The article focuses on the friction stir welding (FSW) robot and introduces the system structure of it as well as five kinds of typical welding conditions. Through establishing the six dimensional stiffness model of guide screw's joint and presenting a numerical simulation method of flexible joint, this paper improves the accuracy of the engine's finite element model, and then analysis the effect...
The sealing process of packer rubbers is analyzed by finite element methods with the ANSYS software in the paper. It introduces in detail the principles of the packer's sealing, elaborates the elementary theories of the finite element analysis and the methods to determine the model parameters, establishes the finite element analysis models of the packer rubbers, analyzes the relationship between the...
