Mixed-Mode Stress Intensity and Crack Growth at Gear Tooth Roots Using Weight Functions and Finite Element Modelling

  • Patrick Sbusiso Africa,
  • Desejo Filipeson Sozinando,
  • Bernard Xavier Tchomeni and
  • Alfayo Anyika Alugongo

Gear tooth root cracks are serious failures mechanism in transmission systems operating under high load and speed. This study develops a mixed-mode model of fracture that incorporates weight function techniques with finite element analysis (FEA) to e...

Parametric Evaluation of Stress Field Variations in and Vibration Mode Responses of a Flywheel Within the Linear Elastic Limit

  • Kgotso Koketso Leema,
  • Desejo Filipeson Sozinando,
  • Vhahangwele Colleen Sigonde,
  • Bernard Xavier Tchomeni and
  • Alfayo Anyika Alugongo

A combined analytical model and finite element analysis (FEA) framework is used to assess how the stress field evolves together with the vibratory response of the flywheels within the elastic limit range. Results indicate that circumferential stress...

Transmission Error in Planetary Gear Systems as an Excitation Source Influencing Vibration Response and Wear Mechanisms

  • Mmabotle Letsela,
  • Desejo Filipeson Sozinando,
  • Bernard Xavier Tchomeni and
  • Alfayo Anyika Alugongo

Planetary gear systems offer compact design and high-power density, but they are strongly influenced by transmission error (TE), which originates from geometric deviations and elastic deflections. This study presents a dynamic model that integrates e...

A Low-Cost Sensing Strategy for Blade Tip Timing: An Inductive Proximity Probe Approach

  • Justin Smith,
  • P. Stephan Heyns,
  • Stephan Schmidt and
  • David H. Diamond

Blade Tip Timing (BTT) provides a superior long-term blade monitoring solution compared to strain gauges, yet its adoption in lower value turbomachinery remains constrained by sensor costs. This study explores Inductive Proximity (IP) probes as a cos...
