Description
Technical field
The invention mainly relates to fluid damping vibration isolation fields, refer in particular to a kind of damping modulation based on fluid velocity decomposition
Device.
Background technology
Damper modulator is a kind of intelligent vibration damping instrument, and the damper of the prior art is in the working cylinder full of damping fluid
Interior installation piston realizes the change of damping force using the working clearance of variable cross-section.Though the magnetic rheological liquid damper of the prior art
So realize variable damping, but there are still it is certain the defects of：The size that damping force relies primarily on the working clearance changes, and belongs to
It is adjusted in passive damping and the upper limit of damping force is less than normal.
The content of the invention
The technical issues of present invention need to solve be：For technical problem existing in the prior art, the present invention provides a kind of base
The damping force upper limit for decomposed in viscous fluid velocity radial and generate damping force device, having bigger, realizes and actively adjusts damping force
Damping modulator.
To solve the above-mentioned problems, solution proposed by the present invention is：A kind of resistance based on fluid velocity decomposition
Buddhist nun's modulator, it includes cylindrical resistance cylinders of boring, the cylinder body lid being installed on the resistance cylinders, through installing
Piston rod in the linear bearing that the cylinder body covers is installed in inside the resistance cylinders and is connected with the lower end of the piston rod
Piston modules.
The piston modules can be along being installed in inside the resistance cylinders and parallel to the piston rod axis direction
Lead free movement；80 percent space inside the resistance cylinders is full of damping fluid.
The inner wall of the outer wall of the piston modules and the resistance cylinders forms for damping fluid flowing, cross-sectional area
Constant working clearance, the principal direction of the working clearance and the axis angle of the piston rod are more than 15 degree.
Compared with prior art, the present invention having the following advantages that and advantageous effect：
The present invention it is a kind of based on fluid velocity decomposition damping modulator have the constant working clearance with it is constant
The coefficient of viscosity, using the working clearance with piston rod movement direction oblique so that the flowing velocity of viscous fluid radial direction produce
Lively amount, so as to fulfill the damper that damping is adjusted, when piston rod movement speed increase, radial momentum increases, so that
Damping force dramatically increases.It follows that the damper of the present invention has the damping force upper limit of bigger, and the size of damping force and work
The movement velocity of stopper rod realizes the effect for actively adjusting damping force into increasing function.
