Detailed explanation of electromagnetic fatigue testing machine

1. Core principle: Electromagnetic resonance

Electromagnetic fatigue testing machine, also commonly known as "high-frequency fatigue testing machine" or "resonant fatigue testing machine". Its core working principle is the "resonance" principle of physics.

System composition: It mainly consists of the host frame, electromagnetic exciter, mass block, spring (usually the elasticity of the frame itself), control system, and measurement system.

Working principle: The system is designed as a "mass spring" resonant system. The controller drives the electromagnetic exciter to apply a small periodic force equal to the natural frequency of the system. At this resonance frequency, a small excitation force can generate a significant alternating load on the sample. It's like gently and rhythmically pushing a swinging swing, where every small force can make the swing swing swing very high.

Working frequency: usually between 30-300 Hz, much higher than traditional hydraulic servo fatigue testing machines (usually below 100 Hz).

2. Main features

Ultra high efficiency: Thanks to its high-frequency testing capability, the time required to complete fatigue tests of hundreds of thousands or even billions of cycles is extremely short, making it very suitable for high cycle fatigue testing.

Energy saving and environmental protection: In resonance state, the main energy of the system is used to overcome damping and internal energy consumption of the sample, and only a small amount of external energy needs to be supplemented to maintain vibration, resulting in extremely low energy consumption and quiet operation.

Load range: The dynamic force range is wide, ranging from a few newtons to several hundred kilonewtons.

3. Main application areas

Materials research: High cycle fatigue performance (S-N curve) testing of metals, composite materials, and other materials.

Component testing: automotive engine components (connecting rods, crankshafts, valves, etc.), aviation fasteners, bone implants, springs, blades, and other components that require durability verification.

Quality control and comparative testing: sampling durability inspection on the production line, or comparison of fatigue performance of different processes and batches of materials.
