A validated simulation model is used to analyze more in-depth investigations into the influence of a stochastic course of the pitch error on the quasi-static excitation behavior.

Addressing one of the most talked about noise sources — gears.

Physical effects causing transmission noise.

“ It is very hard to find out any paper regarding ‘tiger stripes’ failure, created by electrical discharge current over the gear teeth.” I wish to have some more information on this issue + how it affects the vibration / noise signatures; why does it creates the tiger stripes profile; how deep are the pittings; why does it create the noise and the possibility of running a gear with this failure?”

  Few people enjoy cost estimating and pricing exercises. I have blogged about this topic before but thought it was worthy of another look ...

When I graduated as a mechanical engineer in 1978, I landed a job in the “cold section” at Pratt & Whitney Canada (PWC) in Montreal. In those d...
