内容摘要:

Topology optimization is a powerful structural design and modeling tool that is used in a wide range of applications. However, traditional subtractive manufacturing techniques make it difficult to fabricate complex structures designed by topology optimization. With the development of additive manufacturing technology, this challenge has been effectively solved, and further promoted the research and application of topology optimization. Since the traditional topology optimization methods tend to consider only the overall mechanical properties of the structure and ignore the stability of the designed structure during the manufacturing process, it is difficult to guarantee the performance of the final product. This presentation will first briefly introduce the mathematical model of topology optimization, and then focus on our team's recent work related to fabrication sequence optimization, which includes: 1) space-time topology optimization method and its application; 2) the thermal deformation minimization problem based on fabrication sequence optimization; 3) the thermal equation-driven space-time topology optimization method and its application, etc.
