Space Transmission Guide Structure Feature Analysis

This thesis studies the characteristics of space transmission guide. Besides scientific designing the system and analyzing the system motion simulation, the author also makes some experiments and researches them, confirming the reasonable of the whole space of transmission guide.First of all, studying and analyzing the whole assemble process’s requirement to the space transmission combining with the existing transportation forms and delivery technology, put forward the implementation scheme that consists of straight line module, fan-shaped module and reversing module. Moreover, each module and the module connection are detail designed. In order to reduce instability caused by the polygonal effect, the scheme adopts a standard short pitch roller chain and analyzes the factors of instability that affecting chain transmission with MATLAB tool.Secondly, using three-dimensional modeling software to establish a entity model of each module and the connection part among modules. At the same time, take use of the theory of multi-body dynamics to build the simulation model. According to the design requirements, adding constraints in the system, make the simulation model much closer to the practical one. Based on the transmission guide performance requirements proposed by manipulator assembly, separately simulate each module and the connection among them under different speeds and different conditions. The simulation results check the feasibility of each module and the connection among them and reveal the rule.Finally, for a ready-made entity physical prototype, build a complete experimental platform to test each module separately. Conduct extensive testing of different modules in different speeds and different load cases, getting the basic performance parameters of each module. By comparative analyzing test data, find the actual operating characteristics of the various modules. This provides a strong basis and guidance for later improving and applying the program.
