Abstract
Topology optimization is at the phase of structural concept design and the result of it is foundation for succeeding design, therefore, structural topology optimization is more important to engineering design. in this thesis, in order to seek the optimal structure shape of the winch’s mounting bracket of ROV simulator, topology optimization design of it by finite element analysis software ANSYS was carried out. the results show that the topology optimization method is an effective optimization method and indicate that the method is correct and effective, it has a certain engineering application prospect.
Highlights
According to the type of design variables and degree of difficulty, the structural optimization of continuum structure can be divided into size optimization, shape optimization and topology optimization, corresponding to different stages of product design, namely the three stages of detailed design, basic design and concepts design
Compared to the first two optimizations, topology optimization can fundamentally change the structure of the object, the result is the basis of all the subsequent optimization of the design, so it has a great significance for engineering design; Though topology optimization has good prospects, it is recognized as the most difficult task in the field of structural optimization design
Structural topology optimization theory has been proposed for more than 100 years, and it is in recent decades that it has been in rapid development, with new theoretical and computational methods emerging, being applied in various fields of mechanical, of aerospace, marine engineering and shipbuilding, etc. the topology optimization of structure is one of the effective method for the precise design of the large parts [6]
Summary
According to the type of design variables and degree of difficulty, the structural optimization of continuum structure can be divided into size optimization, shape optimization and topology optimization, corresponding to different stages of product design, namely the three stages of detailed design, basic design and concepts design. We will use topology optimization module of ANSYS to optimize the design the winch’ mounting bracket of ROV simulator and achieve the improvement of the virtual design of the winch’ mounting bracket of ROV simulator, avoiding the design of blindness and improving the feasibility and effectiveness of the design, shortening the design cycle. We would verify the optimization results through the situation in real use. It provides an idea of simple principle taking advantage of topology optimization for design geometry element
