Spring Pulling Fatigue Testing Machine

The spring pull fatigue testing machine is mainly used for dynamic performance, fatigue life and other mechanical performance tests of various structural components and parts. Consulting measurement and control, your wise choice!

　　Spring Pulling Fatigue Testing MachineMainly used for dynamic performance, fatigue life and other mechanical performance tests of various structural components and parts. Widely applicable to research institutes, metallurgical construction, national defense and civil defense, colleges and universities, mechanical manufacturing, transportation and other industries, it is an ideal and cost-effective dynamic fatigue testing equipment.

The previous hydraulic servo method had various problems such as high power consumption, waste oil treatment, noise pollution, vibration, etc. It can perform dynamic high and low cycle fatigue tests, program controlled fatigue tests, static constant rate, constant strain, constant stress controlled tests, and various conventional mechanical performance tests. It can also perform fracture mechanics tests, partial vibration and impact tests as needed, and can also perform fatigue life, crack propagation, fracture toughness performance tests, safety evaluation of actual specimens, and working condition simulations of materials or components in a broad range. Therefore, it has advantages that cannot be compared to any other type of testing machine and is the most highly recommended material testing equipment in the fatigue industry.
