Crankshaft Connecting Rod Torsion Testing Machine
Category：Torsion Testing Machine
Introduction
The Crankshaft Connecting Rod Torsion Testing Machine adopts computer automatic control and an imported servo motor for loading. Specimens are installed and connected through corresponding fixtures. Within the allowable torque range of the testing machine, it can perform static torsion tests on various shaft components, automotive rear axles, structural components, and various material specimens.
Application
The Crankshaft Connecting Rod Torsion Testing Machine can be used for static torsion testing of:
(1) Crankshaft connecting rods
(2) Various shaft components
(3) Automotive rear axles
(4) Structural components
(5) Various material specimens
Software Functions
(1) Windows-Based Chinese Test Software – Supports test data acquisition and processing.
(2) Real-Time Data Processing – Test data can be collected, calculated, processed, displayed, and test reports can be printed in real time.
(3) Curve Traversal – Individual curve data points can be accessed with the mouse to obtain various test data. The torque-torsion angle curve can show the torque-angle relationship at any point. Local sections of the curve can also be enlarged and restored.
(4) Manual or Automatic Zeroing – The torque and angle measurement channels can be manually or automatically zeroed as required.
(5) Automatic Data Storage – Test conditions and test data are automatically stored and can be recalled when needed.
(6) Batch Testing – After test conditions are set, a batch of specimens can be tested successively. Test conditions, specimen parameters, test data, and results can be stored and recalled without resetting the conditions for subsequent tests.
