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.
