传统的计算机辅助设计(CAD)和计算机辅助装配规划(CAAP)系统由于没有考虑人类的经验和知识获取来直观地支持装配规划，所以仍然存在局限性。此外，在装配评价中没有考虑质量检测、车间布局、人体工效学和物理约束等方面的因素。虚拟现实(VR)系统可用于模拟、分析和优化包括装配在内的制造过程。虚拟现实(VR)和触觉系统的使用可以提高装配工艺规划、评估和训练的效率，本文描述了一种用于真实装配任务装配训练的触觉辅助虚拟现实系统的实验。评估中考虑了三组不同训练水平的个人。第一组接受了虚拟现实系统的培训，包括触觉反馈。第二组也接受了同样的虚拟训练，但没有触觉反馈。第三组没有在虚拟环境中接受任何培训。训练结束后，通过构建真实的装配任务来评估三个不同组的装配性能。结果表明，与没有接受培训的人相比，接受了带有力反馈的虚拟培训的人的装配性能有了显著的提高。版权所有©2014由ASME
Traditional computer aided design (CAD) and computer aided assembly planning (CAAP) systems are still limited because they do not consider human experience and knowledge capture to support intuitively the assembly planning. Moreover, some aspects such as quality testing, shop floor layout, human ergonomics and physical constraints are not considered during the assembly evaluation. Virtual reality (VR) systems can be used to simulate, analyze and optimize manufacturing processes including assembly. The use of (VR) and haptic systems can improve the efficiency of assembly process planning, evaluation and training.This paper describes an experiment conducted to investigate the benefits of a haptic aided virtual reality system for assembly training of real assembly tasks. Three groups of individuals with different level of training were considered in the evaluation. The first group received training by the virtual reality system including haptic feedback. The second group also received the same virtual training but without haptic feedback. The third group received no training in the virtual environment. Upon completion of the training, the assembly performance of the three different groups was evaluated by the construction of a real assembly task. The results have shown a significant improvement in the assembly performance of individuals who undertook a virtual training with force feedback, compared with those who did not take training.Copyright © 2014 by ASME
