Abstract EN
Geometric deviations inevitably occur in product manufacturing and seriously affect the assembly quality and product functionality.
Assembly simulations on the basis of computer-aided design (CAD) package could imitate the assembly process and thus find out the design deficiencies and detect the assemblability of the components.
Although lots of researches have been done on the prediction of assembly variation considering the geometric errors, most of them only simplify the geometric variation as orientation and position deviation rather than the manufacturing deformation.
However, in machinery manufacturing, even if the manufacturing defects are limited, they could propagate and accumulate through components and lead to a noncompliant assembly.
Recently, many point-based models have been applied to assembly simulation; however they are mainly interested in simulating the resulting positions of the assembled parts and lack the consideration of the postprocessing after positioning.
This paper enriches the complete assembly simulation process based on skin model and presents a simple and effective posture evaluation and optimization method.
The studied approach includes a software algorithm applied to evaluate the contact state of the assembly parts and a mathematical model based on the particle swarm optimization to acquire the optimal assembly posture.
To verify the efficiency and feasibility of the proposed method, a case study on the aircraft wing box scaling model assembly is performed.
