The objective of this paper aims at investigating the feasibility of new coil winders with a spatial RSPC mechanism by conducting kinematic simulation. First, the design requirements and design constraints are specified based on the kinematics characteristic of coil winders. Then, the (4, 4) kinematic chains are obtained by number synthesis, and the atlas of feasible chains is generated. After that, the atlas of specialized feasible chains is found. Finally, new designs are obtained through the particularization process. In addition, an illustrated example of the RSPC mechanismselected from the new designs is given, and its feasibility is verified by performing kinematic simulation using ADAMS software. The result shows that it can meet the motion requirement of coil winders.

The work aims to present a novel press system, and to investigate its feasibility by performing a kinematic study. Firstly, the new design is proposed, which is composed by a motor, a constant speed coupling, a gear reducer, a generalized Oldham coupling, and a slider-crank mechanism. Secondly, its structural sketch is drawn, and its kinematic dimensions are obtained by studying its motion geometry. Then, a design example is given for illustration. Moreover, the solid model of the design is established, and then the validity of the design is verified by kinematic simulation using ADAMS software. Finally, the effects of different link ratios on the output motion are examined by conducting a number of simulations. The results of simulations show that the new design can produce more flexible output motion than a mechanical press. In addition, it has the advantages of lower cost, high reliability, and lower energy consumption, compared to a servo press.

On the basis of the existing mechanism, we can induce the topological structure of the original mechanism. By using the number synthesis of mechanism, we can find the link assortment which can satisfy topological structure of the original mechanism. By using permutation, we can obtain the generalized kinematic chains. According to the special design constraints, after appointing each link and kinematic pair, we can gain all the suitable feasible specialized chains. Then making a converse reasoning based on the generalized principle, we will finally integrate the schematic diagram of mechanism suitable for our design purpose. Therefore, if we make a kinematic and a dynamic analysis on mechanism based on this, after structural designing, we can find a new mechanical device whose performance is up to or even superior to that of the original product.

On the basis of analyzing the topological structure of an original mechanism, it leads to the generalized kinematic chain meeting the same topological structure characteristics of the original mechanism in accordance with the generalized principle of mechanism, number synthesis of kinematic chain and compound hings. Allocation of ground links and performing links in the kinematic chain can get all feasible specialized kinematic chains while considering practical design constraints. In the final step, concrete schematic diagram of mechanism being restored from specialized kinematic chains leads to a series of new mechanism different from the original one. Designers ascertain appropriate new mechanism after selection and analysis.

Abstract. Analysis of a certain topological structure characteristics of clamping mechanism of injection machine, according to general principles, converts it into only containing Deputy General of the connecting rod and rotating chain.

Abstract This paper addresses instantaneous motion characteristics of wheeled vehicles systems on even and uneven terrain. A thorough kinematic geometric approach which utilizes screw system theory is used to investigate vehicle-terrain combinations as spatial mechanisms that possess multiple closed kinematic chains. It is shown that if the vehicle-terrain combination satisfies certain geometric conditions, for instance when the vehicle operates on even terrain, the system becomes singular or non-Kutzbachian — it possesses finite range mobility that is different from the one obtained using Kutzbach criterion. An application of this geometric approach to the study of rate kinematics of various classes of wheeled vehicles is also included. This approach provides an integrated framework to study the kinematic effects of varying the vehicle and/or terrain geometric parameters from their nominal values. In addition, design enhancements of existing vehicles are suggested using this approach. This kinematic study is closely related to the force distribution characteristics of wheeled vehicles which is the subject of the companion paper [SN96].

Epicyclic gear trains have been broadly applied in engineering practice. In this paper, kinematic chains (K.C.) with single-joint (S.J.) were applied to innovative synthesis of the epicyclic gear trains. The method of the innovative synthesis of the epicyclic gear trains was presented. Not only the epicyclic gear trains in common uses were obtained, but some new types of epicyclic gear trains that are got difficultly by means of conventional combination method were gained. Thereby, a new way has been offered for the innovative synthesis of the epicyclic gear trains, at the same time, a way has also been offered for practical application of some multi-link kinematic chains gained by using the theory of type-number synthesis of the K.C. with S.J.. Examples show that the method presented in this paper is right and feasible, and the method is efficient and practical for the innovative synthesis of the epicyclic gear trains.
