Prediction of Operating Loads Contribution to Assembly Relation and Product Behavior
2012
Journal of Software
Preserved Fulltext
When product running, operating loads will lead to change of assembly relation of product parts, affecting product behavior. ...
Based on Jacobian-Torsor method, the Jacobian-Torsor tolerance model, considering contribution of operating loads, was extended and corrected, the assembly error (assembly relation change) resulted from ...
ACKNOWLEDGMENT The research was done thanks to financial support of the Chinese National Natural Science Foundation project 50675159 "Digital Mockup Based Key Technology of Tolerance Design and Its Impact ...
