Title: Railway sound insulation and noise reduction structure, and manufacturing method thereof
Inventor: ZHAI JUN
IPC: E01F8/00
Filed: 2018-06-08
Abstract: A railway sound insulation and noise reduction structure, and manufacturing method thereof. The structure is composed of a certain number of topographical unit members (1) arranged in a sound wave direction of railway noise. The topographical unit members (1) comprise embankments and recesses and meet earthwork balance. The embankments and a main constituent in the recesses, air, construct phononic crystal cells periodically arranged to form a one-dimensional phononic crystal structure. An elastic wave forbidden band is created because of Bragg scattering, thus enhancing the sound insulation and noise reduction performance. The embankments form an acoustic barrier and reflect sound waves. The recesses between the embankments are used to form cavity structures, enabling noise sound waves to be reflected multiple times and dissipated as thermal energy. The embankments comprise greening grass slopes and pedestrian tracks (7). Water is drained from the greening grass slopes to the recesses, and collected for plant watering to save water resources. The pedestrian tracks (7) can be used for recreation. The greening grass slopes are covered with lawns and form resonant unit members to control forward propagation of elastic waves, thus further enhancing the sound insulation and noise reduction performance.

Abstract: An NSGA-II improvement-based field bridge scheduling method. In the method, improvements are primarily made to a congestion degree calculation method and elite range control based on an NSGA-II, and an improved NSGA-II algorithm is obtained by introducing a congestion degree calculation method and an elite range containing more individual information. The improved NSGA-II algorithm is then applied to field bridge scheduling of a container storage yard, such that the operating completion time for containers in the storage yard and field bridge transition time can be reduced. Experiments are carried out on four test functions for the improved NSGA-II algorithm and the NSGA-II and NSGA-II+IMP algorithms, and the experiment results indicate that a Pareto solution set of the improved NSGA-II has better distributivity and convergence, thereby better maintaining the population diversity.
