Only adhesive intensity itself is tested, the test of adhesive strength is never carried out to the bonded joint after glass installation.
Content of the invention
Present invention seek to address that drawbacks described above, provides a kind of diesel locomotive cab front screen adhesive strength testing equipment
And test method.
In order to overcome defect present in background technology, the technical solution adopted for the present invention to solve the technical problems is：
This diesel locomotive cab front screen adhesive strength testing equipment, including experimental rig, channel-section steel and counterweight, the test dress
Placement channel-section steel is put, the counterweight is placed on channel-section steel, the upper surface of channel-section steel is higher by the upper surface of experimental rig, the diesel locomotive
The test method of cab front window glass adhesive strength testing equipment is：The test method includes that static load test and impact are carried
Lotus is tested：
The static load test：
The first step, it would be desirable to which the framework of detection is kept flat to experimental rig（3）Upper and reverse side upwards, fastening,
Second step, by two channel-section steels（2）It is placed on and is close on the glass of bonding site, and plane on framework is higher by,
3rd step, by counterweight（1）Put down gently and put channel-section steel（2）On, standing a period of time, period, observation was by pressure glass and bonding
The variable condition at position, after revocation load, checks whether glass bonding site occurs adhesive failure；
The scragging：
The first step, it would be desirable to which the framework of detection is kept flat to experimental rig（3）Platform on and reverse side upwards, fastening,
Second step, by least one and Different Weight grade sandbag successively from a certain height freely falling body, sandbag front
Clash into glass,
3rd step, checks the bonding site and glass that clashes into every time.
According to another embodiment of the invention, further include that the sandbag of the same weight grade must not test to be less than
3 times.
The invention has the beneficial effects as follows：This diesel locomotive cab front screen bonded joint adhesive strength experimental rig
After the bonding installation for simulating cab front window glass, dead load, scragging is carried out to which, verifies bonding site institute
The maximum load value that can be born, while verifying the reliability of joint design, serving preferable practical function, being that design is provided
Foundation.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention；
Wherein：1st, counterweight, 2, channel-section steel, 3, experimental rig.
Specific embodiment
Fig. 1 is the structural representation of the present invention, and in figure includes experimental rig 3, channel-section steel 2 and counterweight 1, puts on experimental rig 3
Channel-section steel 2 is put, the counterweight 1 is placed on channel-section steel 2, the upper surface of channel-section steel 2 is higher by the upper surface 3 of experimental rig, the diesel locomotive
The test method of cab front window glass adhesive strength testing equipment is：The test method includes that static load test and impact are carried
Lotus is tested：
The static load test：
The first step, it would be desirable to the framework of detection keep flat to experimental rig 3 and reverse side upwards, fastening,
Second step, two channel-section steels 2 is placed on and is close on the glass of bonding site, and be higher by plane on framework,
3rd step, putting down gently for counterweight 1 is put on channel-section steel 2, standing a period of time, and period, observation was by pressure glass and bonding site
Variable condition, revocation load after, check glass bonding site whether there is adhesive failure；
The scragging：
The first step, it would be desirable to the framework of detection keep flat to the platform of experimental rig 3 and reverse side upwards, fastening,
Second step, by least one and Different Weight grade sandbag successively from a certain height freely falling body, sandbag front
Clash into glass,
3rd step, checks the bonding site and glass that clashes into every time.
The sandbag of same weight grade must not test less than 3 times.
Implement row：
According to technique for sticking flow process and requirement, complete the bonding work of glass, carry out after the solidification of n days dead load and
Scragging：
Dead load pressure method checking adhesive strength：By need detection framework lie on experimental rig 3, framework reverse side to
On, framework is fastened by experimental rig 3, is then placed on two channel-section steels 2 and is close on the glass of bonding site, and is higher by framework 3
Upper plane, finally by the counterweight 1 of constant weight（Can be converted according to maximum vibration numerical value during locomotive operation）Put down gently and put channel-section steel 2
On, standing a period of time, period observation are checked glass bonding by pressure glass and the variable condition of bonding site after revocation counterweight 1
Whether position there is adhesive failure, and whether glass stands intact, you can judge that whether qualified its checking is.
Shock loading method verifies adhesive strength：By need detection framework lie on experimental rig 3, framework reverse side to
On, framework is fastened by experimental rig 3, by the sandbag of Different Weight grade successively from a certain height freely falling body n time, is to ensure examination
The repeatability of result is tested, the test of same weight grade must not be less than 3 times.
The sandbag of its frontal impact glass, each weight grade must be clashed into 8 times every time, must check after clashing into every time viscous
, such as there is no adhesive failure in socket part position and glass, glass stands intact, then rushing for this weight grade can be born in explanation bonding site
Hit, collect the result of the test of each weight grade above-mentioned, you can the most favourable opposition that can bear after determining the adhesive adhering glass
Hit load value.
This diesel locomotive cab front screen bonded joint adhesive strength experimental rig is by simulating cab front window
After the bonding of glass is installed, dead load, scragging is carried out to which, verify the maximum load that bonding site can bear
Value, while verifying the reliability of joint design, serves preferable practical function, is design there is provided foundation.
