Introduction

Increasing demands for comfort in automotive applications as well as legal requirements for stationary systems are the drivers for constant reduction of noise in gearbox development. The pursuit of the greatest possible power density leads to electromechanical drive systems with increasingly high transmission input speeds. Current gearbox design strategies are not always effective for these new conditions.

Target Audience

Designers, calculation and test engineers who must deal with the above-listed issues.

Main Topics

Day 1:

  • Foundations of acoustics and vibration theory
  • Excitation behavior of cylindrical gears
  • Design strategies for low-excitation cylindrical gears in the areas of load carrying capacity, efficiency, and noise
  • The influence of production and gear modifications on the excitation behavior

Day 2:

  • Understanding and appropriate application of dynamic vibration models
  • Calculation and psychoacoustic evaluation of noise radiation
  • Metrological investigation of vibration and noise behavior
  • Special characteristics of bevel and planetary gears

Objectives

This seminar will fundamentally address the complete noise generation chain, from gear mesh excitation, through speed-dependent noise transmission through the shaft-bearing system, to noise radiation at the casing. Participants will learn criteria for evaluating excitation behavior as well as strategies for designing low-excitation gears. Building on this, it will be shown how vibration of the shaft-bearing system can already be considered in the design phase. Finally, participants will be able to evaluate the noise radiation of the casing and implement constructive optimizations. The seminar will be rounded off with a comprehensive introduction to experimental investigation of the vibration and noise behavior of gears.
