Simulation and laboratory studies on the influence of selected engineering and operational parameters on gear transmission vibroactivity

The optimization of the construction of gears leading to the minimization of dynamic effects and to meet all basic criteria is in many cases only possible by applying numerical methods. The models allow determining the influence of a range of factors on the dynamic phenomena. Proper experimental tests are often not possible because the number of options of influencing factor sets is very large. Using simulation models allows limiting the volume of experimental studies to the necessary minimum, and hence is beneficial from the economic standpoint. The paper describes numerical and laboratory researches on the influence of selected construction, technological and operational factors on the dynamic effects and vibroactivity in gears. Numerical analyses were performed using a custom-developed dynamic model of a test stand with the gears operating in the circulating power system. The model's details were presented at the International Congress on Technical Diagnostics in 2008. The idea behind this article is to present selected results of simulation calculations and laboratory tests to determine the possibility of minimizing the noise and vibration of gears. Selected results of the calculations were also compared with the results of laboratory tests to demonstrate the high compatibility of the two test methods.
