Application of BFA vertical small beam fatigue testing machine:

The BFA vertical small beam fatigue testing machine is used to test the fatigue life of asphalt mixtures under repeated bending loads.

Introduction:

• The Australian IPC BFA pneumatic vertical four point bending small beam fatigue testing machine mainly consists of a set of support mechanical system, which is equipped with pneumatic lateral positioning and clamping, and a digital servo controlled pneumatic actuator is built into its base.
• The Australian IPC BFA pneumatic vertical four point bending small beam fatigue testing machine has a small beam support system designed to apply a 4-point bending load to asphalt mixture small beams, and allows all loading and reaction points to self loadBy translation and rotation.
• The servo motor driven by ball screw is used for vertical clamping of the specimen. The motor continues to work during the testing process, tightening the slack formed on the clamping surface due to deformation of the specimen. The clamping force is controlled by adjusting the motor current. The power supply for the motor drive circuit is provided by IMACS.
• The Australian IPC BFA pneumatic vertical four point bending small beam fatigue testing machine includes a control and data acquisition system as well as testing software.

System features:

• Compact design, vertical testing system, no need for UTM series loading rack
• Digital servo control pneumatic actuator provides accurate loading waveform control
• The new 'floating straight edge' sample surface sensor reduces errors (including errors caused by the flexibility of the bracket)
• Sine or semi sine strain/stress control loading modes
• Electric specimen clamping with controllable force
• Pneumatic lateral fixture helps straighten the position of the small beam
