YJW-5000 Microcomputer Control Electro - Hydraulic Servo Shear
- The YJW-5000 series of microchip controlled electro-hydraulic servo
shear testing machine is mainly designed for tests on pot bearings,
disc bearings and spherical bearings to inspect their mechanics
performances. This product is capable of bulk modulus tests, shear
modulus tests, shear angle tests, ultimate compressive strength,
friction modulus tests, rotation tests, and measuring axial
compressive deformation and lateral deformation in load tests on
pot bearings. It is also capable of compression tests on jack and
other big components.
- This product presents an ideal choice for rail, bridge construction
related fields, bridge rubber bearing manufacturers, traffic
engineering quality control department, civil construction quality
control department and etc.
- This product is integrated with a multi-channel coordinative
digital load control system, enabling controlling methods including
constant deformation speed, constant loading speed and etc.,
meanwhile switches smoothly in between. . The system retrieves
testing data automatically, and then processes the data under
regulations and standards. It takes no human resources to read
deformation data, requiring only one operator to perform the whole
test. Assistance is required to install specimen or perform
rotation tests. The measuring and controlling unit is developed by
our own engineers, integrated with the leading high-performance
AEC-1000 Controller, which is usually equipped on high-end material
testing machines, and the pioneered modular Test Live computer
testing software ensuring the reliability and precision of the
system. After years of application and refinement, our system
features matured technologies, reliable operations and powerful
functionalities. The test data of load, displacement and
deformation are automatically retrieved, processed and stored
meanwhile displaying real-time testing curves. Test reports can be
printed under related standards.
- This product adopts a four-column structure as its main frame,
featuring a stable, high-stiffness structure, as well as long-term
stability, convenient operations, reliability and safety.
- This product can also apply the top-mounted cylinder structure to
perform tests on shock isolation rubber bearings.
- This type complies with the standards and requirements of GB/T
2611-2007, JT/T 4-2004, GB/T 17955-2009, JT/T 663-2006, JT/T
391-2009, GB 20688.4-2007.
- The hydraulic system features a quick withdraw unit to promote
- Electromechanically adjustable test space between upper and lower
compression platen. Horizontal shear components are moveable
electromechanically and easy to operate.
- Multi-channel coordinative digital load control system makes it
more convenient to perform tests.
- A wide range of test projects are supported by the testing software
(14 categories), perfect support for the latest mechanics
performance testing standards on rubber bearing products.
- Support for management permissions for various user types
(Operator, administrator and engineer).
- Easy to set testing methods. Administrators may configure in a
specific range of settings under related standards, pre-installed
with two sets of testing schemas (standard testing schema and
custom testing schema).
- Highly automatic testing process. Capable of general
functionalities including automatically aligning with zero, smooth
continuous loading and un-loading, automatic sustaining. Capable of
monitoring the whole testing process, automatic testing data
measuring and processing, automatic testing curve displaying,
automatic saving the source data and curves of tests.
- Highly user-friendly testing process. Operators may perform testing
procedures according to system suggestions. Other interactions may
retrieve testing state suggestions in time.
- The testing software supports displaying various categories of
testing data, and drawing real-time common-type curves including
load-time, displacement-time, deformation-time, load-displacement,
load-strain, stress-strain and etc., as well as partial curve
- Testing data automatic processing, one-click data calculation,
automatic testing report obtaining and printing.
- Integrated with a complete set of templates for shear tests from
the Ministry of Transport of the People’s Republic of China.
Customizations are also supported to cater for users’ specific
- The testing software is integrated with a complete and safe data
storing system. Supports tracing history testing data, automatic
test report generating and printing.
- Rich and detailed help documentation installed in the test
software. Contents including testing descriptions, operating
procedures, cautions can be viewed or printed through the help
- Integrated with travel limit protection and full scale overload
