Abstract

In this paper, influencing factors and evaluation standards of vibration on human comfort were summarized. The mainly influencing factors were analyzed including vibration acceleration, frequency, exposure time and other factors. The evaluation standards of human comfort were analyzed contrastively. The conclusion was that countries around the world have established unified body vibration comfort evaluation methods and evaluation standards on the basis of ISO series standards. The new methods and standards were also needed for special vibration and shock environment.

Abstract

Electric bicycles (EBs) are now becoming the main vehicles for short-distance trips because of their speediness, flexibility and convenience in many cities in China. However, these benefits come at a cost. This study analyzed the energy consumption and emission of pollutants at every stage of the EB life cycle (production, use, maintenance and recycling) by using Life Cycle Assessment (LCA). The environmental impacts and the energy consumption in production and use were quantified and compared with other competing modes of transport, such as bicycles, buses, motorcycles and cars. The results show that the energy consumption and emissions of pollutants by EBs occur mainly in the use stage, and specifically in the process of electricity production and battery change. The emissions of pollutants by EBs per person per kilometer are several times smaller than the values for motorcycles and cars, more or less equivalent to buses and higher than bicycles.

Abstract

To evaluate and compare the safety level of alternative plans prepared for a towing activity that bears various risks, a novel assessment framework is worked out for inshore towing operations for heavy cargo. The assessment framework mainly includes a set of criteria with hierarchical structure drawn from towing plans and evidential reasoning theory as data aggregation approach. Case study shows that the framework is rational and applicable in the safety assessment of inshore towing operations.
