Can XLRotor perform a torsional analysis?
Yes. Version 3 of XLRotor can compute damped or undamped torsional natural frequencies and mode shapes. You can also compute linear response to any harmonic(s) of shaft speed. In the transient part of the program you can compute torsional response to just about anything. Complete machine startups, electrical faults, gear backlash, nonlinear elastomeric couplings, synchronous motor torque pulsations, VSD excitations, etc.
