Cause Analysis and Process Optimization of Non uniformity of FRP Anti current Vibration Carrier Shell
Dalian Scientific Test & Control Technology Institute, Dalian 116013, China
For improving the test system, it needs to build measuring carrier and optimize shell design. To obtain valid and reliable test data, it needs the measurement uncertainty of test system with 3dB.But the test results show the measurement of results between the inside and outside the shell are quite different. This has great impact on the measurement results. This paper carried out cause analysis from five links of people, machine, material, method, environment for sound transmission performance of FRP housing. It found out the main reason of poor sound transmission of FRP housing, Single side vacuum adsorption molding method have been taken, good results and expected purpose have been achieved.
Key words: sound transmission / FRP shell / Single side vacuum adsorption molding method.
