Optimization an arrow no-failure operation probability of the shovel excavator

Abstract

Optimization an arrow no-failure operation probability of the shovel excavator

Kotesova A.A.

Optimization an arrow no-failure operation probability for set fatigue resource of an arrow as base detail of the shovel excavator is important economic task.
Optimum value of no-failure operation probability can be received as a result of consideration of various options of manufacturing of an arrow of the excavator.
Thus at no-failure operation probability Р=0,999 for 20 thousand hours, optimum option is the arrow design from steel 15ХСНД with wall thickness 12 mm.

Keywords: optimization, resource, arrow, shovel excavator
