| 目的 为了减轻和缓解用户物理负担和心理负担，对康护辅具进行轻量化设计，探索一种产品形态轻量化与结构轻量化并行的综合设计方法。方法 以保护靴为例，将轻量化意象作为形态设计目标，采用语义差法和主成分分析得到轻量化意象及其典型代表样本;采用视觉动力形式分析建立产品形态轻量化意象的映射关系，并在此关系上通过曲线控制法进行初始形态方案设计;利用SolidWorks软件进行拓扑优化，判断材料冗余部分，为结构减重提供指导;再次结合映射关系对初始形态进行形态优化设计，得到最终设计方案。结论 对保护靴设计方案进行评估，仿真结果显示方案重量降低近40%，评价结果显示轻量化意象评价良好，表明了该方法的可行性，为康护辅具的轻量化设计提供了新思路与方法。 |

| Abstract: |
| The work aims to conduct lightweight design of health care assistive devices and explore a comprehensive design method of product form lightweight and structure lightweight to reduce and alleviate the physical and psychological burdens of users. With protective boots as an example, firstly, the lightweight imagery was taken as the form design target, and the semantic difference method and principal component analysis were used to obtain the lightweight imagery and its typical representative samples; secondly, the visual dynamic form analysis was used to establish the mapping relationship of the lightweight imagery of the product form, and the initial form scheme was designed by the curve control method based on this relationship; then SolidWorks software was used to optimize the topology, determine the redundant part of material and provide guidance for structure weight reduction; finally, the mapping relationship was combined again to optimize the initial form design and obtain the final design scheme. The protective boot design scheme is evaluated. The simulation results show that the weight of the scheme is reduced by nearly 40%. The evaluation results show that the lightweight imagery is well evaluated, which shows the feasibility of the method and provides a new idea and method for the lightweight design of health care assistive devices. |
