Two flexible aluminum shafts modeled using a lumped parameter approach. Both shafts consist of 20 segments containing inertias, damping, and stiff torsional springs. At the start of the simulation, the clutch is unlocked and the driven shaft is free. Note that the initial velocity of the motor shaft is set to 200 rad/s and that the system starts at steady state. The clutch engages and disengages during the test, and during each event the effect of the shaft flexibility can be seen in the simulation results.

Two flexible shafts that have torsional and transverse flexibility. One shaft computes transverse motion using computed eigenmodes, and the other shaft uses a lumped parameter approach. The boundary conditions on the shafts can be changed on the block masks.

Basic operations of a torque converter including lock-up clutch mechanism. You can select three different simulation cases - Basic Lock-up, Drive Mode Test, and Coast Mode Test.
