wheel damper meaning in English
车轮减震器
Examples
- Then according to the demand of the wheel damper and the characteristic of the tread vibration and the web vibration , a new type of wheel damper was designed and produced
再次,根据车轮阻尼器的设计要求,结合车轮踏面和辐板振动的特点,设计了新型车轮阻尼器。 - The railway companies have embarked on noise abatement programmes . they have carried out regular rail and wheel grinding , installed wheel dampers , replaced motor alternators with quieter alternative and erected track - side barriers at locations close to residential areas
各铁路公司已实施噪音消减计划，包括定期打磨路轨和车轮加装车轮减震器换上更宁静的电动交流发电机，以及在铁路沿线住宅区加设隔音屏障。 - Secondly , experiments were made to analyze the effect of the wheel damper , we used the system composed of a self - made pendulum , three acceleration sensors , a four - channel charge amplifier , a sound level meter , a signal collection analyzer and the dasp software
其次,对车轮阻尼器的降噪效果进行实验分析。实验采用激振单摆、加速度传感器、电荷放大器、声级计、智能信号采集处理分析仪以及dasp软件组成的测试系统。 - We did some analysis about the relativity between the vibration and the noise of the wheel . after the testing of the first line of guangzhou underground , we found that the existing wheel damper has nothing to do with the noise of wheel less than four thousands hz . compared of different contributions of the tread vibration and the web vibration on sound level of railway noise
在实验过程中,改进了对车轮的激振方式,利用单摆激振提高了激振力的精度;实验分析了车轮阻尼器的结构、安装方式及其动力学参数对车轮阻尼器降噪效果的影响;也分析了车轮振动与噪声的相关性;现场测试广州地铁一号线的噪声特性,确定了车轮阻尼器所要控制的频率范围;对比分析不同激振情况下,踏面径向振动与辐板轴向振动对噪声声压级的贡献比例。 - The noise reducing performance of the wheel damper is supposed to be improved . at last , we did lots of experiments about kinds of factors , which have some influence on the effect of wheel damper , and ascertained the best parameters of damper and the best place to fix it . compared the amplitude - frequency
分析不同的安装方式以及阻尼器参数对车轮阻尼器降噪效果的影响及其规律;确定降噪效果最佳的阻尼器参数以及安装方式;比较新型阻尼器与原有阻尼器受到相同激励时所产生噪声频谱。
