Introduction of test methods for mechanical properties such as automobile frame and triangle arm

Auto parts triangle arm multi-channel mechanical loading test system is mainly used in automotive frame, cab, triangle arm, control arm, balance bar, shock absorber and other mechanical properties of the test study
.

The main uses include: completing the low-week repeated loading of the tested parts, loading, unloading and other routine tests
.

This series of products has the characteristics
of wide output force range, high control accuracy, easy to use and high reliability.

The test system can not only carry out low-cycle fatigue test, program control fatigue test, but also static constant rate, constant strain, constant stress control test and various conventional mechanical property tests, as well as fracture mechanics tests, natural force simulation tests, such as earthquakes, wind and waves, etc
.

According to the needs, part of the working condition simulation can also be carried out, so it has the advantages that any other kind of testing machine cannot match; In terms of practical testing, we have a large tonnage actuator designed for structural testing, the actuator form has a single rod and a double outlet rod two structural forms, the output force ranges from 100kN to 10000kN, the stroke can be determined according to the actual needs of the user, the actuator standard stroke is 200--500mm (± 100mm/±250mm), according to the structural test requirements can be configured with different specifications of the actuator, widely used in vehicle frames, composite structural parts material static mechanical performance test, including tensile , compression, three points and four point bending test, ; Fatigue tests of structural parts such as long balance bars, rotary arms, spline shafts, etc
.
can also be carried out.

From simple static structure tests to high-sized Lupp simulation tests, from single-channel tests to large component test room configurations, from vehicle bodies to three-axle rubber sleeve tests, this series of equipment can provide you with great help in validating new concepts, developing newer, more efficient and more economical civil materials and structures
