由于选材的基本出发点是要满足配件的强度要求,所以各种强度指标都直接用于雷沃谷神玉米收割机配件断面尺寸的设计计算


材料的力学性能指标是各种各样的,如屈服极限、强度极限、疲劳极限等反映材料的强度指标;延伸率、断面收缩率等反映材料的塑性指标;冲击韧性、断裂韧性等则反映材料的韧性指标。由于选材的基本出发点是要满足配件的强度要求,所以各种强度指标都直接用于雷沃谷神玉米收割机配件断面尺寸的设计计算。至于材料的硬度指标,虽可对强度性能作出特定量的估计,也可用于配件的设计计算。测量硬度的方法比较简便,在生产实际中应用很多。【具体可参考《雷沃谷神玉米收割机配件加工需“步步为营” 切忌在质量上投机》的相关内容】
