This study aims to present a new haptic-enabled virtual assembly system for the automatic generation and objective assessment of assembly plans. The system is intended to be used as an assembly planning tool along the product development process.,The generation of product assembly plans is based on the analysis of the assembly movements and operations performed by the user during the virtual assembly execution, and the objective assessment of product assembly is based on the definition and computation of new proposed assembly metrics.,To evaluate the system, a case study corresponding to the assembly of a mechanical component is presented and analyzed. The results demonstrate that the proposed system is an effective tool to plan and evaluate different product assembly strategies in a more practical and objective approach than existing assembly planning methods.,Although the virtual assembly execution time is larger than the real assembly execution time, the assembly planning and evaluation results provided by the system are valid. However, the development of higher performance collision detection algorithms is needed to reduce the simulation time.,The proposed virtual assembly system is able to not only simulate and automatically generate assembly plans but also objectively assess them from the virtual assembly task execution. The introduction and use of several assembly performance metrics to objectively evaluate assembly strategies in virtual assembly also represents a novel contribution.

支持触觉的产品装配虚拟规划和评估

本研究旨在提出一种新的支持触觉的虚拟装配系统，用于装配计划的自动生成和客观评估。该系统旨在用作产品开发过程中的装配规划工具。产品装配计划的生成基于对用户在虚拟装配执行期间执行的装配运动和操作的分析，以及客观评估产品装配的定义和计算是基于新提出的装配指标的定义和计算。为了评估系统，提出并分析了一个与机械部件装配相对应的案例研究。结果表明，与现有装配规划方法相比，所提出的系统是规划和评估不同产品装配策略的有效工具。虽然虚拟装配执行时间大于实际装配执行时间，但装配系统提供的规划和评估结果是有效的。然而，需要开发更高性能的碰撞检测算法来减少仿真时间。所提出的虚拟装配系统不仅能够仿真和自动生成装配计划，而且能够从虚拟装配任务执行中客观地评估它们。引入和使用几种装配性能指标来客观评估虚拟装配中的装配策略也代表了一种新的贡献。
