Description
Technical field
The utility model is related to a kind of vibration test frock, and in particular to a kind of fuel-oil pump governor vibration test frock.
Background technology
Gas-turbine plant in use usually can it is vibrated with impact etc. dynamics environment load effect, this
Kind of effect often result in device in equipment occur fastener loosen, solder joint fracture, riveting failure, or threaded connection failure etc..
These failures are likely to result in huge economic loss, and casualties.
Pertinent literature is introduced, and electronic product accounts for total crash rate because of the crash rate that the dynamics environments such as vibration, impact cause
28.7%, in order to ensure the safety and reliability of equipment.Therefore, in these equipment investments using preceding needing to the ring residing for it
Border load is simulated analysis, to diagnose the failure that may occur, improves equipment dependability, reduces unnecessary economic damage
Lose.So the frock for meeting vibration environment test requirement is a key of guarantee test quality.
With science and technology continue to develop, the requirement of working environment is more complicated, and performance requirement is higher, thus vibration ask
Topic becomes increasingly conspicuous.Traditional structural design method based on static criterion far can not meet modern gas turbines structure will
Ask, it is impossible to ensure the safety and reliability of its work.It is to meet modern gas turbines structure design using dynamic structure design
It is required that effective ways.The vibration balancing of control structure is reached by dynamic design, improves the quality of product, improve its safety
Reliability, this also will be the developing direction of gas turbine structure designing technique.
Vibration test is one of important content of dynamic environmental test, when fuel-oil pump governor works on gas turbine,
It is in an ambient stress complicated and changeable, around under the influence of environment, the reliability and ring of fuel-oil pump governor work
Border adaptability can be varied from, and in order to simulate stressing conditions of the fuel-oil pump governor in real work, be adjusted exclusively for fuel pump
Section device design vibration test special tooling, giving corresponding load value carries out verification experimental verification, and fuel-oil pump governor is by vibration
After experiment, the success or not of this experiment is judged according to result of the test to evaluate the reliability and environment of fuel-oil pump governor
Adaptability.When vibration test is carried out to product, in most cases be with frock test product clamping on a vibration table.
During experiment, due to having used frock, the energy of shake table and motion are directly delivered on product, but are first delivered to frock
On, then by tool equipment transmission to test product.Therefore, the design of frock be in vibration test one it is extremely important, must
Few link, the success or not of experiment, the credibility of result of the test, is processed and installs and uses water at design with test tool
It is flat closely related.
But the design of vibration test frock is the larger work of a difficulty, often ever-changing by test specimen, fixture must
Must adapt to and meet this change.From the Description of Related Art that domestic open publication and open channel understand, except to fixture
Propose outside basic demand, China has not yet been established specific standard.At present, the domestic importance most attention to test tool is not
Enough, some personnel only with feeling to carry out design fixture, lack necessary calculating and analyze during design, do not carried out in structure rational excellent
Change, verification test that also there is no need etc..In view of above-mentioned present situation, the design of current fixture is primarily present following shortcoming：
（1）Often there is very big distortion in the vibration of fixture transmission.
（2）The vibration value of each point differs greatly on fixture, and the uniformity is very poor.
（3）In test frequency range there is multistage resonance in (5Hz~2000Hz), and vibration control is extremely difficult.（4）Clamp material
From improper, quality is excessive, and consumed energy is more.
For above-mentioned deficiency, it is necessary to design and develop a kind of fuel-oil pump governor vibration test frock, can supply above-mentioned
Each shortcoming.
