Scope:

Note: Nothing in the specification supersedes applicable laws and regulations unless specific exemption has been obtained.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose.

Procedure for approximating dynamic stiffness of the body side steering column attachment interface.

Foreword.

The driving point dynamic stiffness of an effective steering column attachment point is used to allocate stiffness requirements to the steering column and IP structure. The intent is to achieve a target in-vehicle resonant frequency of the steering column. The resonant frequency of the steering column can affect customer level perceptions of rough road shake, idle shake, and structural feel.

Applicability.

This evaluation procedure is appropriate for analysis of all body structures.
