Engine Cooling Fan Structural Analysis
- Ground Vehicle Standard
Three levels of fan structural analysis are included in this practice: (a) Initial Structural Integrity (b) in-vehicle Testing (c) Durability Test Methods.
The Initial Structural Integrity section describes analytical and test methods used to predict potential resonance and, therefore, possible fatigue accumulation.
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.
The Durability Test Methods section describes the detailed test procedures that may be used depending on type of fan, equipment availability, and end objective.
Each of the previous levels builds 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.
This SAE Recommended Practice is applicable to heavy-duty trucks, construction equipment, industrial, and agricultural equipment. It does not necessarily include passenger cars and light trucks.
The purpose of this document is to identify the general methodology for the structural analysis of engine cooling fans, and to provide expanded information on subset practices within the general methodology, such that a user of this practice can adapt specific subsets related to a vehicle class.
Data Sets - Support Documents
The Cooling Systems Standards Committee is part of the Vehicle Engineering Systems Group and reports to the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to engine cooling systems and components for automobiles and light trucks, heavy duty on-and off-highway vehicles and industrial equipment. All standards reflect the latest technology and industry practice through advisement, consultation and cooperation with industry, government, educational institutions, the public, other standardizing bodies, and other SAE committees and members. Participants in the SAE Cooling Systems Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties, who assist the SAE Engineering Activity Board through the preparation and presentation of technical papers at national meetings and specialty conferences.
