Dynamic evaluation of industrial drive systems

Dynamic evaluation of industrial drive systems involves directly accounting for irregularities stemming from the motor or load unit, and analyzing transient operating conditions. It includes the detection and "detuning" of torsional drive vibration and belt flapping, necessitating dynamic belt parameters. The process utilizes empirical borderline values for drive evaluation and conducts a detailed assessment of noise, vibration, and harshness (NVH), along with stress results. Moreover, it encompasses the evaluation of comprehensive dynamic results, incorporating integrated feedback.​

E-Motor Piston Compressor

High compressor torque irregularities:
Problem: Critical belt flapping

Task: Find a configuration with reduced belt flapping in the entire speed and load range



  • Dominating torque irregularities from compressor

  • E-motor requires a torque based speed control (fixed speed excitation detunes the system)

E-Bike Drive

High tooth load after increasing the system power
Problem: Reduced belt life caused by tooth cracking

Task: Suggestion of design changes to reduce tooth load and wear


  • Static



  • Unequally distributed tooth forces on the driver sprocket Force transmission by friction and tooth force

Packing Machine

Oscillating inertia driven loads:
Problem: Understanding the belt durability differences in layout variants

Task: Optimization of drive parameters to reduce tooth wear


  • Oscillating inertia driven loads, Implementation of a ‘Inertia-Variator element’ to replicate   the complex kinematic system by reading the customers inertia characteristic


Motor setup:

  • Detailed motor and controller model based on data sheets and customer performance tests

E-Power Steering Unit

Belt vibrations

Problem: Structural NVH issues

Task: Understanding the design changing effects to the systems NVH behavior

  • Craig Bampton Reduction for the housing to replicate the accelerometer results at certain mount points

  • Functional mock up unit (FMU) to integrate the steering control as “black box” into the MBS software

  • Simulation of maximum steering force operations (left/right)

  • Belt and engine as source of vibrations, bearings, coupling stiffnesses, clearances and the housing as a complex non-linear transfer path and resonator
