Abstract:

As wind power equipment is heavy and long,it requires a special highway to transport,which belongs tospecial equipment transportation.As there is no specification for the highway alignment design of large-scale windfarms in the mountainous areas in China,the relative indexes of aerogenerator transportation vehicles are systemati-cally investigated in this paper,and a typical vehicle for aerogenerator transportation is analyzed in terms of the dy-namic performance,the grade ability under different actual loads and the ideal maximum and unlimited-length lon-gitudinal grades.Next,a dynamic performance diagram is drawn up,and the balance velocities of the typical vehi-cle on different gears and grades are calculated.Then,the maximum climbing grades at different elevations underdifferent loads are obtained,and the ideal and unlimited-length maximum longitudinal grades of the typical vehicleunder different loads are figured out.Finally,the usual and limited values of the maximum longitudinal grade arerecommended for the large-scale aerogenerator transportation at different design speeds.Specifically,the limitedvalue of the maximum longitudinal grade with an actual load of 80t is recommended to be 14.5%.The results canprovide guidance for aerogenerator transportation highway design and construction,and can also be used to formu-late standards relevant to aerogenerator transportation highways.
