摘要
针对导轨不平顺作用下曳引电梯轿厢的水平方向振动问题,对导轨在不同激振频率下电梯轿厢的动态特性进行了研究。设计了一套滚动导靴-导轨接触式电梯实验系统,该系统主要包含:电梯轿厢模型、滚动导靴装置以及激励系统;根据电梯系统零件繁多,轿厢、轿架结构件非标准化的情况,以及电梯固有频率经验值、相似性原理,建立了水平电梯振动分析实验平台,保证了实验系统与理论分析的契合性;将Lab VIEW数据采集技术应用到导轨的受迫振动实验中,利用DH1301型激振器给予其中一侧导轨两种不同频率的正弦激励,进行了测试,并收集了轿厢3个不同位置的水平振动加速度实验数据,并对其进行了频谱分析。研究结果表明:在不同的正弦激励频率下,激振频率越接近系统固有频率值,质心处水平振动加速度响应幅值越大。
Aiming at the problem of horizontal vibration of the elevator car under the action of uneven rails,the dynamic characteristics of the elevator car at different excitation frequencies was studied. A rolling guide-rail contact elevator experiment system was designed,which mainly includes elevator car model,rolling guide device and excitation system. According to the various parts of the elevator system,the car and car frame structural parts are not standardized,the elevator natural frequency experience value and the similarity principle,a horizontal elevator vibration analysis experimental platform was established to ensure the compatibility of the experimental system with theoretical analysis.Lab VIEW data acquisition technology was applied to the forced vibration experiment of the guide rail. The DH1301 exciter was used to test the sinusoidal excitation of two different frequencies on one side of the guide rail. The experimental data of horizontal vibration acceleration at three different positions of the car were collected,and the data was analyzed. The results indicate that under different sinusoidal excitation frequencies,the excitation frequency is closer to the natural frequency of the system,and the amplitude of the horizontal vibration acceleration response at the centroid is larger.
