Abstract Owing to the existence of the cone angle, the size of a conical counter-rotating twin screw continuously changes along the axis, so it is not easy to model using SolidWorks. In this study, the parametric design of the modeling process is completed based on the Visual Basic language and a program-driven method. Finally, the SolidWorks program plug-in and user interface are developed to complete the automatic generation of the three-dimensional model of a conical counter-rotating twin screw.

Abstract This paper gives an overview of a collaborative design system (CDS) for electromechanical products. To reduce design costs and to manufacture high-quality products, it is well known that concurrent engineering (CE) is a very efficient approach. Three-dimensional (3D) CAD system and engineering database system are essential components of CE. The CDS is an environment to realize CE. By creating 3D models in a computer and performing some simulations such as mechanical, electronic, software simulation and integrated simulations, it is possible to estimate functions, assemblability, manufacturability and so on, before making prototype models. In this paper, we outline the CDS and mainly discuss the total information management system (TIMS) which makes an important role of the CDS. This paper describes the implementation experience of some functions of the TIMS.

Planetary Gear Sets

Planet-to-planet load sharing is a major design and manufacturing tolerancing issue in planetary gear sets. Planetary gear sets are advantageous over their countershaft alternatives in many aspects, provided that each planet branch carries a reasonable, preferably equal, share of the torque transmitted. In practice, the load shared among the planets is typically not equal due to the presence of various manufacturing errors. This study aims at enhancing the models for planet load sharing through a three-dimensional formulation of N-planet helical planetary gear sets. Apart from previous models, the proposed model employs a gear mesh load distribution model to capture load and time dependency of the gear meshes iteratively. It includes all three types of manufacturing errors, namely constant errors such as planet pinhole position errors and pinhole diameter errors, constant but assembly dependent errors such as nominal planet tooth thickness errors, planet bore diameter errors, and rotation and assembly dependent errors such as gear eccentricities and run-outs. At the end, the model is used to show combined influence of these errors on planet load sharing to aid designers on how to account for manufacturing tolerances in the design of the gears of a planetary gear set.

Electrical Cables

The concept and project of umbilical cables and flexible pipes are not simple tasks, due to the great variety of components and possible arrangements. The design of those elements is based on the functions they are intended to perform. Also, some structural characteristics determine which component will be selected, including electrical cables and hydraulic hoses, to control underwater equipment, protective sheaths, helically wounded tensile armors, anti-wear layers, interlocked carcasses; pressure armors and so on. The modeling process consists on defining the cable features and selecting the elements that will compose it. The process should take into account the desired structural characteristics, such as axial stiffness, and must respect some constraints, such as weight. To have an operational cable, one must follow a number of steps from definition to validation of the cable and any tool that provides a easier way to deal with this process is highly desired. In this scenario, Computer Aided Design software was conceived. It enables the definition of cable elements and set its relative arrangements in a cross-section view. Post-processing features are also part of the program, enabling users to visualize the geometry, determining possible interferences only visible in a three-dimensional visualization module. Although a solver is also available to determine stress and displacements and, as a sub-product, the cable weight and equivalent stiffness, the CAD software can be easily integrated to other solvers, to provide pre and post processing resources. This paper gives a general description of the whole CAD system but focus on the three-dimensional module. Through the paper, an overview of the software is shown, pointing out the system requirements. Next, the user interface is described, showing its features and, to conclude, modeled cables geometries and some results are shown.

Hydraulic Retarder

In order to optimize the design method and improve the performance of hydraulic retarder, the numerical simulation of multi-field coupling of heat, fluid and solid is carried out to hydraulic retarder, based on the numerical computation and algorithm of heat-fluid coupling and fluid-solid coupling. The computation models of heat-fluid coupling and fluid-solid coupling of hydraulic retarder are created. The three dimensional model of hydraulic retarder is established based on CATIA software, and the whole flow passage model of hydraulic retarder is extracted on the basis of the three dimensional model established. Based on the CFD calculation and the finite element numerical simulation, the temperature field, stress field, deformation and stress state are analysised to hydraulic retarder in the state of whole filling when the rotate speed is 1600 r/min. In consideration of rotating centrifugal force, thermal stress and air exciting vibration force of blade surface, by using the sequential coupling method, the flow field characteristics of hydraulic retarder and dynamic characteristics of blade structure are analysised and researched based on multi-field coupling of heat, fluid and solid. These provide the theoretical foundation and references for parametric design of hydraulic retarder.
