Research on the Force Analysis of Multiple Rows and Spans of Fishery Photovoltaic Complementary Flexible Support
Flexible photovoltaic brackets are gradually being widely used in fishery photovoltaic complementary projects due to their large span,few piles,and large adjustment space for ground height.With the increase of project scale,the length and width of a single flexible array can reach several hundred meters.This article models flexible supports with different spans and analyzes their stress changes.The results show that when the number of spans calculated for continuous spans reaches 6,the error of each cable force is within 5%compared to the entire array,which can be used for approximate substitution calculation.However,the cable forces of the reverse arch cable and transverse diagonal cable vary greatly with the number of spans,and the number of spans cannot be approximated as a substitute for calculation.This study can provide reference for the approximate design of flexible supports with multiple rows and spans in the future,reducing computational workload.
