1. Features of WDW-J electronic compression testing machine 1. This testing machine is mainly used for the static stiffness characteristic test of bogie rubber elastic side bearing and the static stiffness characteristic test of bogie rubber pad and other materials. 
Executive standard: double acting Technical conditions of elastic side bearing (Q/QC35-091-2000) 
Technical conditions of axial rubber pads for bogies (Q/QC35-092-2000) 
2. The test machine adopts a double-column frame structure, and the upper pressure plate is fixed on the top On the beam, the lower pressure plate loads the sample upward under the action of the drive screw, and the AC servo control and transmission system are installed in the lower part of the host. 
3. The AC servo speed control system of the testing machine controls the high-frequency response AC servo motor, drives the precision reducer, and drives the precision ball screw pair to perform the test, which can realize the large-scale adjustment of the test speed (0.5-50mm/min), the test process Stable and efficient. 
4. Adopt a special controller or microcomputer for the testing machine, equipped with Windows special software for rubber static stiffness test, test according to national standards or standards provided by users, and complete the setting of test parameters, control of the test process, and data collection during the test , Processing, analysis and display, control and measurement are precise and accurate. And statistically and process the test data, and then output and print various required test curves and test reports. 
5. Test content: 
side support: a. Normal temperature vertical static stiffness (25°±10°C) test 
b. Low temperature ( -40°C) Vertical static stiffness test (without temperature box) 
c. High temperature (+50°C) vertical static stiffness test (without temperature box) 
Shaft rubber pad: a. Single piece at room temperature (25°±10° C) Detection 
b. Single piece low temperature (-40°C) detection (without temperature box) 
c. Single piece high temperature (+50°C) detection (without temperature box) 
d. Normal temperature of the assembly (25°±10° C) Testing
