Three levels of fan structural analysis are included in this practice:<\/div>\n
    \n
  1. \na<\/span><\/p>\n
    Initial structural integrity.<\/div>\n<\/li>\n
  2. \nb<\/span><\/p>\n
    In-vehicle testing.<\/div>\n<\/li>\n
  3. \nc<\/span><\/p>\n
    Durability (laboratory) test methods.<\/div>\n<\/li>\n<\/ol>\n
    The initial structural integrity section describes analytical and test methods used to predict potential resonance and, therefore, possible fatigue accumulation.<\/div>\n
    The in-vehicle (or machine) section enumerates the general procedure used to conduct a fan strain gage test. Various considerations that may affect the outcome of strain gage data have been described for the user of this procedure to adapt\/discard depending on the particular application.<\/div>\n
    The durability test methods section describes the detailed test procedures for a laboratory environment that may be used depending on type of fan, equipment availability, and end objective.<\/div>\n
    The second and third levels build upon information derived from the previous level. Engineering judgment is required as to the applicability of each level to a different vehicle environment or a new fan design.<\/div>\n
    This SAE Recommended Practice is applicable to any engine cooling fan application including medium and heavy-duty trucks, buses, construction equipment, industrial, and agricultural equipment. Some sections are more applicable to engine-driven fans than to hydraulic-driven or electric-motor-driven fans, especially with respect to speed control. Fan failure modes, however, are generally the same regardless of driving modes.<\/div>\n
    The usage of non-metallic construction necessitates areas of evaluation not required by metallic designs. Chief among these are temperature extremes, moisture content, impact resistance, chemical attack, material purity\/homogeneity, and aging\/weathering. Areas of evaluation affecting both metallic and non-metallic fans, but requiring somewhat different approaches with non-metallic parts, include natural frequency determination and durability testing.<\/div>\n","protected":false},"excerpt":{"rendered":"
