Endurance Testing Machine

ENKAY Cyclic/Static Rubber pad testing machines are state of the art machines based on Servo Controlled Closed Loop system. All the controls and data acquisition is through the computer. The system has a wave generator, cyclic & static, which forms a base to the compound signal. This signal is sent to PID controller. The machine response signal through base sensors that is displacement/load is also passed on to the PID controller. The difference in two signals actuates the torque motor of the servo valve thereby ensuring that the Endurance Testing Machine system follows the set path of the wave generator. Dwell time loading –unloading and recording of the reading is controlled through the software supplied as standard along with the system. Endurance Testing Machine is capable of conducting following tests on Elastomeric Pad and Silent Blocks.

Compressive Load Deflection Characteristic Test (As Per Clause 3.4.3 of RDSO Specifications)
Test Condition: - The system loads the pad from 0-20Tons three times at Strain rate of 10+5 mm/min. and then in the 4th cycle, it records Load versus Deformation Characteristics. Deflection characteristics are recorded and printed at Loads of 10, 15 and 20Tons.

Shear Load Deflection Test (As Per Clause 3.4.4 of RDSO Specifications)
Test Condition: - Refer to RDSO sketch No.WD2-7561-Ss/1, the system Loads the pad 3 times from 0-12Tonnes with the Strain rate of 10+ 5mm/min. and in the 4th cycle holds the load at 12Tonnes. Then Horizontal Load of 5Tonnes is given at a Strain rate of 10+ 5mm/min. 3 times successively and in the 4th cycle records Load versus Deflection characteristics.

Shear Fatigue Test (As Per Clause 3.4.6 of RDSO Specifications)
Test Condition: - Sample is fixed at 10 degrees to the horizontal as per Drawing No.WDX-91/7Alt.1 and then loaded from 7-22Tonnes at a frequency of 2Hz for 5,00,000cycles. The system automatically adjusts any permanent deformation and keeps the load within the specified limits of 7-22Tonnes.

Compression Test- Applying a Load of 15Tons for three successive cycles and record the deformation in the fourth cycle.

Torsion Test- The inner shaft of sample is clamped in the fixture and apply a rotating load on outer body for three successive cycles up to 8° and record the data at every 0.5° in the fourth cycle.

Endurance/Fatigue Test- Apply a load of 5Tons-15Tons at a maximum frequency of 1-2Hz with a maximum deflection of 3mm for 2,50,000 cycles or more.

The system is a highly advanced combination of hydraulic and pneumatic technology where σ1 is applied through hydraulic system in dynamic tests and σ2 & σ3 are applied through pneumatic system. It is totally based on Close Loop principle. The processing of the pre-programmed signal and machine response signal in the P.I.D. Controller is at the speed of 10 KHz. This keeps the machine working within the limits of + 1% of the programmed signal. Confining pressure & Back pressure are also controlled through computer and operates on close loop control mechanism.

The system is capable of performing following tests as per relevant standard ASTM/BS/AASHTO/IS etc.: Saturation, consolidation, UU, CU, CUBar, CD Triaxial tests with pore pressure and Volume change measurement, Isotropic and Anisotropic tests, Stress & Strain Path control tests, Liquefaction test, Stress Controlled Cyclic Triaxial strength of soils, Strain Controlled Cyclic Triaxial strength of soils, determination of modulus and damping properties of soils, Resilient Modulus of soils etc. (Optional- Ko consolidation tests & Bender Element tests)

Salient Features:
  • Based on Servo Controlled Hydraulic Closed Loop Feedback mechanism
  • Conforming to stringent requirement as per the International norms (ASTM 3999 & ASTM 5311)
  • Fully Computer Controlled operation to control Axial Loading, Cell Pressure & Back pressure with User friendly Software
  • Stress / Strain Controlled Cycling from 0.01 Hz to 10 Hz with 64 data sets per second
