(20 min.) Torsional analysis process of 2- stage planetary wind gearbox and its stiffening

Parthasarathy Ravichandran, Mechanical Design Engineer, Suzlon Energy Australia


It is brief description on process of  torsional analysis of complete drivetrain, where focus is in 2 stage 1 helical wind gearbox simulation is carried out. The simulation is performed as per rotor loads as well as testbench case. You will learn how design evolves for gear housing design and behaviours of natural frequency when stiffening process is carried out to keep the gearbox stationary parts away from resonance frequency by rotating shafts.
