Model PQ-6 Pure Bending Fatigue Testing Machine


Features & Applications

This kind of machine is suitable to test the fatigue strength of metals or other materials. It is designed and manufactured fully according to the current standard GB4337-84 “method for rotary bending fatigue tests of metallic materials” and Standard ZBN71006-87 “Technical conditions of pure bending fatigue testers”. The testing machine is usually used to test the bending fatigue limitδ-1 of metals under the action of symmetrical repeatedly alternating bending force. Accordingly the tension-compression fatigue limit δ-1p  and torsion fatigue limitτ-1 can be determined by calculation according to experienced formula. The system has simple structure, easy to operate, stable & liable. It is very popular at factories and high school laboratories.
