Purpose

Virtual maintenance simulation is of great importance to help designers find and avoid design problems. During its simulation phase, besides the high precision requirement, collision detection must be suitable for all irregular objects in a virtual maintenance environment. Therefore, in this paper, a collision detection approach is proposed based on encapsulation for irregular objects in the virtual maintenance environment.

Design/methodology/approach

First, virtual maintenance simulation characteristics and several commonly used bounding boxes methods are analyzed, which motivates the application of encapsulation theory. Based on these, three different encapsulation methods are oriented to the needs of simulation, including encapsulation of rigid maintenance objects, flexible maintenance objects and maintenance personnel. In addition, to detecting collisions accurately, this paper divides the detection process into two stages. That is, in the first stage, a rough detection is carried out and then a tiny slice space is constructed to generate corresponding capsule groups, which will be redetected in the secondary stage. At last, several case studies are applied to illustrate the performance of the methodology.

Findings

The automatic construction algorithm for bounding boxes can be adapted to all forms of objects. The number of detection primitives are greatly reduced. It introduces the reachable space of the human body in maintainability as the collision search area.

Originality/value

The advantages of virtual maintenance simulation could also be advantageous in the industry with further studies. The paper believes this study is of particular interest to the readers of your journal.

虚拟维修中基于胶囊的不规则物体碰撞检测方法

目的

虚拟维护仿真对于帮助设计人员发现并避免设计问题非常重要。在仿真阶段，除了对精度的要求外，碰撞检测还必须适用于虚拟维护环境中的所有不规则物体。因此，本文提出了一种基于封装的虚拟维护环境中不规则物体的碰撞检测方法。

设计/方法/方法

首先，分析了虚拟维护的仿真特性和几种常用的边界框方法，这激发了封装理论的应用。基于这些，三种不同的封装方法针对仿真需求，包括刚性维护对象，灵活维护对象和维护人员的封装。此外，为了准确地检测碰撞，本文将检测过程分为两个阶段。即，在第一阶段中，执行粗略检测，然后构建微小的切片空间以生成相应的胶囊组，该胶囊组将在第二阶段中重新检测。最后，通过几个案例研究来说明该方法的性能。

发现

边界框的自动构造算法可以适用于所有形式的对象。检测原语的数量大大减少。它以可维护性的形式将人体可到达的空间引入碰撞搜索区域。
