Universal Testing Machines

Computer Controlled Light Alloy Wheel Rolling Bend Fatigue Testing Machine

Standard Executed:

• QC/T211-1996 Test method for light alloyed wheel of Motorcycle and Portable Motorcycle
• QC/T212-1996 Aluminium alloy Integrated wheel Universal technique condition of Motorcycle and Portable Motorcycle
  

Main application:

It is mainly used to do rolling bend fatigue testing of Motorcycle or Light Motorcycle. It adopts electric measure, stepless adjusting test speed, fast and effectively installing grips. It is provided with output to computer to realize extended function.

Main test items:

(1) Test bend torque;

(2) Test force;

(3) Speed of tested wheel;

(4) Accumulative test ileage;

(5) Accumulative test revolving number

Main structure:

(1) Load frame; (2) Computer control Unit; (3) Strong electricity control Unit; (4)Test Grips;

(1) Load Frame:

• It adopts floor welding structure design, conveniently install specimen, revolving drive power adopts excitation speed-adjusting motor to realize stepless adjusting speed. The surface, which installs specimen, is safely protected by safety cover.
• Bend loading approach adopts step motor driving. Load is measured by load cell.
• Centering mechanism on the bottom of main shaft realizes fast roughly centering.
• Jumping mechanism of main shaft measure precisely centering condition by displacement sensor, and check the bending condition of main shaft in testing process at the same time, to realize emergency stop function when wheel was destroyed by fatigue.

(2) Computer control Unit:

• Configured with industry control computer, A/D convert integrated card board inside computer completes signal amplifying and signal module converting.
• PComputer software is supported by WINDOWS, with the function of dynamic display, saving, output test report, etc.
  

(3) Strong electricity control Unit:

• Strong electricity controller completes to drive centering motor and control emergency stop.
