摘　　要：本文旨在根据电梯电机的工作特性,优化传统的电梯电机运行噪声的检验方案,解决电梯低噪音级噪声难以检测和抑制的问题。电梯的运行噪声是使用电梯时的焦点问题,电梯电机在工作中产生的噪声是最难以检测和抑制的部分。本文通过探讨现有电梯电机运行噪声的检测和抑制方法的局限性,在原有的采用声级计针对高噪音级噪声的检测的基础上,选取采样范围更广计权方式更合理的声音传感器对低噪音级噪声进行检测;在噪声抑制上开创性的使用振动传感器进行检测,量化电机运行时的机械振动噪声并明确声音的传播路径。将声音传感器和振动传感器两者相结合,从空气动力、电磁振动和机械振动噪声三个方面入手,提出了电梯电机运行噪声的检测和抑制的新思路,提升了电梯电机运行噪声的检测方法及抑制措施,完善了特种设备检验机构在电梯噪声检测和委托服务上的技术手段,提高了特种设备检验机构在该方面的检验能力。This article aims to optimize the traditional inspection scheme for elevator motor operation noise based on the working characteristics of elevator motors,and solve the problem of difficulty in detecting and suppressing low-noise level noise in elevators.The running noise of elevators is a key issue when using elevators,and the noise generated by elevator motors during operation is the most difficult part to detect and suppress.This article explores the limitations of existing methods for detecting and suppressing the running noise of elevator motors,on the basis of using sound level meters to detect high noise levels,a sound sensor with a wider sampling range and more reasonable weighting method is selected to detect low noise levels;pioneering the use of vibration sensors for noise suppression,quantifying mechanical vibration noise during motor operation and clarifying the propagation path of sound.A new approach for detecting and suppressing elevator motor operating noise is proposed by combining sound sensors and vibration sensors,starting from three aspects:aerodynamics,electromagnetic vibration,and mechanical vibration noise,improved the detection methods and suppression measures for elevator motor operation noise,improved the technical means of special equipment inspection agencies in elevator noise detection and commissioning services,and enhanced the inspection capabilities of special equipment inspection agencies in this area.
