The Method Used for Process Precision Prediction of Micro-assembly Based on Principle of Maximum Entropy

摘要：

　　This paper briefly introduces the principle of sub-micro precision micro-assembly system based on the micro force detection.The linear mapping of micro force-micro displacement can be obtained,which is in agreement with the experimental data.And the probability distribution density function of the fitted mapping coefficients can be derived by the principle of maximum entropy.Furthermore,the uncertainly of k is accessed.Hence,the reliability of micro force-micro displacement mapping in the assembly process is demonstrated.The experiment result shows that the assembly precision can be accurately predicted by the fitted micro force-micro displacement mapping.
