Comparison of predication results of different modeling methods.

Prediction value	General linear regression analysis	Normalized regression model	RSM	Stepwise regression analysis	Range analysis and variance analysis
Speed drop	0.847	0.801	0.883	0.899	The oil pressure is the main factor affecting speed drop and engine speed is the main factor affecting dynamic load and sliding friction.
Dynamic load	0.893	0.833	0.918	0.831
Sliding friction	0.844	0.391	0.886	0.887
