论文摘要
拓扑优化方法已在各个行业中广泛使用，因为它们的潜力提供了有前途的机械设备设计候选。但是，它们的应用通常仅限于由于在计算有效处理多个结构之间的触点和相互作用或通过常规使用的仿真技术方面进行触点和相互作用的难度而没有显着移动的对象。在本研究中，我们提出了一种用于包含材料点方法的对象的拓扑优化方法，该方法通常用于模拟计算机图形领域中对象的运动。几个数值实验证明了该方法的有效性和实用性。
Topology optimization methods have widely been used in various industries, owing to their potential for providing promising design candidates for mechanical devices. However, their applications are usually limited to the objects which do not move significantly due to the difficulty in computationally efficient handling of the contact and interactions among multiple structures or with boundaries by conventionally used simulation techniques. In the present study, we propose a topology optimization method for moving objects incorporating the material point method, which is often used to simulate the motion of objects in the field of computer graphics. Several numerical experiments demonstrate the effectiveness and the utility of the proposed method.
