Developing an Engine Connecting Rod Fatigue Test System Based on CompactRIO

The Test System

"Using NI CompactRIO hardware and NI LabVIEW system design software to develop a reliable engine connecting rod tensile and compressive fatigue test rig."

- Hongrui Liu , Automobile Engineering Research Institute, Department of Energy Engineering, Zhejiang University

The Challenge:
Developing a test rig that determines loading force and frequency according to engine and connecting rod parameters; controls the hydraulic system according to the predefined load force and frequency; monitors test status in real time; captures connecting rod failures; and acquires, stores, and analyzes data.

The Solution:
Using NI CompactRIO hardware and NI LabVIEW system design software to develop a reliable engine connecting rod tensile and compressive fatigue test rig.
