The paper mainly researches and summarizes the problems during the process of simulation designing vibrating mechanism of YZ18JA-type vibrating, studies the implement method and finds out disciplinary co-simulation model based on interface which is suitable for the development model of middle/small enterprises. Taking vibrating mechanism of YZ18JA-type vibrating road roller as an example, the implement...
Wavelet multi-resolution (WMR) and a bandpass digital Butterworth Alter were both proposed to extract structural vibration signal embedded in noisy GPS observables. The noisy observables were simulated by artificially adding random noises to a de-noised GPS time series with the sampling rate of 5 Hz. Modal parameters such as frequency, damping ratio, and modal shape coefficient were identified by...
Individual subsystems and axial errors of the TCA2003 total station (TCA2003) are introduced. An ambient test with different compensator switch settings of TCA2003 was carried out in the cantilever construction of a long span bridge, to learn how much the compensator was subject to small disturbances from wind and vibrations in the kinematic mode (3 Hz data rate). It is found that the quality of the...
Many laboratory or indoor tests have revealed the advantages of the kinematic positioning of robotic tachemoeteric systems (RTS), and outdoor applications of the RTS kinematic positioning in the high dynamic tracking are still in study. An ambient vibration test with a Leica TCA2003 total station was conducted to study the feasibility in measuring the dynamic characteristics of cable-stayed bridges...
With the development of global positioning system (GPS) receiver technology for high recording rate, it allows reliable monitoring of engineering structures, such as bridges, towers and tall buildings. A structural monitoring system based on the technology of real-time kinematic GPS (RTK-GPS) is devised for the high pylon of a cable-stayed bridge. The vibration data are collected and processed by...
