Pneumatic splice makes use of high-speed compressed air as the driving force to complete the yarn splicing, noticing that the change of the vent pressure has a significant effect on yarn splicing. This paper studies the impact of vent pressure on the quality of yarn splicing when twisting and untwisting. Modeling, analysis and simulation of the air splice is done with the integration of Pro/E and ANSYS software, to study the flow filed and obtain the influence on the speed and pressure of the inside the splicing chamber when changing the speed and pressure while keeping the diameter of splicing chamber diameter, the vent hole diameter and the relative angle are unchanged. The results of the analysis of the air splice will lay a solid foundation for the further optimized structure design.
In this paper, a cured door structure of mine rescue capsule is proposed, and compared with ordinary flat panel doors. Firstly two kind of three-dimensional solid models of mine removable protective airtight doors are established by the Pro/e software. And then take the advantage of the strength analysis of ANSYS finite element software to draw the stress and strain diagrams. The analysis results show that the strength and stiffness of the curved door is better than ordinary flat panel doors, which provide important theoretical basis and reference value on the design, research and dynamic analysis of the life-saving door.
At present, the mobile refuge chambers are mostly used square or circular structures. Based on these researches, a new chamber structure is presented in this paper, which is square and circular combined structure. The size and connection way are designed through the analysis of the working conditions and the requirements of the installation, transportation, maintenance and so on. Then the new structure is simplified to four kinds of cabin model, which can be analyzed by the ANSYS software. By the simulation analysis the reliability of the new structure is determined, which provides a theoretical basis for guiding the structural design of the mobile refuge chamber.
A kind of force measurement mechanism which can measure the two-directional transient impact load in the same time is introduced in this paper, and the analysis research of the mechanical part are followed. First, by using the pro/E software, the 3D concrete model of the force mechanism is contributed. Then, by means of the ANSYS finite element analysis software, its stiffness and strength are analyzed, and strain and deformation figures from different directions are obtained. The static maximum deformation and strain of the force measurement mechanism and its key components, and also the whole distribution are showed in the analysis results. The weak parts of the force measurement mechanism and its key components are also showed in this paper, which can be helpful for the further improvement and following actual tests [.1]
In this paper, the key components of globular indexing cam mechanism are analyzed by using the ANSYS finite element analysis software to solve the distribution of stress and strain of Globular indexing institutions caused by resistance moment. It is more intuitive and appropriate than the ever research of the single individual modal analysis process, and more easy to grasp the analysis results accuracy. It provides more solid theoretical basis for the production and application of globular indexing mechanism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
