A parametric finite element modelling program was developed orienting to the special structure of the front frame of a loader, and the modelling method was introduced in detail as well as the structure and subroutine of the program. Model data file used by ADINA software was also generated through converting data format. The finite element strength calculation and analysis on the front frame of ZL60D were developed. Modified suggestion to the design based on the calculation was presented. The calculated results proved that the model program is accurate and useful.
