Abstract:
Transmission of stress wave through the mechanical impact system is
studied with the aim to provide an approach to synthesize all parts with
the same wave transmissivity as a given part. The given part is divided
into a finite number N of segments with constant cross-sectional area
and equal transit time, as a consequence the matrix equations are
established to represent the transmission of stress waves.
Characteristic matrix and transmission equivalent are defined and
discussed. By means of an inversion approach, all parts which are
transmission equivalent to the given part can be obtained through
substitutions. It is mentioned that there are at most two to the power N
different. Numerical examples are given for cases with N =2, 3.
Key words:
