This research aims to model manual assembly processes by parameterizing operator force readings, specifically for engine and coolant hose connections in an automotive manufacturing line. During automotive assembly, many processes are still performed manually by the human operator due to the complexity of automating the process or product with current technology. Processes include completing hose connections and subsequent “push–pull–push” verification testing. Manual work introduces an opportunity for human error because of natural variation when completing tasks; even a slight inconsistency in operation can lead to an incomplete or missed process. These incomplete processes can pass post-production checks, such as a pressure test, but later loosen and fail, causing rework or warranty issues. To minimize human error, operator force is parameterized to provide real-time feedback to the connection status. The operator force was chosen to classify connections and to verify testing quantitatively. The parametrization was completed by partitioning the shear and normal forces using custom fixtures, with shear being the primary force type required by the process. The varying finger and hand engagement for the different connector locations were factored into the parametrization to encompass a broader range of manually completed tasks. It was found that operator forces in finger engagement for manual assembly could be effectively represented by a limited set of measurable parameters.

这项研究旨在通过参数化操作员的力读数来对手动装配过程进行建模，特别是针对汽车生产线中的发动机和冷却剂软管连接。在汽车组装过程中，由于使用当前技术自动化过程或产品的复杂性，许多操作仍由操作人员手动执行。过程包括完成软管连接以及随后的“推拉式”验证测试。手动工作由于完成任务时的自然变化而引入了人为错误的机会；甚至操作中的轻微不一致也可能导致过程不完整或遗漏。这些不完整的过程可以通过生产后检查，例如压力测试，但随后会松动并失败，从而导致返工或保修问题。为了尽量减少人为错误，通过对操作员的力量进行参数化设置，可以为连接状态提供实时反馈。选择了操作员力量来对连接进行分类并定量验证测试。参数化是通过使用定制夹具分配剪切力和法向力来完成的，其中剪切力是该过程所需的主要力类型。对于不同的连接器位置，手指和手的接合有所不同，已被参数化，以涵盖更广泛的手动完成任务。已经发现，可以通过有限的一组可测量参数来有效地表示用于手动组装的手指接合中的操作者力。参数化是通过使用定制夹具分配剪切力和法向力来完成的，其中剪切力是该过程所需的主要力类型。对于不同的连接器位置，手指和手的接合有所不同，已被参数化，以涵盖更广泛的手动完成任务。已经发现，可以通过有限的一组可测量参数来有效地表示用于手动组装的手指接合中的操作者力。参数化是通过使用定制夹具分配剪切力和法向力来完成的，其中剪切力是该过程所需的主要力类型。对于不同的连接器位置，手指和手的接合有所不同，已被参数化，以涵盖更广泛的手动完成任务。已经发现，可以通过有限的一组可测量参数来有效地表示用于手动组装的手指接合中的操作者力。
