起重机运行自动纠偏及治理啃道系统开发

起重机大车运行啃道是一个普遍现象，它给企业造成相当大的经济损失。提出用位移传感器测量出起重机车架相对于轨道的偏斜，用此伯斜量作为控制信号，通过变频器调整两边驱动电动机的转速，从而自动地修正车架的伯斜，并加强车架的水平刚性，使啃道现象得以基本消除。作者将此设想已用于起重机模型的实际运行中，取得了良好的效果。

基于减振降噪分析的高效堆垛机设计

物流业的快速发展,使得堆垛机趋向结构大型化和运行高速化。而随之出现的是振动过大及噪声污染问题,既影响产品的动态性能,又存在着安全隐患。为解决上述问题,从堆垛机的结构入手,重点分析振动和噪声产生的主要原因,运用SolidW orks(三维绘图)及其插件Cosmos/W orks(有限元分析)、Cosmos/Motion(动态仿真)软件,通过对不同结构参数和不同结构形式的(超高速/大高度)高效率堆垛机的三维建模、动态仿真与有限元分析,评价其模态和频率指标,摒弃原设计的等截面形式而采用效果最佳的变截面结构形式。结果表明,改进的设计满足设计规范要求,并进一步总结和分析应当重视的问题,对解决高效率堆垛机振动过大和噪音污染问题具有现实的指导意义。

Pre-evacuation path planning in chemicals-concentrated areas with risk assessment and individual character analysis

With the ever-increasing development of those chemical parks (concentrated areas), the inherent hazards may remain the major leading cause of serious casualties, causing dramatic increases in deaths and injuries. Despite this, proper path beforehand can effectively minimise the number of deaths or injured. In this study, in order to better address the aforesaid issue, the pre-evacuation path planning was adopted to do so. This method can serve to prepare emergency response in case of extreme events, such as fires, explosions, or dangerous leakages, because these accidents could happen in chemical parks (concentrated areas). To that end, a framework was therefore proposed. First, the general risk representation was conducted. After the main hazards as well as the vulnerability within the facilities was identified, the interaction between those two factors could be expressed with matrices. This was followed by the analysis of the domino effect, which tends to occur under such circumstances. Second, individuals' visibility and inclination at each location to choose the nearest exit gate or shelter zone were analyzed by space syntax analysis. Third, a weighted risk map mainly composed of risk, individual's visibility, and inclination of exits was therefore generated. And the lowest cumulative risk path was simulated and analyzed accordingly. Finally, the map modified with received risks suggests that each individual's safest route from their current locations can be possibly simulated with Dijkstra's algorithm, which corresponds to the lowest cumulative risk. For the purposes of illustration and validation, a real case was adopted. The results demonstrated that this framework could provide both technical and theoretical support for the pre-evacuation path planning in chemicals-concentrated areas like chemicals-concentrated areas.
