Precision Assurance of Tensile Testing Machine

 

Equipment Selection and Calibration

 

Select High - Precision Equipment: When purchasing a tensile testing machine, it's necessary to choose equipment with good precision and reliability. Usually, the force - value precision of a high - quality tensile testing machine can reach within ±0.5% of the full scale, and the displacement precision can reach ±0.001mm. For example, some well - known brand electronic universal tensile testing machines adopt high - precision load sensors and displacement sensors, which can meet the high - precision requirements of the yield - strength test of ship - plate steel.

 

Regular Calibration: Tensile testing machines need to be calibrated regularly, and the calibration cycle is generally one year. The calibration process requires the use of standard weights or force - value calibration devices to check and adjust the force - value measurement system of the testing machine. For the displacement - measurement part, high - precision measuring tools can be used to calibrate the displacement precision of the extensometer. The calibration work should be carried out by professional metrology institutions or technicians of the equipment manufacturers to ensure that the force - value and displacement - measurement precision of the equipment meet the standard requirements.

Control the Precision of Tensile Speed

 

Speed - Control Principle: The tensile testing machine controls the tensile speed through the motor and transmission system. To ensure precision, the testing machine usually adopts a closed - loop control system, which can monitor and adjust the tensile speed in real - time. During the test of ship - plate steel, the precision requirement of the tensile speed is relatively high, because the change of speed may affect the stress - strain curve of the material, and then affect the measurement result of the yield strength.

 

Speed - Precision Requirement: According to relevant standards (such as GB/T 228.1 - 2010), for the tensile test of metal materials such as ship - plate steel, the tensile speed should be controlled within the specified range. For example, for the tensile speed in the yield stage, it's generally required to be between 0.00025 - 0.0025/s (strain rate) to ensure the accuracy and repeatability of the test results.
