Static Analysis for Spring-finger of 9 KJ-1 . 4 A Forage Baler Pickup Collector
Doing static analysis is necessary for spring-finger cylinder pickup collector. Force diagrams show that the forces of spring-finger on pick up stage are more complex than the other stages. Without random force, the stress of spring-finger root is greatly less than allowable stress according to calculation results and spring-fingers have elastic de-formation, they have enough strength;random force has impact to spring-fingers, when the component force perpendicu-lar to spring-finger is greater than 24N, spring-fingers have plastic deformation. Doing the static analysis will provide theoretical basis for structural optimization of spring-finger cylinder pickup collector.
