摘　　要：通过对电梯导轨支架系统进行减振改造是市场上处理电梯噪声污染的一种主流方式。通过传递路径及原理简单分析了导轨系统产生噪声的原理,并结合一个对导轨减振降噪的实际改造案例,提出了对改造效果进行评价的方案:从A声级和倍频带声压级两方面对导轨减振装置的降噪效果进行评价,并从测量的结果对其降噪效果进行了分析,初步证实了该评价方法对电梯导轨支架减振改造在降噪效果方面的有效性。同时,结合该案例提出了综合评估导轨支架减振改造对电梯安全性影响的一种方法,并给出了从动态受力支撑强度和静态强度等方面对其进行评价的方案。Reducing vibration of lifts guiderail and its bracket by modification is one of mainstream means oflifts noise reduction.The source of the noise of guide systems is simply analyzed,and an evaluation method on the effect of lifts modification is proposed by presenting a modification case of guiderails vibration and noise reduction:evaluating the noise reduction effect of guiderail vibration reduction devices by Aweighted sound pressure level and octave band sound pressure level,which preliminarily proved effective for evaluating the affection of modification with guiderail vibration reduction devices.Meanwhile,combined with the case,one means of evaluating the safety performance of the guiderail vibration reduction devices is provided,and the method of dynamic load stress analysis and static strength analysis is showed.
