1. Definition of simply supported beam testing machine
The simply supported beam testing machine is a device specially used to test the mechanical properties of materials in the simply supported beam state. A simply supported beam refers to a beam structure supported at both ends and loaded in the middle. This structure is very common in engineering. The testing machine evaluates the performance of materials by applying concentrated or distributed loads and measuring data such as beam deflection, strain, and failure load.
2. Working principle of simply supported beam testing machine
The working principle of the simply supported beam testing machine mainly includes the following steps:
1.Specimen installation: Place the material sample to be tested on the support base of the testing machine, ensuring that both ends are fixed.
2.Load application: Vertical loads are applied through hydraulic or mechanical systems to simulate stress conditions in actual engineering.
3.Data collection: Collect the deflection, strain and load data of the specimen in real time through the sensor.
4.data analysis: Input the collected data into the computer system to generate stress-strain curves and other mechanical performance indicators.
