Automotive Rotary Knob Torsion Testing Machine

The Automotive Rotary Knob Torsion Testing Machine is mainly used for torsion testing of automotive volume control knobs, air-conditioning adjustment knobs, fan-speed adjustment knobs, headlight switch knobs, and other automotive components.

The tested specimen is installed between fixtures with adjustable spacing, allowing the machine to accommodate torsional mechanical performance testing of different specimens.

Application

The Automotive Rotary Knob Torsion Testing Machine is mainly used for:

(1) Automotive volume control knob testing

(2) Air-conditioning adjustment knob testing

(3) Fan-speed adjustment knob testing

(4) Headlight switch knob testing

(5) Automotive rotary switch testing

(6) Other automotive component torsion testing

(7) Torsional performance testing of materials or components

Test Functions

The machine can perform the following tests:

(1) Torsion angle testing of materials or components

(2) Torque testing of materials or components

(3) Curve analysis of materials or components

(4) Torsion time and speed testing

(5) Maximum torque and peak torque testing

(6) Specified-cycle testing

(7) Constant-torque testing

(8) Destructive testing

(9) Qualification testing

Software Functions

The test software displays the specimen's torque T, torsion angle θ, and test speed V. The torsion angle can be set for multi-point testing of torque and corresponding angle. The specimen can generally be twisted to fracture to determine one or more torsional mechanical properties.

(1) Windows-Based Chinese Test Software – Provides test data acquisition and processing.

(2) Real-Time Data Processing – Test data can be collected, calculated, processed, displayed, and printed in real time.

(3) Curve Traversal – Individual curve data points can be accessed with the mouse to obtain different test data. The torque-angle curve can show the relationship between torque and angle at any point, while local curve areas can be enlarged and restored.

(4) Manual or Automatic Zeroing – The torque and angle measurement channels can be manually or automatically zeroed when required.

(5) Automatic Data Storage – Test conditions and test data are automatically stored and can be retrieved 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 setting the conditions again.

(7) Test Report Printing – Detailed test reports can be printed.
