DRIVE LINE AND SHAFT LINE ENGINEERING   More than 10 years' know how Models derived from aeronautics Experienced and validated simulation tools Advanced calculations of vibration and torsion and crankshaft stresses Critical frequencies determination Shaft line dimensions Bearings lifetime   DYNAMIC AND STATIC STUDIES D2T carries out studies and surveys on shaft lines. They claim a unique know-how in vibration and bearings modelling. Methodology implements software tools, designed by D2T, developed for aircraft and aerospace industries, for bearings studies. Bearings expertise The choice of bearings is major for lifetime of a rotating driveline and to lower power losses. Vibration analysis For all rotating drive lines, a vibration analysis needs to be carried out in order to guarantee that the modal frequencies are not excitable in the operating speed range. D2T carries out both flexion and torsional studies of drive line. Many examples are quoted in the datasheet.
