For optimize maintenance quality and test method,coal mine motor CAT loading test apparatus is designed by hydraulic viscous driving technique and computer data acquiring-processing system.

Introduced a new implementing method for Loading cutting part with high power of shearer,and expound working theory of loading test,main components and main technical feature.

Through the loading test to the model,the stressing characteristics,failure process,feature,and the limit load of the bearing platform are analyzed to check the reasonable,safe and economic characteristics of using the space truss theory to design the underpinned structure.

The loading experiment system to moving machine with high velocity is described in this article.

The application of cast-in-site continuous box beam bracket in soft soil foundation reinforcement and load test;

Introduces the basic structure,working principle,trait,load method and control,testing data gathering,export and display of shearer draw part direct current power return to load test bed.

In order to increase the rigidity of GRP,this paper proposes the method of adding strengthened reinforcing steel bar,carries out load test on GRP I-beam added with strengthened reinforcing steel bar,and shows by the test that its elastic modulus has been improved.

Testing purpose,model total layout,section design principle,joint structure,construction stages simulation,support design and loading in test were given in detail.

With the rapid development of science and technology, different new materials and motive power elements are developed, experiment studies must be done under the condition of approaching real operating circumstances before they become mature products and are put into markets, all of those should be completed on loading test bench with high quality.
