Test Programs to Determine Performance Capability of Wheel/Rim Assemblies.

摘要

The purpose of the investigation was to obtain preliminary data on wheel and rim assemblies for a proposed Federal Motor Vehicle Safety Standard and also to provide verification and validation of test methods used by industry. Three test methods were used: (A) dynamic fatigue test, (B) dynamic cornering fatigue 90degrees, (C) dynamic cornering fatigue 40degrees. In general the test procedures followed SAE-J328A and SAE-J267. The SAE Methods need clarification and revision before being capable of being used for compliance testing by DOT. Further testing was suggested to establish definite limits of dish and impressed load in the case of radial fatigue.
