Test Facilities


Wind turbine test facility

W&M group in collaboration with government agencies support (JTC and MPA) have developed a wind turbine test site at south of TUAS in Singapore for testing and deploying of turbines less than 15m height to test scaled turbine along with micro-grid integration. This helps to test various turbine innovations in field conditions. This testbed centre can cater for deploying/testing multiple rotor configurations of wind turbines of up to 6m diameter. Currently, the team has an MOU with JTC for next 3 years.


Materials’ characterization and testing facility

Mechanical testing 

The W&M team carries out mechanical testing of materials both at coupon (according to ISO standards) and component (by mimicking the real time load conditions) levels. The mechanical testing lab is equipped with two fatigue testing machines: axial and rotating bending. The uniaxial fatigue machine used is Shimadzu Servopulser which can be operated in a frequency range of 0.5 – 30 Hz with a load cell of about 50 kN and accuracy of ± 0.5%. The FTM 200 is a rotating bending fatigue test machine that can operate at a frequency of 70 Hz for accelerated testing. The Maximum bending stress that can be applied in the machine 200 Kg/cm3 and accuracy of about ± 1%. For studying the wear and friction characteristics of materials pin and ball-on-disk tribometers are used. While the pin is static in pin-on-disk tribometer enabling to simulate real life conditions of practical wear situations at different contact pressures, the ball in ball-on-disk rotates independent of the disk enabling to simulate the characteristic of slip between metal pairs while in contact.

Gear test rig 

The W&M team has incorporated a FZG gear test rig which simulates the accelerated scuffing in the test gear samples. This machine operates at a constant speed of 1450 rpm for a fixed period (21700 revolutions, i.e. approximately 15 min) by successive increasing of loads until the failure criteria is reached. The test gears are examined initially and after the prescribed duration at each load stage for cumulative damage (scuffing) to the gear tooth flanks.

Materials’ characterization 

W&M team utilizes ERI@N’s materials characterization facility equipped with advanced characterization instruments as listed below for pre and failure analysis of materials using:

a)    JEOL JSM–7600F state-of-the-art thermal field emission scanning electron microscope

b)    Bruker D8 Advance X-ray diffractometer with an accuracy of ± 0.005o

c)    Alpha-step IQ stylus-based surface profiler

d)    Quantachrome NOVA 3200 BET surface area and pore size analyser and

e)    Asylum research MFP3D atomic force microscope (AFM).
