Computer-aided tolerancing (CAT) aims to predict and control geometrical and dimensional
deviations in the early design stage. Former simulation models based on the translation and …

Tolerance analysis aims to ensure the performance of mechanical products. However,
traditional analysis methods largely ignore the effects of form errors and local surface …

Tolerance analysis aims on checking whether specified tolerances enable functional and
assembly requirements. The tolerance analysis approaches discussed in literature are …

Geometric errors are inevitably observable on machining parts and have huge influences on
the assembly quality and precision of mechanical system. The modelling of geometric errors …

This paper introduces a novel modelling method for variation propagation calculation of 3-D
assemblies taking into account geometric variation and part deformation, which are …

The aim of tolerance analysis is to find a balance between manufacturing cost and product
geometric quality. Earlier research usually considered ideal surface-based deviation models …

Managing geometric part deviations to control their effects on the product function and
quality is an important task in the design of physical artefacts. Consequently, computer …

The precision spool valve is the core component of the electro-hydraulic servo control
system, and its performance has an important influence on the flight control of aviation and …

Assembly accuracy analysis plays a very important role in verifying whether the design
scheme of geometric accuracy in the product design stage can meet the functional …

Geometric variations and uncertainty are generally observed on every manufactured
workpiece and have a critical influence on the functional performance of mechanical parts …
