Experimental Modal Analysis on 880MW Generator

To better understand any Structural Vibration behaviour, the resonant frequencies of a structure need to be identified and quantified. One of the Engineering methods to determine the structure response is Experimental Modal Analysis. In every development of a new or modifying the existing mechanical product, structural dynamics testing on product is preformed to assess its dynamic enactment.

GE Power (General Electric) is one of the largest designer, manufacturer and supplier of Power generation equipment.

One of their subsidiary plants in India have developed 880MW AC Generator that is to be qualified for its Eigenvalue performance.


Vibration Investigation on Drive Motors

Steel Plants comprise high power mechanical transfer systems that are used for large material transfers; the typical drive arrangement consist of a variable frequency driven AC Motor, mechanical fluid coupling, gear box and finally the drive belt rollers.

Paul Wurth (PW), Italy is a world renowned Blast furnace and other process industry related technology company. Of the many projects and installations that PW has commissioned world over, India also happens to be their prime business area and are involved with multiple large steel industries.


Evaluation of Structural behavior of Wind Turbine

Renewable energy electrical power generation is a fast growing Industry and many companies are investing in this business. Like in many parts or the world and in India, Karnataka also has many such installations where wind based electrical energy is being generated.

Since the Wind Turbines are exposed to elements of nature lot more directly than other formats of power generation, the wind tower in particular are subjected to high energy wind loads that affect the dynamic performance of the system as a whole. This combined with the characteristics of the Strata where the tower is installed, further influence the dynamic stability of the tower and the wind turbine as a whole through its operational life.



RCC Roof Cricket Pitch Noise Mitigation

The sport of Cricket is a Game but is more a religion in many countries; In India, Cricket happens to be the most revered game with millions of fan following and a good number of qualified stadiums to support the sport.

Most of practice pitches are made as an integral part of the main stadium; however, Karnataka State Cricket Association (KSCA) is planning for a high tech modern sheltered pitch to be constructed above the stadium building for use during rainy and other non-conducive seasons; the issues of Noise and Vibration created by the sport activity to the premises below the stadium terrace is investigated.
