First embodiment
Fig. 1 is the overall structure diagram for the winged control damping device 100 that first embodiment of the invention provides, and refer to Fig. 1.
A kind of winged control damping device 100 provided in this embodiment, for playing buffering, damping and fixed work to flying control box 101
With.Flying control damping device 100 includes vibration damper plate 110, the first pillar 120, the second pillar 130 and non-newtonian fluid buffer layer 140,
First pillar 120 and the second pillar 130 are respectively arranged on the both sides for flying control box 101.One end of first pillar 120 and vibration damper plate 110
Connection, the other end of the first pillar 120 are connected with flying control box 101.One end of second pillar 130 is connected with flying control box 101, and second
The other end of pillar 130 is connected with non-newtonian fluid buffer layer 140.
First pillar 120 and the second pillar 130 are elastic component.Preferably, elastic component uses spring.First pillar 120
For the first spring, the second pillar 130 is second spring.Certainly, it is not limited to that, the first spring and second spring can also be
Other elastic components.
In the present embodiment, the quantity of the first spring and second spring is respectively four.Four the first springs are evenly distributed on
Fly the one side of control box 101, for example, being distributed in four corners for flying 101 one side of control box；Four second springs are evenly distributed on winged control
The opposite side of box 101, for example, being distributed in four corners for flying control 101 opposite side of box.First spring and second spring are on winged control
Box 101 is symmetrical arranged.Non-newtonian fluid buffer layer 140 includes non-newtonian fluid and the container for housing non-newtonian fluid
160, the second pillar 130 is fixedly connected away from the one end for flying control box 101 with the bottom wall 161 of container 160.Second pillar 130 is complete
It is immersed in entirely in non-newtonian fluid, the part for flying control box 101 is also immersed in non-newtonian fluid.
It should be noted that at a certain temperature and in wider range of shear rate, fluid that k value is kept constant
Referred to as Newtonian fluid.In Newtonian fluid, shear stress and shear rate are linear, i.e., relational expression is
In formula τ be shear stress, unit Pa；For detrusion rate, unit s-1；μ is fluid dynamic viscosity, i.e., viscous
Degree.Viscosity unit is Pas (Pa Sec), and the shearing force under unit speed gradient suffered by fluid is equal on viscosity value.Nature
Middle many fluids are Newtonian fluids, such as the most of neat liquids of water, alcohol, light oil, low molecular compound solution and low speed
Gas of flowing etc. is Newtonian fluid.
And non-newtonian fluid is just the opposite, it refers to the fluid for being unsatisfactory for newtonian viscous experimental laws, i.e., shear stress with
It is not the fluid of linear relationship between shear rate.Its viscosity can change with the variation of shear stress and shear rate.Non- ox
The fluid that pauses is widely present among life, production and the Nature.For example, polyethylene, polyacrylamide, polyvinyl chloride, nylon 6,
PVS, celluloid, terylene, rubber solutions, various engineering plastics, the melt of chemical fibre, solution etc. are all non-newtonian fluids.For another example
A variety of body fluid such as blood, lymph, cyst fluid, the tomato juice in food industry, starch fluid, egg white etc. also belong to non-ox on the person
Pause fluid.
Non-newtonian fluid can be divided by two major classes according to the difference of shear stress and shear rate relation roughly：The first kind is non-
The attribute of Newtonian fluid is unrelated with time or shearing duration；The stress and strain relationship of second class non-newtonian fluid and shearing
Duration is related.Wherein, the non-newtonian fluid being unrelated with the time can be divided into Bingham fluid, pseudoplastic fluid, swollen plasticity stream again
Body, surrender-pseudoplastic fluid and surrender-dilatant fluid.Due to dilatant fluid have viscosity with shear velocity increase and
Increased characteristic, in shear-thickening effect, fluid performance " volume " slightly expands, and therefore, in this application, non-newtonian fluid is adopted
With dilatant fluid, the viscosity of dilatant fluid increases with the increase of shear rate, and dilatant fluid prevents object
The effect of shield damping is more obvious, and effect is more preferable.
Fig. 2 is Newtonian fluid and the shear rate of dilatant fluidWith the relational graph of shear stress τ.For non newtonian
Fluid without constant viscosity concept, has different apparent viscosities under different shear rate, this is the Yi great Te of non-newtonian fluid
Point.As shown in Fig. 2, figure cathetus represents Newtonian fluid, parabola represents dilatant fluid, and slope represents viscosity, mu.Newtonian fluid
Viscosity, mu keep constant, not with shear rateVariation and change, the viscosity, mu of dilatant fluid is with shear rate
Increase and increase.
Fig. 1 is continued referring to, the non-newtonian fluid with shear thickening phenomenon, colloidal particle is typically in dense pack
State is liquid/paste, and the water as decentralized medium is filled in the particle gap of dense arrangement.When unmanned plane is in low shifting speed
When under state, winged control box 101 is smaller to the impact load rate of non-newtonian fluid, and non-newtonian fluid is subject to smaller shearing at this time
Rate, slip and mobilization due to water, the viscous drag that non-newtonian fluid is shown are smaller so that non-newtonian fluid shows
Go out mobility, winged control box 101 at this time mainly fixes cushioning effect, the first spring and second by the first spring and second spring
Spring absorbs most of energy.And when unmanned plane moved under fast state in height, taking off landing or runs into impact,
Body is subject to larger impact loading at this time, and shock loading, which is transferred to, flies control box 101, the non-newtonian flow in container 160
Body is subject to the great shock loading of shear rate, and the ion in dense arrangement will be disturbed quickly, become mushy
Loose array structure.At this moment since original moisture can not fill up the gap between particle again, do not have between particle and particle
The slip effect of water layer, thus viscous drag will increase suddenly, and non-newtonian fluid is caused to become firm in itself, have viscoelastic
Property, the energy that extraneous transmission is come in can be absorbed to greatest extent, be not damaged so as to be effectively protected winged control box 101
It is bad, play the role of damping protection.
Second embodiment
Fig. 3 is the structural representation of the non-newtonian flow scapus 125 for the winged control damping device 100 that second embodiment of the invention provides
Figure, refer to Fig. 3.
In the present embodiment, the first pillar 120 and the second pillar 130 are using non-newtonian flow scapus 125, the second pillar 130
Also it is immersed in non-newtonian fluid buffer layer 140.Preferably, non-newtonian flow scapus 125 include locking clamping plate 147, buffer strip 145,
Waterproof clamping plate 143, cushion 149 and non-Newtonian fluid layer 141, the both ends of non-Newtonian fluid layer 141 connect waterproof clamping plate respectively
143, one side connection buffer strip 145 of the waterproof clamping plate 143 away from non-Newtonian fluid layer 141, buffer strip 145 is away from waterproof clamping plate
The one side of 143 (i.e. buffer strip 145 is away from non-Newtonian fluid layers 141) is connected with locking clamping plate 147.Cushion 149 is fixedly connected
In one side of the locking clamping plate 147 away from buffer strip 145.That is, waterproof clamping plate 143 is arranged on non-Newtonian fluid layer 141 and buffer strip 145
Between, buffer strip 145 is located between waterproof clamping plate 143 and locking clamping plate 147.
