Function
The High and Low Temperature Torsional Fatigue Testing Machine consists of a high and low temperature chamber, temperature control system, servo power system, precision transmission system, and computer control and display system.
It is suitable for durability and fatigue life testing of various torsional elastomers, torsion springs, metal materials, non-metal materials, and other specimens under high and low temperature environments.The testing machine uses a servo speed control system to control motor operation. The computer sends commands to control the motor’s forward and reverse rotation, completing the reciprocating torsional fatigue test of specimens.
