Title
Mirror Vibration Evaluation Procedure
GM Worldwide
Publication Date:
Jul 1, 2005
Scope:
The Operating Data Master Test Procedure, GMW14227, shall be
referenced for more detailed
information corresponding to the following procedure.
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.
To determine the first resonant frequency and the dynamic rotation of
all mirror assemblies as
mounted to ground.
Forward.
The first natural frequency of a component or subsystem characterizes
the capability of that
component or subsystem to couple to vehicle structural natural
frequencies and operating inputs.
First resonant frequency is a criteria for mirror vibration
performance.
Dynamic rotation is a criteria for mirror blur.
Applicability.
This procedure is valid for use with all OSRVM and ISRVM assemblies.
Definitions.
Unless otherwise specified, all definitions are contained in GMW14227.
ISRVM:
Inside Rear View Mirror.
OSRVM:
Outside Rear View Mirror.
Frequency Response Function (FRF):
A frequency response function is defined as an output/input
relationship of a system as a function
of frequency.
Transmissibility:
A type of FRF where both the output and input are measured responses.
