Contact pressure analysis of pin-loaded lug with clearance

In engineering design, none of the existing models for calculating contact pressure in pin-loaded lug is fully compatible with actual working conditions. order to obtain a more accurate formula maximum lug, after verifying reliability finite element model PRESCALE measurement film, single-parameter and multi-parameter analysis two types factors affecting distribution compressive surface were conducted elastic state. The influence relevant design parameters on its was obtained, based Hertz stress introduced. It verified by large number samples that predicted values are good agreement solutions range common scales have high accuracy, which can be used reference.
