Question 3 A WT is a complex machine comprised of multiple mechanical and electrical subsystems, including the main bearing, blades, gear box, and generator, among others. The main bearing is a key subsystem that assists the conversion of wind kinetic energy into mechanical energy. The reliability of the main bearing degrades over time due to wear out of its rolling bolts, and cracks of inner and outer rings races resulted from ball rotations and vibrations. The field data shows that the hazard rate function of the main bearing can be modelled as h (t) = 0.002 failures/year. Estimate (a) Cumulative hazard function. (b) Reliability function (c) Mean Time to Failure (MTTF)
