摘　　要：根据实际工作中的多股簧是两端并圈、且主要用作往复运动中的复进簧来承受冲击载荷的情况,推导了两端并圈多股簧的中心线数学模型,通过CATIA软件生成了两端并圈多股簧的三维几何模型;对几个关键加工工艺进行改进及设计参数的优化,使多股簧的力值达到设计指标的要求,直线度小于等于13 mm。进行了实际射击试验,验证了设计方案的正确性。Stranded wires helical springs of closed ends in practical work are used as return springs to bear the impact load.The centre line mathematical model of stranded wires helical springs of closed ends is presented at first.Then by using software CATIA,the three dimensional geometrical model of a stranded wires helical spring of closed ends is set up according to the centre line mathematical model.Through research of critical technology and optimization of design parameters,the force value of the springs meets the design requirements and the linearity is less than or equal to 13 mm.,It is successful in the actual shooting test.
