上海电机技术研究所位于市区,负责电机产品的监检、统检,以及电机新产品的研制。当前,低噪声、低振动电机的研制很迫切,需要能精密测定噪声和振动的消声室。同时,产品中有许多船用的电机和家用电器用的电机,又需要能测试无线电干扰的电磁屏蔽室。该所没有够建两个试验室的可占用面积,且投资有限,因而委托我院设计消声和屏蔽功能兼备的消声屏蔽室。一、基本条件与设计要求该室可占用的总面积为160m~2,其中消声屏蔽间约100m~2、试验电源机组间约25m~2、测量间及辅助设施约35m~2。平面布置示意见图1。 Shanghai Institute of Electrical Technology is located in the urban area, is responsible for motor product inspection, inspection, and electrical new product development. At present, the research and development of low-noise, low-vibration motors is very urgent, and anechoic chambers that can accurately measure noise and vibration are needed. At the same time, there are many marine motor and household appliances in the product, but also the electromagnetic shielding room that can test the radio interference. The institute did not have enough space to build two laboratories and limited investment. Therefore, it commissioned our hospital to design a muffler shielded room with both muffling and shielding functions. First, the basic conditions and design requirements The room can occupy a total area of ​​160m ~ 2, of which muffler screen between about 100m ~ 2, between the test power unit about 25m ~ 2, measuring rooms and ancillary facilities about 35m ~ 2. Plan layout shown in Figure 1.
