Force-mechanism and fatigue properties under state.
Background technology
At present, high speed motor car technology high-speed develops, and automobile-used cement is widely used on EMU glass for vehicle window.Car
For window bonded structure after certain service life, can the intensity of vehicle window cement also reach requirement and the life security of passenger
It is directly related, therefore be highly desirable to study the fatigue aging characteristic of vehicle window adhesive, fatigue aging characteristic can lead to
Cross fatigue test and carry out checking analysis.
Analyzed with reference to the environment and stressing conditions of actual vehicle window bonded structure, vehicle window cement is mainly by temperature
The influence of humidity and alternate load.First, height EMUs range of operation is wide, often runs to south from the north, and temperature humidity becomes
Change it is big, vehicle window cement easily by temperature humidity change caused by environment fatigue.2nd, when EMU is being run at high speed at a high speed
Air-flow causes vehicle window, and by negative pressure, vehicle window cement is by the tensile load effect perpendicular to forms；When car body is static inside and outside vehicle window
Air pressure balance, vehicle window cement is not by the tensile load effect perpendicular to forms.The alternating change of vehicle window positive and negative air-pressure, causes car
Window cement is by the stretching alternate load effect perpendicular to forms.Therefore motor-car vehicle window cement master during the entire process of operation
To be changed by temperature humidity and be influenceed perpendicular to the stretching alternate load of forms.
When studying vehicle window cement fatigue and aging characteristics, due to that directly can not enter to whole motor-car vehicle window bonded structure
Row force analysis, its stress (alternate load) and working environment can only be simulated instead of vehicle window bonded structure by being bonded test specimen
The influence of (temperature humidity) factor.
Utility model team has applied for utility model patent to carry out fatigue test to bonding test specimen
201510598834.1, disclose a kind of multispecimen bonded joint creep test loading device, the device using arc lever and
