Technical analysis of high frequency connecting rod fatigue testing machine

1.Core functions

High frequency dynamic test: Support 20-300Hz high frequency cycle load, simulate extreme engine conditions

Precision load control: maximum dynamic load up to ±200kN, static load up to ±300kN, to meet the needs of heavy engine connecting rod test.

Multi-axis test capability: support tensile, compression, bending composite load, accurately reproduce the actual stress state of the connecting rod.

 2.Material and process optimization

The use of forged steel/powder metallurgy custom materials, Cincinnati machining center multi-axis linkage heat treatment, hardness radius control accuracy, tensile strength of more than 900MPa; Shimada cleaning line achieves zero residue degreasing to ensure coating strength. Meet the needs of high level diesel engines such as Cummins,John Deere,Perkins.

3.Technical advantages

Closed-loop servo hydraulic system: ensure high response speed and load stability, waveform distortion rate < 1%.

Intelligent data acquisition: Integrated strain gauges, displacement sensors and temperature monitoring to analyze crack initiation and growth trends in real time.

Environmental simulation module: Optional high temperature (above 200℃) or corrosion environment chamber to verify the durability limit of materials.

 4.Application value

Shorten the development cycle: Quickly screen for design defects with accelerated Life testing (ALT).

Reduce warranty risk: Ensure connecting rods meet international fatigue standards such as ISO 12106 and ASTM E466.
