英文摘要：

In view of the defect on the supporting structure of heliostat, we design a heliostat supporting and adjusting structure that is simple and reliable, moreover, easy to assemble and test. By finite element analysis on some key unit, we prove that the structure is pretty reliable, so this article provides technological support for design of heliostat supporting and adjusting structure.
