Abstract

This article develops a bionic topology optimization method for engineering applications. Unlike traditional density-based methods, the real material density is used as a design variable, and its evolution is controlled by a simpler and improved bone remodelling formula. A calculation method of the threshold value in this formula is given that solves a problem difficult to define in engineering applications. A progressive function is constructed for solving the iterative fluctuation problem. A post-processing method based on the level set method is presented for the jagged boundary problem. Compared with the traditional bone remodelling algorithm, the proposed method has better optimization ability. Some examples prove the feasibility and effectiveness of the method. Moreover, the influence of some key parameters on the optimization is discussed. [ABSTRACT FROM AUTHOR]

Abstract

From the perspective of bionics, a structural topology optimization method combining a bone remodelling algorithm and real engineering requirements is proposed. Through joint simulation using MATLAB and Ansys, this method uses explicit physical concepts and efficient computer solving capabilities, which makes it highly practical and simple. The effectiveness and feasibility of the method are verified by comparing topology optimizations performed on four classical examples and the optimized results from the 99 lines of topology optimization code. Next, some key parameters of the method are discussed in depth, laying the foundation for a deeper understanding and application of the method. The purpose of this article is to introduce a bionic theory into the field of topology optimization by implementing an easy-to-use and extensible numerical algorithm to promote the development of this technology, so that it can better realize its engineering value.

Abstract

The solid modeling of special-shape spring is important to improve production efficiency of spring coiler. However, how to describe and represent its spatial shape is difficult because there is various special-shape spring with complex spatial shape. Consequently, the 3D modeling and visualization of special-shape spring is not easy to implement. The paper presents a solution to this problem. First, we extract four kinds of elementary shape feature and define their data structure respectively using feature technology. The special-shape spring may regarded as the combination of different elementary shape features. The dynamic linked lists are employed to record the position relation between them. Then, this article studies the 3D modeling methods of special-shape spring based on OpenGL. The emphasis is the discretization of the spring solid surface. Last, the high reality solid modeling is created with C++ Builder. [ABSTRACT FROM AUTHOR]
