【摘要】：基于摄像测量学,为扶梯链传动的横向振动设计了一套非接触式测量系统,对理论结果的验证提供了有效实验方案。首先介绍了系统组成及实验装置,结合振动特性提出了定点检测和链节追踪两种研究方案,接着考虑实际扶梯参数进行实验测量和数据处理,最后将实验数据与理论参数对比,验证了方案高效实用。结果表明:扶梯运行中,驱动链条振动幅值中间较大,向两边递减,且松边的振动幅值要远大于紧边;通过FFT变换知,紧边的单个链节振动频率接近于链条与链轮的啮合频率。
[Abstract]:Camera based on surveying, design a non-contact measurement system for transverse vibration of escalator chain drive, to verify the theoretical results provide an effective experimental scheme. First introduces the system composition and experimental device, combined with the vibration characteristics of proposed fixed-point detection and tracking two link research programs, then consider the actual parameters of the experimental escalator measurement and data processing, the comparison between experimental data and theoretical parameters, the scheme is proved effective and practical. The results show that the escalator running in the middle of the chain drive vibration amplitude is larger, on both sides, the vibration amplitude and the loose side is much larger than the tight side; through FFT transform, single chain meshing frequency vibration frequency of the tight side close to the chain and sprocket.
