ARLA^®-SIMUL

supports ARLA's Engineering Services for Drive Systems

ARLA®-SIMUL is a powerful PC based software which is used by ARLA for engineering purposes to simulate torsional vibrations in drive systems in the time-domain. It is rather important that total drive systems (motor, couplings, gears and any load effects) can be taken into account. The simulation software supports R&D activities (such as prototyping, optimization) and also the machine and failure diagnosis.

One of the main features of ARLA®-SIMUL is the solution of nonlinear and/or non-steady-state processes. Examples: gear backlash (e.g. to minimize rattle noise in manual car transmissions), high-flexible couplings, slip effects, time-dependent shift operations, friction effects, etc.

ARLA offers a professional customer service: ARLA^® Engineering. This implies the customer dedicated analysis of dynamic drive system problems as an engineering service on a fixed price rate.

Software programs can also be purchased directly from ARLA. According to ARLA's cooperation with ITI we offer the simulation software ITI®-SIM for Windows. Another available software package is ARLA®-SIMSTAT, which is only used to simulate the steady-state behaviour (simulation in the frequency domain).

Examples realized by ARLA^®-SIMUL:

1. Visualization of a ship drive system (here: coloured mode of vibration for the 5th natural frequency)

2. Run-up of a synchronous motor drive (run-up with typical resonances)

3. Simulation of a run-up of a drive system with gear including an amplitude map (resonance diagram) (several resonances due to the mesh frequency)

4. Simulation of a manual transmission of a car including an amplitude map (resonance diagram) (quasi-stochastic behaviour due to backlash in the gear stage; example: gear-rattle effects in manual transmissions of cars and trucks)
