特种碟簧的变形研究

Research on Deformation of Special Disk Spring

对一种外面包有橡胶模的特种碟簧的变形进行了研究。对特种叠合碟簧进行试验测试,将测试结果和普通碟簧的试验结果进行比较,发现了橡胶膜对碟簧变形的影响程度。用有限元软件LS-DYNA对特种碟簧的非线性变形进行数值模拟,得到特种碟簧的载荷变形关系曲线,将结果和试验值进行比较,看出这种方法计算的结果和试验值基本符合。

Deformation of a kind of special disk spring that is wrapped with rubber membrane outside was studied. Effect of deformation of combination disk spring by rubber membrane is discovered, through doing experiment to special disk spring and comparing result with result of experiment of general disk spring. Furthermore, numerical simulation is done to nonlinear deformation of special disk spring by finite element software ANSYS/LS-DYNA, and load-deformation curve of special disk spring was get. The result is compared with experimented value, and conclusion can be drawn thatresult approximately agrees with experimental value.
