The loading system is a crucial component in mechanical testing, primarily used to apply compressive, tensile, or bending forces to concrete specimens. For example, a compression testing machine typically consists of hydraulic cylinders, a pressure pump, and a loading frame, simulating the stress state of concrete in actual engineering projects through stable force application. The stability of the loading system directly determines the accuracy of the test results.
The measurement and sensing system is used to acquire real-time deformation and stress data of the specimen. Common components include pressure sensors, displacement sensors, and strain gauges, which convert physical changes into electrical signals and transmit them to the control system for processing, thereby obtaining accurate mechanical parameters.
The control and data processing system is mainly responsible for the automatic control and data recording of the testing process. Modern concrete testing instruments typically employ microcomputer control systems, enabling loading rate adjustment, automatic failure detection, and test data analysis and storage, improving the standardization and efficiency of testing.
The frame and auxiliary structures include the load-bearing frame, protective devices, and specimen clamps. This structure ensures the overall rigidity and safety of the instrument while facilitating the installation and fixation of specimens of different sizes, making the testing process more stable and reliable.
