A fatigue testing machine is a device to assess the fatigue life of materials. It produces cyclic loads that simulate the conditions of service and measures their effect on a specimen.
It checks the strength of the material under repeated loads and helps predict the final life span of equipment and machinery used in heavy industries like mining, engineering, etc.
Fatigue machine is also known as fatigue test machine, fatigue strength tester, or fatigue tester.

When we talk about the different types of fatigue testing machines, three types are the most common forms of this machine: Strain Control, Low Cycle Fatigue, and load control high cycle fatigue.
Strain control is a process of controlling the load on an object. It ensures the strain in a component does not exceed the specified value. It refers to controlling the strains within allowable limits and maintaining the controlled strains for long periods.
Low cycle fatigue involves applying stress of low levels on an object to reduce its fatigue strength. It is a type of fatigue that occurs due to the large plastic strains that occur before the failure under the load number of the load cycle.
Load control high cycle fatigue is when the load applied to an object is changed very quickly and frequently. High cycle fatigue is when a material breaks down due to repeated loading.
Apart from that, there are several other types of devices. Let us know more about it here.
A wheel disk-hub fatigue test machine is a piece of unique machinery that is valuable in carrying out the fatigue strength test of steel wheels.
It is a non-contact fatigue testing machine used to test the wheel disk hubs' fatigue life.
It examines the fatigue life and load capacity of wheel disk- hub under different loads, speeds, and temperature scope.
It carries out the wheel disk-hub fatigue test of vehicles under running conditions.
It is widely popular for examination and testing vehicle components such as shock absorbers, steering wheels, front wheels, etc.
A dynamic fatigue testing machine tests the dynamic load-carrying capacity of a component or assembly.
It is helpful to determine the strength of a piece exposed to repeated stress, such as impact and vibration. The test configuration and loading condition are necessary for the component's fatigue life.
Dynamic fatigue machines may be linear or rotary, depending on the applied dynamic load.
A rotating-beam fatigue testing machine facilitates testing of materials to generate the S-N curve from which one can determine endurance limit.
It uses beams to conduct stress tests and other types of mechanical testing. These beams rotate several times and attach shafts at opposing ends with a clamped workpiece placed in the center.
The rotating beam fatigue testing machine is a similar apparatus but serves a different purpose.
The beam or equivalent device turns until one end inevitably fails due to excessive vibration, stress, or other damaging force.
This technique is frequently employed when conducting tensile tests to determine materials strength or elastic limits.
A servohydraulic fatigue testing machine tests the strength of the material in a controlled environment.
It applies stress to certain parts of the specimen until it breaks and then measures the load at which it broke using some force transducer.
It helps test cyclic loads or static loads, and this data is valuable in calculating parameters such as ultimate load, yield point, or percent elongation.
These machines are popular to test various metallic and non-metallic materials while being put under pressure.
Tension, compression, flexural, and bending tests are all sample methods used to ensure proper quality control when the time comes to create or improve products.
A reciprocating fatigue testing machine helps determine the fatigue strength of high cycle fatigue, low cycle fatigue, or cyclic-tensile materials.
It can help test the toughness of metal parts and the fatigue life of metal and composite laminates, adhesive joints, and other materials subjected to cyclic stresses.
The RFT applies a repeated load using a controlled stroke length at a specified frequency. The device simulates the fatigue process. It helps determine the life expectancy of metal parts under repeated load.
Spring Fatigue Test Machines measure and determine the spring life and fatigue strength. The test results are practically helpful in assessing the quality and making maintenance decisions.
Spring Fatigue Test machines are primarily valuable in metallurgical industries, including high-performance springs found in cars, aircraft, industrial machinery, and testing equipment.
It is excellent and reliable equipment for the testing of spring materials. The fatiguing tests help determine the working life, maximum stress, and residual strength of springs. They are helpful for monotonic tension and compression-based mechanical tests.
Axial fatigue testing machine helps determine the fatigue strength of materials. In this test, the load that applies along the sample axis then compares results to similar samples subjected to various levels of cyclic loading (i.e., a known number of cycles).
It tests the durability and strength of machine parts like shafts, gears, etc., that have metal on metal contact.
It also tests the ability of a material to withstand repeated stress in the same plane.
Torsional fatigue testing machines are valuable in prompting real-life service requirements and checking product grade for products such as drill device bit tips and medical appliances, wire, screws and other fasteners, and much more.
It can avoid the influence of other factors on testing and obtain a more accurate result. The main feature is that it can test two sides of the same sample simultaneously by using a high-precision electric system and control system, which greatly shortens the time for loading and unloading samples and reduces labor intensity.
It performs a torsion test on a material sample after being subjected to a specified level of cyclic loading.
Radial fatigue testing is a non-destructive technology that effectively evaluates the material's mechanical properties under test.
Results are a reflection of the inner and outer structure and surface conditions. It is an electrically driven fatigue testing machine that simulates the load forces that a wheel experiences while cornering on the road.
It uses a horizontally moving carriage to create radial and tangential stress, replicating stresses during use.
A cyclic fatigue testing machine tests the durability of various materials. A material that fails in cyclic testing is unsuitable as an engineering material, as it will fall under repeated stress (repeated loading and unloading).
Cyclic fatigue machines are useful in performing fatigue testing on a product. It is valuable to produce many cycles, and it is usually helpful in combination with another type of mechanical testing equipment.
It tests the durability of machinery and materials based on their resistance to repeated loads.
