| Abstract: | The transfer matrices of twelve basic tractor reactive muffler components with mean floware established,based on the acoustic transfer matrix theory. As a check,two examples arecalculated and good agreement exists between the calculated and measured results at most offrequencies. The better agreement will exist if the noise effect generated by air flow can betaken into consideration. Nevertheless,the acoustic silencers can be designed with these ma-trices successfully and conveniently in engineering practice. The results studied in this papercreat a favourable condition for the optimum design of tractor reactive exhaust mufflers. |
