To better analytical sound design and engineering practice combined , some shortcomings for its existence was perfect and expand . Improve the robustness of the design theory based on the development of robust design software to achieve robust design automation , in this paper, the structure and operation of the sound design software to do a simple introduction . The borrowed sound design software , on the the milling machine YH53200 Spindle Box robust design , verify the theory and software , provides a theoretical basis to further improve the robustness of the headstock . The paper is organized as follows : 1 ) describe the research status of the robustness of the analytical design , Kriging surrogate model , briefly the subject of the proposed and studied significance , the study of the subject content . 2 ) analytical robust design process , a generic model . Noise variables into the analytical sound design theory , improve the robust design model , and discuss the correlation between each variable degrees of processing methods . Solving strategies and multi-objective Kriging surrogate model robust design -oriented analytical methods were introduced . 3 ) improve the robustness of the design theory to develop a robust design software , the paper describes the robust design of the software structure , process , database structure , key technology and integration methods . The derivation of the formula for the mean and variance based on symbolic computation , automatic processing of multi-objective Pareto solution , Kriging surrogate model automatically build the technology to do the highlights . 4) robust design features of the software , interface operation, introduced by the order of the module division and Zhang Jian papers variance model robust software design boundary model robust design and tolerance model robust design validation , verify the results show that the software results entirely credible and reliable . 5) as an example the milling machine YH53200 headstock robust design , to borrow the prudent design software were taken analytical method and agent model for robust design . The analytical method can quickly locate the soundness of the headstock , but with less accuracy , long design cycle of the agent model method , but the accuracy is higher , in line with the requirements of engineering practice . Verify the the prudent design theory and software design results of the two methods to further improve the robustness of the headstock provide a theoretical basis .
