Development of a Carbon Fibre Reinforced Polymer for Exhaust Pipe of Two Stroke Engine

摘要

Engine noise production performance is strongly dependent on gas dynamic phenomena and hardness of the material of the exhaust systems. Careful design of the manifolds enables the engineer to manipulate these characteristics but none has treated a way to damp these vibration and its frequencies. Solidworks 2014 and Ansys workbench 4.0 are used to investigate thermal and modal analysis on a heat resistant 40% carbon glass fibre reinforced polyester resin. The steady state analysis in fig. (3), shows a temperature distribution of 193.1℃, total heat flux of 30737(W/m~2) and a direction heat flux 18565(W/m~2). Considering the transient heat analysis a temperature distribution 139.59℃, total heat flux of 170370(W/m~2) and a direction heat flux 108810(W/m~2). The modal analysis reveals a displacement of 1.4939m at 6.7011Hz in x-axis direction depicting the direction of the exhaust gas emission.
