Study on Pulsations of Reciprocating Compressor Piping Systems : 2nd Report, Model Experiment of Natural Frequency

抄録

The paper deals with the experiment conducted for examining the calculation method of natural frequency of a complicated piping system connected to a reciprocating compressor, which is described in the preceding paper. Experiment is conducted on 5 cases such as (1) Helmholz's resonance chamber, (2) piping with different sections, (3) piping with 2 inflow lines, (4) piping with bypass line and (5) general complicated piping, which are chosen as the combination of typical examples of elements. Experimental models used are made of vinyl chloride and resonant frequency and vibration mode then are measured by exciting the piping from one end by the loud-speaker. The results of experiments very well coincide with those of calculation and ascertain the applicability of the calculation method of the natural frequency in the preceding paper.
