Combat Tracked Vehicle Final Drive Analysis.

摘要

The purpose of this work effort was to furnish to TACOM an Expert Design System for the analysis of combat vehicle final drives. The system was to be tailored to account for the high stresses usually used in a military environment and to provide means of including a military duty cycle. An existing final drive was analyzed for the purpose of comparing actual test data to the Expert Design System results. The design system was then fine tuned to account for the test data. The existing final drive was then optimized for maximum life and reliability using the final form of the Expert Design System . The following work was accomplished: 1) A design analysis of the M2/M3 final drive was done; 2) Potential external influences on final drives were studied; 3) Design optimization of the M2/M3 final drive life was done; 4) An Expert Design System for final drive analysis was developed. The Expert Design System can be used to analyze any military final drive of the parallel axis gear-type where housing deflections are not significant or can be identified and torsional vibration is not significant or can be included in the duty cycle.
