Hydraulic Universal Testing Machine
Advanced testing equipment featuring unique lead screw clearance elimination mechanism for enhanced testing accuracy and reliability.
Purpose and Applications
This hydraulic universal testing machine performs comprehensive material testing including tensile, compression, bending, and shear tests for both metallic and non-metallic materials. The system supports specialized testing scenarios such as brick flexural and compression testing, as well as tensile, compression and bending testing for steel reinforcing bars.
Advanced control capabilities include constant-rate loading, constant-rate deformation, and constant-rate displacement testing with seamless transitions between force control, deformation control, and displacement control modes within a single testing cycle.
Widely utilized in aerospace material testing, engineering quality inspection, academic research institutions, and industrial quality management. All testing procedures and data processing strictly comply with GB228.1-2010 (Metallic materials - Tensile testing at ambient temperature) and comprehensive GB/ISO testing specifications.
