Description
Technical field
The present invention relates to aircraft testing field, specifically a kind of energy absorption device for the load simulated test of airplane inertial.
Background technique
China requires to be increasingly enhanced to aeroplane performance, and the development of the relevant technologies must meet aircraft technology condition therewith.For
It ensures the integral strength and rigidity of aircraft, inertial load simulation test need to be carried out to aircraft.It carries out in simulation test procedure, examination
The process end of testing need to carry out energy-absorbing protection to testpieces, avoid testpieces from being destroyed under big inertial load, protection test part energy
Test of many times is enough carried out without damaging testpieces structure.
Currently, inertial load simulation test procedure end, is substantially the bullet constituted using the elastic parts that spring is constituted
Spring device carries out energy-absorbing protection to testpieces.After above-mentioned spring arrangement production molding, because the coefficient of elasticity of spring will not be sent out
Raw to change, spring arrangement absorbs energy ability after being compressed would not change, so the spring arrangement absorbs energy
Ability is unadjustable, is not able to satisfy the experimental performance requirement to different tests part；And spring arrangement bears big shock loading mistake
It is easy to produce radially bending deformation in journey, so that testpieces is born aperiodic transient load in moderating process, is unfavorable for testpieces
Deceleration demand.Testpieces slows down after stopping, and spring arrangement is in compression position, and spring will discharge elastic potential energy, elastic potential at this time
It can act on testpieces, move testpieces opposite direction, testpieces shakes back and forth, and testpieces cannot effectively slow down stopping,
The moderating process of testpieces effectively the true moderating process of simulation test piece, related data cannot not be able to satisfy test and need at this time
It asks.
Application No. is a kind of inertial load simulation test device and system, the inertia are disclosed in CN201710781299.2
Load simulated experimental rig mainly generates inertial load by elastic parts under the action of pull rod, and release inertia carries after pulling force disappears
Lotus keeps analog reslt more accurate using the simulation test device, to testpieces reality in disclosure of the invention simulation test
Apply the force application apparatus of inertial load power.
A kind of energy-absorption box for automotive field is disclosed in the innovation and creation of Patent No. 201410584848.3.Energy-absorbing
Box includes: installation frame, and the installation space of the length direction extension along installation frame is provided on the installation frame；Energy-absorbing group
Part, which includes the first friction portion and the second friction portion, and the first friction portion and the second friction portion contact energy-absorbing；It adjusts
Component is saved, which is arranged in the friction level that the first friction portion and the second friction portion are adjusted on installation frame.In fact
The mode of existing energy-absorbing is: under the action of lock shaft in holding down assembly of the first friction portion and the second friction portion, passing through regulation group
Part adjusts the compression degree to hold down assembly to energy-absorbing component.The innovation and creation are limited to the limitation in used field, and there are following several
Point is insufficient: 1. energy-absorption boxes are limited stroke by lock shaft, cause its damping retarding travel short, are unsuitable for big in inertial load test
Range demands；2. the compression degree in the first friction portion and the second friction portion is dissipated outward centered on lock shaft, coupling mechanism force by
Become smaller greatly, so the energy-absorption box fluctuates very severe above and below the active force during stop, stress is in energy-absorbing moderating process
State varying load does not meet the requirement of inertial load test；3. the energy-absorption box overall structure is suitable for running car collision process, because
It is far smaller than the quality and speed of aircraft for quality, the travel speed of automobile, the energy-absorption box is big used in having for being generated by aircraft
Property load testpieces impact under do not have energy-absorbing protection effect, so be not suitable for large impact caused by aircraft load
Lotus.Car crass occurred in moment, so the energy-absorption box in automotive field is suitable for the energy-absorbing under transient force effect, energy-absorption box exists
Rapidly crumple quickly absorbs buffering collision energy under the action of instantaneous impact force, and a degree of damage all occurs for automobile, thus
Protect the personal safety of interior driver and passenger.However, inertia test requires to test the Instantaneous Situation of part and the collision of energy-absorbing protective device
Counter-force cannot be greater than testpieces allowable stress, and protection test part will not be damaged after colliding with energy-absorbing protective device；And entire system
Dynamic moderating process testpieces uniform force, moderating process is approximate steady, so the energy-absorption box in automotive field is not suitable for and inertia
Test field, therefore it is required that design is suitable for the energy-absorbing protective device in inertia test field.
Currently, active force approximation constant of the hydraulic bjuffer in the market during stop, so moderating process is uniform
Slow down, for hydraulic bjuffer when absorbing big load, reaction force is larger, and the stroke of hydraulic bjuffer is shorter, does not meet
Experimental performance requirement；Other types of brake, damper, retarder are not able to satisfy test requirements document in the market.Test requirements document:
The Instantaneous Situation counter-force that testpieces is contacted with energy-absorbing protective device cannot be greater than testpieces rear end maximum load, and testpieces and suction
The Instantaneous Situation counter-force of energy protective device contact is adjustable；The aperiodic transition of duration cannot be carried in testpieces moderating process to carry
Lotus, moderating process are approximate steady；And testpieces must pacify after contacting with energy-absorbing protective device in the effective travel of 1000mm
Smoothly stop entirely.
It is therefore desirable to study a kind of adjustable inertial load simulation test energy-absorbing protective device of staged.

Frictional force adjustment plate bolt equidistant arrangement is drawn to make slide mass uniform force in housing cavity sliding, slide mass is not in up and down
Dancing, so that protection test part not will receive the active force swung up and down, testpieces is protected by energy-absorbing in whole process
Equipment safety smoothly stops.
First friction portion of automotive field energy-absorption box and the compression degree in the second friction portion are centered on single lock shaft
Diverging outward, from large to small, discontinuity fluctuation of the energy-absorption box during stop is very severe, and collision is slowed down non-for frictional force
Often rapidly, it is unfavorable for testing experiment result.If testpieces stop motion need to undertake varying load effect power, by adjusting every group of top
The screw-in degree of frictional force adjustment plate bolt make frictional force adjustment plate under the adjustment plate bolts effect of different groups of top frictional force by
Power is different, and monolith frictional force adjustment plate difference section is made to be capable of providing different normal pressures, and testpieces moderating process is presented approximate point
Section linear change.After testpieces stop motion, adjustment draws frictional force adjustment plate bolt and top frictional force to adjust plate bolt, makes this hair
It is bright to return to original operating state.
The present invention also has the characteristics that easy to operate, feasibility is high, good economy performance, adjustable and removable.
