Abstract

It is difficult to use traditional bearings for the telescope base in extreme environments, and the use of spliced arc guides can solve this problem. This paper studies the change of the friction force of the arc motion rolling guide under the condition of splicing error. In this paper, simulation methods are used to explore the speed change of the arc guide under different splicing error conditions, the Coulomb model is used to calculate the friction force change, and then the polynomial fitting is used to observe its fluctuation. The research results show that when the splicing error is 0.005 mm and 0.01 mm, the friction force of the arc motion rolling guide is roughly 10-15 N. Moreover, when the splicing error is 0.01 mm, the frictional force changes more discretely.
