Research And Practice On Process Strategy Of Robust Design

In this dissertation, a thorough analysis of all models of robust design in existence has been done on the basis of the systemic review of the development history and current research status of robust design.Afterwards, a new strategy of robust optimization design process of three stages based on tolerance model and Taguchi methods is advanced. This process makes full of the intense complementary action of characteristics between tolerance model and Taguchi methods. It realizes the result of high accuracy and efficiency by the application of this strategy. The process is divided into numerical and analytical model according to different optimization models.The robust design of mechanical locking device of damper test rig and practical product not only prove feasibility and efficiency of the optimization strategy of numerical model based on tolerance model and Taguchi methods, but also show good application possibility and design effects of the methodology of robust design on the design of subminiature machine and mechanical systems.Furthermore, I have completed the robust design of adjustable linear oil damper in the case of accounting for the differences of design variables and parameters. This instance proves the feasibility and practicality of the optimization strategy of analytical model based on tolerance model and Taguchi methods and embodies varieties and flexibilities of this process strategy. Moreover, the analytical ideology and conclusions of accomplishing the equilibrium between performance and cost of adjustable linear oil damper also provide very good references to the design, manufacture and maintenance of common damper.
