Open architecture products are built with the platform and open interfaces where different add-on modules from various sources can be connected to meet individualized customers’ requirements. Since add-on modules from different vendors are interacted with the product platform through the interfaces, enhancing the interface adaptability to facilitate interactions between the platform and add-on modules is critical for the development of open architecture products. In this work, an approach of open interface modeling is proposed based on parts and their assembling relationships. The quantification of the open interface is introduced with functional, structural, manufacturing, and operational adaptabilities. The developed analytical approach can enhance the interface adaptability of open architecture products. An example is provided to demonstrate the effectiveness of the developed method. © 2017 Springer-Verlag London Ltd.

This paper presents an elastodynamic characteristics comparison of the 8-PSS redundant parallel manipulator and its non-redundant counterpart-the 6-PSS parallel manipulator through simulation. The natural frequency and the displacement response of the moving platform are investigated, respectively. It is shown that the natural frequency of the 8-PSS redundant parallel manipulator is higher than that of the 6-PSS parallel manipulator while its displacement responses of the moving platform are smaller than those of the 6-PSS parallel manipulator. © 2009 Elsevier Ltd.

The evaluation of joint velocity, torque, and power capability of the 8-PSS redundant parallel manipulator is investigated in this paper. A series of new joint capability indices with obvious physical meanings are presented. The torque index used to evaluate the respective joint dynamic capability of the redundant parallel manipulator is decoupled into the acceleration, velocity, and gravity term. With these velocity, torque, and power indices, it is possible to control the respective joint capability of the redundant parallel manipulator in different directions. The indices have been applied to evaluate the joint capability of the redundant parallel manipulator by simulation. They are general and can be used for other types of parallel manipulators. © 2010 Cambridge University Press.

Pseudo solder is one kind of familiar solder joint defect, and it is very difficult to be detected in surface mounted technology. Reduce the pseudo solder is viewed as one of effectively way to keep the quality of solder joints. In this manuscript, the quality of component, solder paste printing process, mounting processing, reflowing process, solder material are analyzed to illustrate the cause of pseudo solder in surface mounted technology. Based on the five factors, a pseudo solder model is built for IC component. In the pseudo solder model, its parameters are used corresponding to the cause of pseudo solder, and their values are used to evaluate the degree of satisfaction based on the SMT technological process. Experiments results show that parameters of the pseudo solder model can illustrate the cause of pseudo solder effectively.

The precision model of the 5-axis CNC machine tool can be built up based on the theory of kinematics for multi-body system (MBS). And then based on the precision model, the sensitivity analysis established with matrix differential is a method of identifying geometric error parameters for machine tool. And the geometric error factors of major parts that have relatively significant influence on comprehensive spatial error of the machine tool are identified. Finally, important theoretical basis for improving the titanium alloy Five-axis CNC machining center reasonably and for the error compensation can be provided. © (2013) Trans Tech Publications, Switzerland.

Robust design (RD) is an important method because it can reduce the variation of products or processes and improve their performances such as static and dynamic quality characteristics at a low cost. In order to obtain an efficient and universal RD solution, a novel analytical RD methodology is proposed based on axiomatic design principles. The covariance matrix of multiple functional requirements (FRs) that can reflect dependency relationship is obtained via the Talyor series expansion. Evaluation mechanism based on information axiom is introduced to select the better design scheme gained with different robust optimization models. The distinct characteristics of the proposed method are the implementation by matrix differential, and the ability that can deal with multiple FR optimization simultaneously. An RD optimization of a fi ve roller coating head is illustrated. The results show that the proposed method can optimize the design parameters which meet the multiple FRs.

In this paper, the single-side asymmetry cycloid-pin-tooth arc rotor of compressor is studied. It analyses the Curve equation of single-side asymmetry cycloid-pin-tooth arc rotor of compressor. Meanwhile it carries on the parametric designs of the single-side asymmetry cycloid- pin-tooth arc rotor of compressor under Visual C++ development environment. The parametric modeling for rotor is implemented by Pro/e and the application program is written by Pro/TOOLKIT at the same time. The new model of compressor rotor is regenerated through inputting main parameters directly in man-machine conversation dialog box. Thus it can improve design efficiency of compressor rotor, and it will shorten the development cycle of production and reduce the designer's repeated work. ©2010 IEEE.

Aiming at spring in pre-positioned fixture of shaft pressing and assembling machine subjected to alternating load and impact load, high working frequency and easy to fatigue failure, to guarantee spring service life and make the fixture more application scope, a multi-objective optimal math model had been established in this paper. In the model, spring's basic structural parameters are used as design variables; strength, stiffness, and spring index and so on are used as constraint conditions; spring fatigue strength safety factor and volume are used as objective functions. And the model had been solved by using the unified objective function method and LINGO software. The example operation result shows that optimal spring volume is smaller than one of traditional design. And design purpose has been realized. © (2013) Trans Tech Publications, Switzerland.

The research of the control system of automatic feeding machine in the present paper can be applied in different mechanical designs - from simple key-press input of cycling days, multiple time intervals and the feeding amount to setting steps of numbers of stepping motor via the control of SMC by time setting. This not only realizes the objective of "fixed-time" and "fixed-quantity" feeding, but also solves the problems of serious leaking, high failure rate, and loud noises during the process of using warehouse-type feeding machines, which brings favorable economic and social benefits for enterprises. © (2012) Trans Tech Publications, Switzerland.
