摘　　要：柔性铰链设计依赖于预期使用要求、塑料材料及注射加工过程,为此探讨了完全弹性、完全塑性、弹塑性柔性铰链几何设计的理论公式,分析了注射加工对柔性铰链弯曲寿命的影响。通过实际案例,采用模流分析软件预测了注射加工中不同模具设计对柔性铰链弯曲寿命的影响。The design of flexure hinges depends on its expected application requirements,plastic materials and injection molding process.In this paper,a theoretical formula for the geometric design of three kinds of flexure hinges including complete elastic hinge,full plastic hinge and elastic-plastic hinge was discussed;and the influence of injection molding on the flex life of flexure hinges was analyzed.Based on actual cases,the effect of different injection mould design on the flex life of flexure hinges was predicted by CAE analysis software.
