Principle analysis of hydraulic servo fatigue testing machine

1、 Working principle

2、 Main components

The hydraulic servo fatigue testing machine mainly consists of the following parts:

1. Hydraulic system: used to generate test loads and control and adjust the loads during the test process.

2. Test bench: used to support the test piece, as well as to fix and clamp the test piece.

3. Loading system: composed of inertial mass, load arm, and loading motor, used for reciprocating loading of the test piece.

4. Control system: used to achieve automatic control, data acquisition, and processing of experiments.

3、 Application scenarios

Hydraulic servo fatigue testing machines are widely used in the field of materials science, especially in the areas of metal materials, plastic materials, rubber materials, composite materials, etc. They can be used to test the fatigue life, fatigue crack propagation performance, fatigue strength, fracture toughness, and fatigue failure mechanism of materials.
