ALIGNMENT FIXTURES Some applications require very precise specimen alignment. This is achieved using special fixtures designed to optimize specimen alignment.
Principle of Operation A variety of fixtures can be used to control both concentricity and angularity. The AlignPro™ system consists of a fixture that is mounted between the load cell and the load frame that allows easy adjustment of both concentricity and angularity. The fixture has been designed for use with a strain-gauged specimen mounted in the grips. The output from the gauges indicates the degree of misalignment, and these can be input to AlignPro software that provides a numerical and pictorial view of the degree of bending in the specimen. Adjustments can be made in real time, and the effect on bending seen immediately. This greatly simplifies and speeds the process of achieving optimum alignment.
Application Range • Static, fatigue and through-zero tests on materials where optimum alignment is critical 1
