TL;DR

ISO 2631 has evolved to promote research, data collection, and design guidance, yet precise vibration limits and comfort criteria remain difficult to define. The paper outlines current and future initiatives to refine ISO 2631 and offers additional recommendations. The authors analyze the standard’s underlying assumptions and evaluate its use for vehicle ride quality, emphasizing safety, efficiency, and passenger comfort.

Abstract

The evolution of the standard, which is aimed at promoting research and production of more data, and providing some design guidance, is outlined and its contents summarized. Some of the assumptions and information on which it is based are analyzed. Its application to vehicle ride quality is considered in the context of the safety, efficiency and comfort of crew and passengers. The importance of establishing the precise criteria against which vibration limits are required is underlined, particularly the difficulties of first defining comfort and then postulating appropriate levels. Some current and future work related to improving the standard is outlined and additional suggestions offered.
