The Relationship of Automotive Balance Limits to Human Perception 2004-01-0401
A large number of production balance limits have been collected from various automotive related fields, ranging from electric motors to heavy duty truck assemblies. The production balance limits when normalized will be shown to have very similar ISO balance limits classification. They have been related to two sets of standards: balance limits for machinery and limits for human perception. The change of tolerances for some components over the last several decades will be considered, and it will be shown that these production balance limits now are closely related to limits for human perception.
