Composition of fatigue testing machine

The fatigue testing machine is characterized by high load, high frequency and low consumption, thereby shortening the test time and reducing the test cost. The fatigue testing machine is used to determine the fatigue characteristics, fatigue life, Pre-crack and crack growth test.

1. The composition of the fatigue testing machine

The fatigue testing machine is composed of the main machine, the high temperature furnace, the high temperature fixture, the high temperature deformation, and the measurement and control device. I believe that professionals know that because the high temperature creep and endurance test cycle is very long, compared with the short-term mechanical performance test, the creep The change and endurance experiment has stricter requirements on the load, temperature control, deformation measurement and control of the testing machine, and the long-term stability of the system, and the requirements for the experimental process are also very high. In a constant load and temperature environment, the tested samples The phenomenon of slow plastic deformation and fracture will follow the change of time. The creep test measures the amount of deformation that will change with time, and the endurance test measures the time to reach the fracture duration.

2. The daily basic management of the fatigue testing machine

1. Reasonable and effective management must be taken for the technical performance of this type of equipment, such as current and voltage, working environment temperature and humidity, equipment load and other related limit parameters, which need to be actively understood and paid more attention.

2. If the equipment adopts the handover working mode, then the corresponding handover system must be specified to ensure that the post personnel can accurately handover the operation status of the equipment during the handover process. When handing over, it is necessary to start with the operating conditions of the equipment, whether there are abnormal phenomena, and the detection and operation of materials.

3. The correct operation steps of the fatigue testing machine include the preparation work before the operation and the normal sequence of different materials during the operation.

4. For the basic safety issues of the fatigue testing machine in the use process, it is necessary to know that non-working technicians in this position cannot operate privately without the consent of the relevant leaders.

5. Insist on basic cleaning and maintenance for this type of equipment. When the equipment has a serious failure, it must be stopped, and the professional maintenance department must be notified to deal with it. The operation can not be restarted until the failure is eliminated.

6. Equipment maintenance is divided into monthly maintenance, quarterly maintenance and annual maintenance. Pay attention to the places where the equipment is easily damaged, and formulate corresponding inspection requirements for different structures.
