Due to the particularity of the test object and the high requirements of the test, the connecting rod torsion testing machine has the following characteristics:

1. special fixture

• This is the most crucial part. The fixture needs to accurately simulate the installation state of the connecting rod in the engine.

• Large end fixtureUsually designed to accommodate and fix the connecting rod big end bearing cover, and connected to the crankshaft pin simulation shaft.

• Small end fixtureFixed connecting rod small end, usually connected to the simulated shaft of the piston pin.

• The fixture must ensureHigh centering accuracyTo prevent additional bending moments and ensure that the torque is applied purely to the connecting rod body.

2. High performance actuators and drive systems

• Adopting high-power and high dynamic responseservo motororServo hydraulic systemIt can generate high-frequency and high-precision alternating torque.

• For fatigue testing, the dynamic response frequency and stability of the equipment are crucial.

3. High precision measurement system

• torque sensorReal time and accurate measurement of applied torque.

• angle encoderMeasure the torsional deformation angle of the connecting rod.

• Dynamic strain gaugeUsually, strain gauges are pasted in the stress concentration area of the connecting rod (such as the transition of the rod body and around the bolt hole) to directly measure local strain and provide key data for fatigue analysis.

4. *Control System and Software

• closed-loop controlCapable of precise control of torque, angle, or strain.

• Test sequence programmingComplex test waveforms (sine wave, triangular wave, square wave, etc.), amplitudes, frequencies, and cycle times can be set.

• security monitoringSet upper and lower limits for torque, angle, or number of cycles. Once the sample breaks or reaches the set value, it will automatically shut down.

• Data Collection and AnalysisAutomatically record the torque angle curve and cycle times of the entire testing process, and generate the fatigue S-N curve (stress life curve).

5. Security protection system

• A sturdy protective cover must be equipped to prevent fragments from flying out of the connecting rod in case of fatigue fracture, ensuring the safety of the operator.
