| 摘 要： | 按ISO／DP7905／4标准的要求，研制了小型轨瓦疲劳试验机，它可应用实物轴瓦进行合金材料疲劳强度试验，为确定试验载荷、瓦口径向变形与试验应力三者间的关系，按复合曲梁理论建立了有关公式，并用有限元法及电测法对这些公式进行了校核，证明了完全满足精度要求。

| Abstract: | A newly developed fatigue testing machine for small bush was developed in accordance with ISO/DP7905/4,which can be used to test the fatigue strength of bush coated with bearing metal.According to the theory of composite curved beams,some related formulae have been established to determine the relationship among testing load,radial deformation of guage dia and testing stresses.Being checked with FEM,the electrometric method shows that these formulae meet the requirement of precision. |
