MODELA prediction model of gearbox power loss based on dimensionless analysis is proposed. First, the dimensional model of gearbox power loss is established based on similarity criterion, dimensional harmony principle, and fluid mechanics p theorem. Then, the experimental study is carried out on a ...

reveal the mathematical relationship between dimensionless numbers (i.e., the scaling law). A common approach to establishing the scaling law is to leverage the results of the dimensional analysis with experimental measurements of the physical system. The experimental measurements are transformed into di...
In many cases, just a simple scaling analysis of dimensionless parameters suggests fruitful simplifications. In each case, the dimensionless variables are chosen to provide the simplest form of the resulting equations. Thus, in the various sections these variables generally differ. To avoid ...
