BMT-D/SA – SHOCK ABSORBER TESTING MACHINE

The machine is a 25 kN Servo-Hydraulic Shock Absorber Test System, designed specifically for dynamic testing of automotive components—mainly friction tests, sliding tests, and life-cycle tests—according to TS 3032 standards.

System consists of:

  • Double-acting servo-hydraulic actuator with force capacity up to 25 kN Dynamic Load, resistant to at least 1 G acceleration
  • High-stiffness, precision-aligned load frame with 4 columns and actuator in upper crosshead.
  • 150 mm (±75 mm) of usable stroke
  • The test system can perform dynamic applications up to 2 Hz with a speed limit of 1000 mm/s.
  • Frequency and amplitude can be adjusted within the speed limits. The system is capable of performing
  • Non-stop tests up to 2,000,000 cycles.
  • Designed for both dynamic and static testing on a variety of materials and components
  • Machine is suitable for TS 3032 Standards for 3 types of test scenarios: Friction test of gas, Sliding test, Life test.
  • Frame has a 5 test stations to test 5 samples at the same time.
  • Adjustable upper crosshead with hydraulic lifts and locks fitted as standard for easy adjustment of daylight
  • Advanced load cell for faster testing and reduction of inertial errors
  • Low friction actuators for higher side-load resistance or material critical applications
  • Compatible with a large range of grips, fixtures, chambers, video extensometers, protective shields, and other accessories
  • Hydraulic control unit equipped with a servo valve controlled, water cooled heat exchanger system and connected to the Chiller unit to be supplied with the system;
  • High dynamic servo valve.
  • The MTS consists of a contactless electromagnetic displacement sensor with 0.001 mm resolution.
  • Servo closed-loop controlled electronic control unit
  • Appropriate dynamic testing software Fatigue rated load cell
  • Load measurement and control is carried out with a 25 kN capacity fatigue rated load cell between 2% and 100% of the device capacity with class 1 or better sensitivity according to ISO 7500-1 standard.
  • Displacement measurement and control It can be performed with an accuracy of 0.01mm with an SSI type sensor with non

 

 

SOFTWARE AND CONTROLLER

The BESMAK Servo-hydraulic Dynamic Test System is supplied with a digital EDC controller that provides full system control including features such as automatic loop tuning, amplitude control, specimen protect, 24bit resolution across the full range of transducers, and adaptive control technology. It also allows access to Besmak Universal™ Dynamic Testing software for dynamic tests, static tests, and other applications. Digital EDC controller has a data acquisition speed of 10 kHz.

 

REMOTE CONTROL UNIT

With the help of Remote Control Unit user can perform test, can control speed of actuator for sample adjustment, grips control, load / deformation / displacement and strain values display in real time, adjust and control ovement / positioning of grips, assign max.-min. limit etc. The most important feature provided by Remote Control console unit is the user does not have difficulty when placing the specimen on the grips because of the flexibility / mobility of device. In an emergency case, test can be stopped immediately by pushing the emergency button on the Remote Control console.

 

HYDRAULIC UNIT

System comes with advanced hydraulic Power Unit with hydraulic pump driven by electrical motor, smooth and high flow rate (70 liter/min) , with manifold and pressure limit and actuator safety valve, oil tank , comes with necessary joints and hose. Hydraulic power unit is equipped with high response and servo valve. Hydraulic power unit also equipped with heat exchanger(Chiller Unit). The system is suitable for operation with 3 phase 380 V, 50 Hz.
