Stress Analysis and Structure Optimization of Main Landing Gear Frame Front Fork Based on Workbench
Based on main landing gear frame front fork root of a certain aircraft multiple occurrences of fatigue crack
the front fork as main landing gear frame key-module
seriouly influence safety of the landing gear. Through stress analysis of the structure using ANSYS Workbench simulation softwarely
weak positions of the frame front fork were obtained
and its structure and comparative analysis were optimized by combination of topology optimization and goal driven optimization method. Obtained weak parts were in conformity with the actual usage
structure is reasonable
stress obviously improved
and weight decreased by 17.3% than before optimization.
