Description
Technical field
The invention belongs to a kind of MR damper, be specifically related to a kind of bar suspension type damper that has more.
Background technique
MR damper is a kind of intelligent vibration damping device, existing MR damper adopts magnetic flow liquid as working medium more, because magnetic flow liquid is liquid under the effect that there is no electromagnetic field, therefore, existing MR damper adopts piston and clutch release slave cylinder structure conventionally, and magnetic flow liquid is placed in to clutch release slave cylinder, by changing the size of electromagnetic field, change the viscosity of magnetic flow liquid in clutch release slave cylinder the damping force of its output is adjusted, because this class MR damper is difficult to be applicable to suspended load vibration damping, and its using scope is limited to, and of the present inventionly have more bar suspension type damper except being applicable to common suspension load, when damper rod is abundant, can also be applicable to the heavy load of hanging.
Summary of the invention
For existing piston magneto-rheological damper, for the deficiency that hangs load vibration damping, the present invention proposes a kind of novel MR damper, that is: a kind of bar suspension type damper that has more, technological scheme of the present invention is as follows:
Have more a bar suspension type damper, it comprises clutch release slave cylinder, damper rod and amortisseur bar; Wherein: clutch release slave cylinder is rectangle, rectangle clutch release slave cylinder is to have certain thickness rectangular frame, N+1 piece amortisseur bar, a N+1 damper rod and the two-sided bare electromagnet of N piece by two blocks of one side electromagnet, N+1 piece, by one side electromagnet, a block length quadra, two-sided electromagnet, a block length quadra, a two-sided electromagnet ... .. the mode of a block length quadra, an one side electromagnet is carried out overlapping and is fixed as one, and makes to form N+1 coffin in the N+1 block length quadra in rectangle clutch release slave cylinder; The middle part of a minor face below of rectangular frame have one with the through hole communicating in frame, sliding bearing is installed in through hole; Amortisseur bar consists of magnetorheological elastomer material, N+1 piece amortisseur bar is placed in respectively to N+1 coffin in rectangle clutch release slave cylinder, and a minor face above in one end of amortisseur bar and rectangular frame is fixed, the other end of amortisseur bar and one end of damper rod are fixed, and the other end of damper rod stretches out in rectangular frame by the sliding bearing on a minor face below rectangular frame; Described N is not less than 1 integer, the length of amortisseur bar is less than the length in rectangular frame and leaves the distance of the stretching of amortisseur bar, the width of amortisseur bar is less than the width in rectangular frame and leaves the free gap of amortisseur bar, the thickness of amortisseur bar is less than the thickness of rectangular frame and leaves the free gap of amortisseur bar, the width of one side electromagnet is not less than the width of rectangular frame, and the length of one side electromagnet is not less than the length of rectangular frame; On the magnetic pole strength of one side electromagnet, be evenly equipped with at least 4 pairs of magnetic poles, on each magnetic pole, be wound with field coil; The width of two-sided electromagnet is not less than the width of rectangular frame, and the length of two-sided electromagnet is not less than the length of rectangular frame; On two magnetic pole strengths of two-sided electromagnet, be respectively evenly equipped with at least 4 pairs of magnetic poles, on each magnetic pole, be wound with field coil; Damper rod and rectangular frame consist of non-magnet_conductible material; Damper rod is T-shaped, and the width of T-shaped damper rod upper end equals the width of amortisseur bar, the thickness of the thickness amortisseur bar of T-shaped damper rod upper end.
Function of the present invention is achieved in that clutch release slave cylinder is fixed on support, vibration source is hung and is fixed on a plurality of damper rods, when being positioned at the single, double surface electromagnet on clutch release slave cylinder rectangular frame two sides and not switching on, electromagnetic field intensity in clutch release slave cylinder in each coffin is zero, because there is no the magnetic line of force by each amortisseur bar consisting of magnetic rheology elastic body, each amortisseur bar now has lower elasticity when being subject to stretching, when being positioned at the list on clutch release slave cylinder rectangular frame two sides, after two-sided electromagnet energising, each is single, the electromagnetic field that two-sided electromagnet produces will make in clutch release slave cylinder the electromagnetic field intensity in each coffin higher, thereby make the elasticity of each amortisseur bar in coffin higher, therefore, by adjustment, be input to each list in clutch release slave cylinder, size of current in two-sided electromagnet is the intensity of the electromagnetic field in each coffin in capable of regulating clutch release slave cylinder, the elasticity size of the amortisseur bar in each coffin in clutch release slave cylinder is changed, make each damper rod drive each amortisseur bar damping force during each coffin in-draw in clutch release slave cylinder to change, thereby make the damping force that has more bar suspension type damper of the present invention controlled, because the present invention can carry out effective damping for suspended load vibration, thus, expanded the using scope of MR damper.
