... to provide more accurate assembly results for tolerance analysis. As a kind of large and complex equipment, centrifuges have a large assembly workload, complex component coordination and difficult to control the assembly deviations (Wen et al., 2023), the current assembly guidance mainly relies...

...Guodong Sa; Haodong Bai; Zhenyu Liu; Xiaojian Liu; Jianrong Tan Purpose The assembly simulation in tolerance analysis is one of the most important steps for the tolerance design of mechanical products. However, most assembly simulation methods are based on the rigid body assumption, and those...

... calculations and tolerance values computed by the automated method are very closely matching. Practical implications Tolerance analysis is an integral part of product development that directly influences the cost and performance of a product. Apart from the academic interest, the work is expected to have...

...Tuan-Hui Shen; Cong Lu Purpose This paper aims to develop a method to improve the accuracy of tolerance analysis considering the spatial distribution characteristics of part surface morphology (SDCPSM) and local surface deformations (LSD) of planar mating surfaces during the assembly process...

... by statistical tolerance analysis based on the unified Jacobian-Torsor method. Findings The effectiveness and superiority of the proposed model in comprehensive tolerance characterization of discrete surfaces are successfully demonstrated by a case study of a phased array antenna. The tolerance is evidently...

...Chuanyuan Zhou; Zhenyu Liu; Chan Qiu; Jianrong Tan Purpose The conventional statistical method of three-dimensional tolerance analysis requires numerous pseudo-random numbers and consumes enormous computations to increase the calculation accuracy, such as the Monte Carlo simulation. The purpose...

... interesting concept that can be extended to other corresponding fields of the tolerance design and the quality control. The several studies have been conducted to develop the tolerance analysis of mechanical assemblies. Wade (1983) presented the tolerance charting method for the tolerance analysis...

...Ting Liu; Yan-Long Cao; Qijian Zhao; Jiangxin Yang; Lujun Cui Purpose The purpose of this paper is to carry out an assembly tolerance analysis by means of a combined Jacobian model and skin model shape. The former is based on small displacements modeling of points using 6 × 6 transformation...

..., is always difficult to satisfy the design requirements. Aerospace Assembly Tolerance analysis Assembly error Coordination dimension chain With the inconsistency phenomenon that mentioned above, it can be explained that the transfer mechanisms of assembly error and coordination error...

...Rocco Ascione; Wilma Polini Purpose The purpose of this paper is to compare two different tools for tolerance analysis. Tolerance analysis is an important task to design and manufacture high-precision mechanical assemblies; it has received considerable attention in the literature. Many...

... for the tolerance simulation. The paper aims to present a tolerance analysis process of the composite wingbox assembly considering the preloading-modified distribution and especially focuses on the spring-in deviation of the thin-walled C-section composite beam (TC2B). Design/methodology/approach Based...

...Wilma Polini; Andrea Corrado Purpose – The purpose of this paper is to carry out a tolerance analysis with geometric tolerances by means of the Jacobian model. Tolerance analysis is an important task to design and to manufacture high-precision mechanical assemblies; it has received considerable...
