressure design of compensator is extremely important, and pressure is too big, makes damper compression damping power increase; Pressure is too little, can not normally compensate flowing of magnetic flow liquid, makes damper show that the merit characteristic distorts.Exactly because traditional single outstretch pole magnetorheological damper need be provided with compensator, restricted the application of single outstretch pole magnetorheological damper to a great extent.
Summary of the invention
The purpose of this utility model provides the uncompensated formula single outstretch pole magnetorheological damper that a kind of steering capability is good, stroke is big, need not volume compensation.
The purpose of this utility model can adopt following technological scheme to realize: described single outstretch pole magnetorheological damper comprises cylinder barrel, piston and piston rod, piston is arranged in the cylinder barrel, piston links to each other with piston rod, piston is provided with groove, twine field coil in the groove, field coil links to each other with lead, and lead passes piston and links to each other with controller with piston rod; Fill magnetic rheological liquid in cylinder barrel, piston and inner wall of cylinder are provided with the gap, are respectively arranged with the damping end cap at the forward and backward two ends of cylinder barrel; Piston is provided with the stroke hole, is provided with a guide rod in cylinder barrel, and an end of guide rod is connected with rear end cover, and the other end is positioned at the stroke hole on the piston.
It is identical that described guide rod external diameter and the external diameter of piston rod are provided with, and when making piston rod turnover oil cylinder, can not produce volume differences in the oil pocket, thereby need not to be provided with pressurizer.
The utlity model has following characteristics:
(1) on the end cap of single outstretch pole magnetorheological damper, guide rod is set, has improved the guidance quality of damper.
(2) guide rod and the external diameter of piston rod are provided with identical, when making piston rod turnover oil cylinder, can produce volume differences in the oil pocket, thereby need not to be provided with pressurizer, simplified the structure of single outstretch pole magnetorheological damper.
In sum, the utility model is simple in structure, easy for installation, cost is low, and controllability is good, can improve the guidance quality and the mechanical property of single outstretch pole magnetorheological damper, has simplified the structural type of single outstretch pole magnetorheological damper.Fields such as mechanical vibration, earthquake engineering and blast impulse vibrations in big stroke of needs and higher damping (shaking) effect have comparatively wide application prospect.
