剥线钳是一种用于剥去电线绝缘皮的手持工具。现有的剥线钳结构复杂、成本高、容易磨损。考虑到剥线钳在运动过程中自由度会发生变化，将变胞变换的思想引入剥线钳的设计中，基于柔顺五杆机构得到一种新型的柔顺剥线机构。利用伪刚体模型法对柔顺剥线钳的不同工作状态进行建模，给出了相应的运动静力学模型；根据剥线钳的设计要求建立优化目标函数，并采用粒子群算法完成了优化设计。参照优化结果加工的样机对不同规格的电线进行剥线测试，证实该新型柔顺剥线钳具有较好的剥线效果，可大幅降低现有剥线钳的成本，便携且具有结构简单、工作可靠等优点。

Awire stripper is a hand-held device used to strip the electrical insulation electric wires. The existing wire strippers are complicated, costly and easy to wear. Considering that wire strippers change their degrees-of-freedom during their motion, a new stripper design based on a compliant 5-bar mechanism utilizing metamorphic transformation is presented for wire stripping. The pseudo-rigid-body method (RPBM) is applied to solve the kinetostatic behaviors of the mechanism in different working phases. The objective function is established for optimizing the design and an optimal design is obtained using a particle swarm optimizer (PSO). Finally, based on the optimization results, a prototype is fabricated, which shows good performances in wire stripping. This compliant wire stripper is low cost, portable, simple in structure and reliable.
