Calculation and substantiation of the rational parameters of a spring finger of a heavy stubble harrow
The dependences of working stresses in coils of spring fingers of heavy dent-spring harrows are analytically deduced, the main causes of destruction of spring fingers are revealed; on the basis of research, a substantiation of the sizes and design parameters of the spring fingers is presented from the condition of absence of fatigue damages. Keywords: HARROW, SPRING FINGER, FATIGUE FAILURE, SAFETY FACTOR, MECHANICAL CHARACTERISTICS, BENDING, TORSION, SHAPE OPTIMIZATION
