Abstract: The pavement distress has considerable influence with drivers. Considering the fact that the forms of asphalt pavement potholes, subsidence and cement pavement potholes (collectively defined as pavement pothole-subsidence) are similar and they can influence traffic flow significantly, we put forward to use indexes such as Tangential Diameter Length, Normal Diameter Length, Depth, Lateral distance, etc to describe the characteristics of pothole-subsidence. According to different wheel paths & speed, driving modes was classified into several types, influences of various pothole-subsidence on driving mode and speed was analyzed.

Abstract: Considering the fact that the forms of asphalt pavement potholes, subsidence and cement pavement potholes (collectively defined as pavement pothole-subsidence) are similar and they can influence traffic flow significantly, we put forward to use indexes such as Tangential Diameter Length, Normal Diameter Length, Depth, Lateral distance, etc to describe the characteristics of pothole-subsidence, and we also adopt AutoScope-2004 video detection system aided by artificial judging to investigate in the surveyed road section. According to different wheel paths, driving modes was classified into three types, influences of various pothole-subsidence on driving mode and speed was analyzed. We came up with conclusions as follows: one is that pothole-subsidence significantly influenced the variation of vehicle trajectory, 78.5% vehicles altered their driving direction, and the average rate of speed descent is over 20%.

Abstract: The effect on the feeding rate and feeding stability of the multi-point piezoelectric vibratory feeder, of various factors such as driving mode, operating frequency and input signal phase difference is analyzed in detail through many experimental researches by means of the multi-point piezoelectric vibratory feeder developed by ourselves. It is found that the driving mode has critical influence on the conveying performance of the multi-point piezoelectric vibratory feeder. Symmetrical two-point, front single-point and rear single-point vibration sources, these three driving modes have their conveying performance relatively stable. However, three-point, asymmetrical two-point and bottom single-point vibration sources, these three driving modes have their feeding rate somewhat lower than that of the former three modes in the same conditions and their conveying performance is extremely unstable. In particular for the driving mode of single-point vibration source with the bottom close to the rear, conveyance of materials is almost impossible. The effect of phase difference is represented in the driving mode of multi-point vibration sources.

Abstract: This paper analyses the kinetic trajectory of abrasives both in initiative driving mode and passive driving mode, and the uniformity of lapping trajectory of the two opposite drive modes is discussed, respectively. The imperative relation between the kinematic trajectory and the uniformity is researched in this paper, as well as the simulation of the lapping trajectory.
