Servo Hydraulic Testing Machine for Fracture Toughness Testing with High Precision Data Measurement and Control System
Summary:
1. Main Machine Structure
The load frame of the Fracture Toughness Tester (Hydraulic Universal Testing Machine, UTM) consists of two columns, two guide rails, and an integrated hydraulic cylinder. The tension testing space is located at the upper section of the main machine, while the compression and bending testing spaces are positioned between the lower crosshead and the worktable—ensuring rational space allocation for diverse test scenarios.
2. Data Measurement & Control System
Equipped with a high-precision A/D converter module, the system performs real-time acquisition of force, displacement, and deformation data. It boasts exceptional measurement accuracy and reliable operational performance, fully complying with GB, ISO, ASTM, and other international/national standards for tensile, compression, bending, and shear tests of metal materials.
3. Transmission System
The lower crosshead is driven by a motor via a reducer, chain transmission mechanism, and lead screw assembly—enabling precise and smooth position adjustment of the testing space. This design ensures stable load transmission and accurate control of test processes, adapting to the size requirements of different test samples.
Standards:
ISO 6934 BS4449, ASTM C39, ASTM A370, ASTM E4, ASTM E8, ASTME9, ASTMA615, ISO6892, ISO7438, ISO7500-1, ISO 15630 EN10002-4, GB/T228-2002, GB 16491-2008, HGT3844-2008 QBT 11130-1991, HGT 3849- 2008,GB6349-1986, ASTM C165, EN826, EN1606, EN1607, EN12430 etc.
Principle:
Hydraulic oil stored in the oil tank is delivered into the hydraulic circuit by a motor-driven high-pressure pump. It subsequently passes through the high-pressure filter, differential valve group, and servo valve before entering the hydraulic cylinder.
The computer transmits precise control signals to the servo valve, regulating its opening degree and flow direction. This controls the oil flow rate entering the hydraulic cylinder, thereby realizing accurate control of test modes such as constant test force rate and constant displacement rate.
