Fatigue testing system for all types of components, has compound test controller that operates based on software program to regulate operation of motor, frequency converter, and accelerometer which form coordinated loop-back system

The system includes a compound test controller for regulating the operation of a motor, a frequency converter, and accelerometer which form a coordinated loop-back system. The compound test controller operates based on a software program. The system also includes a data acquisition system is provided for obtaining gauge readings in real time. The system also includes an exciter for simulating a variable force in time. The exciter has two adaptable jaws that can be set in any position at the length of a specimen for testing. The motor drives the exciter. A pendulum is used for varying the simulation level of the exciter by addition or redeployment of weights within the exciter. A modifying unit is provided for changing specimen table distribution. Various adjustable weight sections are placed in the middle of the positioned jaws.
