WE TAXIED FROM TXWY R RAMP AROUND THE ENTIRE ARPT ON TXWY B AROUND RWY 36C BECAUSE OF DEPS OUT TO RWY 36L. THIS IS THE LONGEST TAXI RTE POSSIBLE AT EHAM ARPT. WE TOOK THE RWY (RWY 36L) AND CLRED FOR TKOF AS A CHK AIRMAN. I WAS DOING OPERATING EXPERIENCE WITH NEW HIRE STUDENT. I GAVE HIM THE ACFT AND COMPLETED CHKLIST. AS FO PUSHED UP THRUST LEVER; THERE WAS A MUFFLED BANG TYPE SOUND. SINCE WE HAD A 90 DEG XWIND FROM THE L; I FELT MAYBE WE HAD COMPRESSOR STALLED THE DOWNWIND ENG; BUT ALL PARAMETERS FOR ENGS NORMAL. ALSO; THE ACFT HAD ROLLED A SMALL AMOUNT AND FO WAS A LITTLE AGGRESSIVE ON BRAKES AND STOPPED ACFT ROLL. NO OTHER INDICATIONS SHOWED ABNORMAL SO WE STARTED TKOF ROLL. AT ABOUT 110 KTS ANOTHER BANG AND ACFT BEGAN VIBRATING VERY HVY. SINCE WE ALSO HAD A LOT OF BIRDS ON TKOF; I FELT WE HAD AN ENG PROB AND HAD TOOK IN BIRDS. THE ACFT SEEMED TO STOP ACCELERATING SO I TOOK OVER AND REJECTED TKOF. WE STOPPED ON RWY 36L.
