A Study on Gear Strength by Finite Element Method and AGMA Standard

Abstract

Gear strength is the measure used to forecast the service life of gear driving system. Common methods for forecasting the gear strength include finite element method and AGMA 2101-D04 method. Although finite element method could calculate the strength with relative actual strength under the changing conditions, it consumes lots of time due to the complicated calculation. AGMA 2101-D04 method employs the equivalent form to calculate the gear strength in a short period of time, but could only be performed under the given operational conditions. Therefore, AGMA 2101-D04 method isn’t capable of forecasting the gear strength of gear driving system under the continuously changing conditions. This paper combined with the advantages of finite element method DAFUL/Drivetrain and advantages of AGMA 2101-D04 method to get the new method under the variable condition, we can do rapid calculation of the gear strength on the time domain.
