Use Of Knowledge

Abstract This paper describes a system for parametric design and optimization of complex products. In the system, the use of knowledge-based and mathematical programming methods is combined. The motivation is that while knowledge-based methods are well suited for modeling products, they are insufficient when dealing with design problems that can be given an optimization formulation. This weakness was approached by including the information necessary for stating an optimization problem in the product models. A system optimization method can then be applied. The system also performs sensitivity analysis and has an interactive optimization module. The use of the system is illustrated by an example; the design and optimization of a two-speed gearbox.

Head Protection

Head impact with bonnet is one of the major causes for pedestrian severe injury or fatality in car accidents. This paper proposes a multidisciplinary design optimization method for bonnet inner based on pedestrian head protection along with bonnet stiffness requirement. A finite element (FE) model of a child headform impactor is developed and verified via simulation according to Global Technical Regulation No. 9 (GTR No. 9). Static stiffness analysis and headform collision simulation against one impact point for a particular bonnet are implemented. Parametric design and optimization analysis are carried out. Optimization solution significantly achieves a better head protection effect, which clearly affirms the feasibility of the proposed multidisciplinary optimization method and provides a reference approach to optimal design of engine bonnet inner.

Main Material

In order to improve the collision characteristics of energy-absorbing box and realize the optimization design, the collision simulation on energy-absorbing box is analyzed by LS-DYNA software. The collision characteristics including stress; strain; energy variation and deformation are analyzed for two kinds of main material; three different cross-sectional shapes and three different thicknesses in contrasts. Furthermore, energy-absorbing box has a smooth compression process effect through the improvement of structure. The simulation results may uncover the reasonability of the current design of energy-absorbing box and provide the basis for further improvement.

One main method of chip breaking is to use the grooves which can make chips be broken. 3D complex grooves meet the requirements of controllable chip breaking. It is too complicated to design 3D complex grooves using AutoCAD in short periods because each section of them is intricacy. Thus the author established the parametric model of the groove based on the advanced functions of Pro/Engineer, in which parameters can be obtained, transferred and modified through setting up parameter relations and compiling control programs. The combination of representative elements constituting the solid model of 3D complex grooves can be achieved by just inputting parameters, which can be directly transformed into 2D drawing accordingly; the heavy work of drawing complex surfaces using AutoCAD can be avoided; and the curvature of each normal profile of grooves are gotten. All such work lays a foundation for the groove design and optimization.

Integration of approximate model and clonal selection algorithm (CSA) is considered as an effective way to solve complicated optimization design problems in engineering field. The principles of approximate model and of clonal selection algorithm were presented in this paper. A variotherm temperature injection mold used to produce a large-size liquid crystal display (LCD) TV panel was demonstrated and an approximate model for optimizing the layout of heating channels of the mold was established. The clonal selection algorithm program was coded according to its principle in order to solve the established approximate model. The layout of the heating channels was optimized and the optimal solutions were obtained. Finite element simulation and industrial injection production indicated that the integration of the approximate model and clone selection algorithm used in this paper to optimize the layout of the heating channels for the injection mold was very effective.

This paper establishes a parametric model on the motor hanging seat structure by pro / ENGINEER software, and then optimizes the structure of the hanging seat by the weight of the hanging seat as the objective function. Taking into account the stress and displacement constraints in the optimization process, the weight of the hanging seat is greatly reduced after being optimized. It is practical significance to save a large amount of raw materials for the mass production and to reduce production costs and create higher economic efficiency.

An Enhanced version of the Salp Swarm Algorithm (SSA) referred to as (ESSA) is proposed in this paper for the optimization design of electromagnetic devices. The ESSA has the same structure as of the SSA with some modifications in order to enhance its performance for the optimization design of EMDs. In the ESSA, the leader salp does not move around the best position with a fraction of the distance between the lower and upper bounds as in the SAA; rather, a modified mechanism is used. The performance of the proposed algorithm is tested on the widely used Loney’s solenoid and TEAM Workshop Problem 22 design problems. The obtained results show that the proposed algorithm is much better than the initial one. Furthermore, a comparison with other well-known algorithms revealed that the proposed algorithm is very competitive for the optimization design of electromagnetic devices.
