【摘要】 电控门因其性价比合理，广范应用于大众公共安全领域。但因其设计存在较大缺陷，其合门时产生的噪音远远超过国家相关标准，造成严重噪音危害。本文密切关注了这种与大众生活相关的研究课题，通过实测实验和计算机系统仿真，重点研究了电控门工作的机理，提出了电控门噪音产生的根源是设计存在重大缺陷—电控门的安全闭合必须依靠门体正撞产生的冲击力，并且没有相关降噪措施，必然在使用造成巨大噪音的结果。 本文通过频谱分析，定量化确定了电控门噪音的主要成份，提出了针对主要噪音成份的控制方法。文中对电控门蓄能、运动系统的改进性方案，以达到对蓄能系统的改进和加强对门体运动的控制能力，基本上解决了门体安全闭合时正碰与发出噪音的矛盾。本文提出以控制噪音激励源为核心、控制噪音传播途径的综合措施来实现电控门噪音控制的具体方法，是最为简便和有效的噪音控制方法。更多还原

【Abstract】 The electric control door is widely used in public security fields because of its reasonable price performance. But the noise made when the door is closed is far beyond national correlative standards , and make serious noise pollution. The article put emphases on the mechanize of the electric control door through experiments on the spot and emulation of computer, then advance that the root of noise is that the design has defects .The safe close of the door is depended on the impulsion of door normal impacts. The design hardly has denies measures so that it is convenient to use while its noise is loud’The article analysis the prime factors of noise quantitatively through the fervency spectrum, and make the ways object to noise, in that it is suggested to improve the energy storage system and raise the system control capability to the moving door so to slow the close velocity. All this can resolve the problem of noise.To have better effects of denoise, this article propose that the core of denoise is to control the noise driving source adding to develop transmission path of noise.更多还原
