采用有限元方法可以精确设计螺旋弹簧并进行优化,但这种方法对设计人员要求较高,弹簧的相关设计参数难以获得,有限元模型的建立和边界条件的定义非常困难。介绍等刚度和变刚度螺旋弹簧的特点。给出非线性弹簧计算工作流程和弹簧刚度计算模块。采用软件对汽车悬架弹簧参数进行计算,弹簧总圈数为8.48,有效工作圈数为7.13,材料直径为16.8 mm。运用Visual Basic语言编写"非线性螺旋弹簧设计、计算"软件,解决了复杂几何形状的非线性螺旋弹簧的设计参数求解问题。
Helical spring can be designed and optimized by adopting Finite Element Analysis, but the method needs higher requirement on designer, it is not easy to get the spring relevant design parameters, and it is difficult to establish Finite El ement Analysis model and define the boundary conditions. The characteristics of constant stiffness and variable stiffness hel ical spring were introduced. The nonlinear spring calculation work procedure and spring stiffness calculation module were given. The automobile suspension spring parameters were calculated with software, spring total coil number is 8.48, effec tive work coil number is 7.13, material diameter is 16.8 mm. The software of nonlinear helical spring design and calcula tion is written with Visual Basic language, the nonlinear helical spring design parameters solution problem of complicated geometry shape is solved.
