内燃机工程法噪声测试试验室规划建设

Planning and Construct of the Laboratory for Noise Test of Internal Combustion Engine Conform to the Engineering Method

介绍国家标准中使用工程法测试内燃机噪声声功率对声学环境的要求。介绍国内某一内燃机试验室为适应国家标准的要求,对原有试验空间进行计算规划的情况。同时为解决实际测量过程中可能遇到的困难进行了分析,并提出解决方案。

Introduced the national standard method used in the engineering method of internal combustion engine noise sound power of the acoustic environment requirements. Introduced a domestic internal combustion engine laboratory in order to adapt to the requirements of national standard, to calculate the original test room space planning. At the same time, in order to solve the difficulties of actual measurement process may encounter in analyzing, we put forward solutions.
