Non-rigid compliant parts are widely used in industries today. One of the biggest challenges facing the industries is geometric variation management of these compliant parts, which directly impacts product quality and functionality. Existing rigid body based variation modeling is not suitable for compliant assembly while finite element analysis based methods have the disadvantage of requiring heavy computation efforts. In view of that, this paper develops a novel methodology to evaluate geometric variation propagation in multi-station compliant assembly based upon parametric space envelope (i.e. variation tool constructed from parametric curves). Three sources of variation: location-led positional variation, assembly deformation-induced variation and station transition caused variation are analyzed. Under proposal, geometric variations are modeled indirectly through a compact set of boundary control points. Compared with existing methods where geometric variation is modeled through targeting key feature points on the manufacturing part, the proposed approach brings modeling accuracy and computation efficiency. The effectiveness of the method is illustrated and verified through an industrial case study on a multi-station compliant panel assembly. The developed method provides industries a new way to manage geometric variation from compliant assembly.

Group gymnastics performance is an essential part of the opening ceremony of large-scale games. It can not only show the cultural heritage and scientific and technological achievements of a country and a nation, but also show their rich imagination and economic strength. The development of group gymnastics has injected new vitality into the progress of human civilization. As a social and cultural activity, it can not only make the audience feel the long history and culture of human beings, but also allow the audience to enjoy the visual beauty and make the audience feel refreshed. The research on the theory and training methods of group gymnastics formation and pattern change is an important link to speed up the faster and better development of group gymnastics. This paper studies the formation and pattern change methods of large-scale group gymnastics performances and the animation simulation method, classifies group gymnastics formations and patterns, and tries to apply wireless network communication technology to the training of group gymnastics formation and pattern changes. Provide an intuitive and easy-to-understand training method for group gymnastics training, so as to achieve the purpose of improving the efficiency of group gymnastics formation and pattern change training.
