Dimensional Variation Analysis for Rigid Part Assembly With an Improvement of Monte Carlo Simulation
Publikováno v:
IEEE Access, Vol 8, Pp 5862-5872 (2020)
Dimensional variation has significant effect on the quality of product. Recently, Monte Carlo (MC) simulation is widely used in dimensional variation analysis, with high accuracy and adaptability, but there is the problem of low computational efficie
