Li1 = five mm is a perfect size and Di1 = eight mm is a perfect diameter in a diameter contraction half. li2 = 7. five mm is a perfect size and Di2 = 22 mm is a perfect diameter in a diameter enlargement half. the scale of every precessed half is expressed with l1, D1, l2, D2. A filling fee is difined by way of a ratio of an exact dimension and a fantastic measurement, and is proven Eq. 1-3. utilized Mechanics and fabrics Vol. 473 1 Filling expense of diameter contraction half f1 similar filling fee f 1 zero. eight zero. 6 1 deg. θ=1° 2 deg. 2° zero. four three° three deg. four° four deg. zero. 2 zero. five 1 1. five 2 zero. eight zero. 6 zero. five 1 deg. θ=1° 2° 2 deg. three° three deg. four° four deg. zero. 2 1 1. five 2 2. five rigidity ratio σ/σy0 Fig. 7 Relation among filling expense of diameter growth half and tension ratio =1− = 1 1. five 2 2. five Fig. 6 Relation among filling expense of diameter contraction half and pressure ratio Width of diameter enlargement half l2 (mm) Filling cost of diameter growth half f2 zero. eight zero. five four° four deg. tension ratio σ/σy0 1 zero. four three° three deg. zero. 2 2. five Fig. five Relation among similar filling expense and rigidity ratio with quite a few bending angles zero. 6 1 deg. θ=1° 2 deg. 2° zero. four pressure ratio σ/σy0 = 37 10 7. five 1 deg. θ=1° 2 deg. 2° three° three deg. four° four deg. five 19 20 21 22 23 24 25 Processed diameter D2 (mm) Fig. eight Relation among width of diameter enlargement half and processed diameter with quite a few bending angles (1) ⁄ ⁄ −1 (2) (3) f1 is a filling cost of the diameter contraction half, f2 is a filling expense of the diameter growth half, and f is an an identical filling price for eluvating a multistage shaft. Experimental effects impact of Bending perspective and Axial-compressive strength. Fig. five exhibits relation among identical filling fee f and pressure ratio σ/σy0 less than quite a few bending angles θ. An identical filling expense f has more suitable in θ = 1-3 deg. at any time when a beding perspective θ is going up. however it has lowered in θ = four deg. as a result of inflicting an enormous crack and the rupture whereas processing it, and being unable to method it to the final minute. in addition, the tendency with the simplest an identical filling cost f may be proven at the situation of σ/σy0 = 1. five whilst being attentive to the tension ratio. for the reason that the plastic deformation within the diameter enlargement half is promoted while the axial-compessive strain is just too robust, and the processing of the diameter contraction half doesn't strengthen adequate. f has reduced 38 Mechanical Engineering, clever approach and utilized Mechanics similar filling expense f zero. nine zero. eight 22°60rpm deg. , 60rpm 22°120rpm deg. , 120rpm zero. 7 60rpm 33°deg. , 60rpm 120rpm 33°deg. , 120rpm zero. 6 zero. five 1 1. five 2 2. five pressure ratio σ/σy0 Fig. nine Relation among similar filling expense and tension ratio with a variety of rotating speeds Width of diameter enlargement half l2 (mm) eight 1 7. five 2°60rpm 2 deg. , 60rpm 2°120rpm 2 deg. , 120rpm 3°60rpm three deg. , 60rpm 3°120rpm three deg. , 120rpm 7 21 22 23 Processed diameter D2 (mm) Fig. 10 Relation among width of diameter growth half and processed diameter with a variety of rotating speeds with the exception of θ = three deg. whilst σ/σy0 = 1.
