This article will introduce in detail the definition, working principle, application fields and recent hot topics of the hydraulic universal strength testing machine.
1. Definition of hydraulic universal strength testing machine
The hydraulic universal strength testing machine is a device driven by a hydraulic system and combined with an electronic control system to achieve multi-dimensional testing of the mechanical properties of materials. It mainly consists of hydraulic system, loading frame, sensors, control system and data acquisition system. The equipment can simulate the stress conditions of materials in actual use and provide a scientific basis for material performance evaluation.
2. Working principle of hydraulic universal strength testing machine
The working principle of the hydraulic universal strength testing machine is to send hydraulic oil into the cylinder through a hydraulic pump, pushing the piston to move, thereby exerting force on the sample. The control system achieves precise control of the loading speed by adjusting the flow and pressure of hydraulic oil. The sensor monitors force and displacement in real time, and the data acquisition system records and analyzes the test results.
