Embodiment Construction

[0020] figure 1 It is a structural schematic diagram of the present invention, including a test device 3, a channel steel 2 and a weight 1 in the figure, the channel steel 2 is placed on the test device 3, and the weight 1 is placed on the channel steel 2.

[0021] The height of the channel steel 2 is higher than that of the test device 3 .

[0022] The test method includes static load test and impact load test:

[0023] The static load test:

[0024] The first step is to place the frame to be tested flat on the test device 3 with the reverse side up and fasten it.

[0025] In the second step, place the two channel steels 2 on the glass that is close to the bonding part and is higher than the upper plane of the frame.

[0026] The third step is to lightly place the weight 1 on the channel steel 2, and let it stand for a period of time. During this period, observe the change state of the pressed glass and the bonding part. After the load is removed, check whether the glass b...

Abstract

The invention relates to the technical field of front window glass bonding of an internal combustion locomotive cab, and in particular relates to a device and method for testing the bonding strength of the front window glass of the internal combustion locomotive cab. The device comprises a test device body, channel steel and a weight, wherein the channel steel is arranged on the test device body; the weight is arranged on the channel steel. The test method comprises the following steps of static load test and impact load test. The device for testing the bonding strength of the front window glass of the internal combustion locomotive cab tests static load and impact load of the front window glass of the cab by simulating the bonding mounting of the front window glass and checks a maximum load value on a bonding part; meanwhile, the design reliability of a joint is checked, and a relatively good practical effect is achieved; a basis is supplied to the design.

Description

technical field [0001] The invention relates to a bond strength test, in particular to a test device and a test method for the bond strength of the front window glass of a driver's cab of a diesel locomotive. Background technique [0002] The installation method of the front window glass of the double cab HXN5, DF11G, SDD17, and SDD7 diesel locomotive cabs adopts the polyurethane adhesive bonding process, not the traditional mechanical fastening installation process. The bonding structure belongs to structural bonding. Adhesives and bonded joints are required to have high strength properties to ensure the safety of locomotives. In the past, the test of the bonding strength only tested the strength of the adhesive itself, and never tested the bonding strength of the bonded joint after glass installation. Contents of the invention [0003] The present invention aims to solve the above-mentioned defects, and provides a test device and a test method for the bonding strength o...
