摘要
从碟簧的实际结构特征和具体工作特点出发,对组合碟簧进行静刚度试验测试,并利用有限元软件ANSYS/LS—DYNA的非线性显式算法进行计算,对叠合碟簧的连续加载以及加载—卸载过程进行数值模拟,得到碟簧的载荷位移关系曲线.将结果和试验值与传统的计算法Almen-Laszlo公式的结果进行比较,可以看出这种方法计算的结果与试验值基本符合,比Almen-Laszlo公式准确.从而为在工程应用中选择组合碟簧提供一个简便正确的方法.
Based on the actual structure and specific working character of disk spring,experimentation was done on combination disk spring and the process of continuous load as well as load—unload of congruent disk spring was imitated with nonlinear explicit algorithm of the finite element software ANSYS/LS—DYNA. Therefore,we can obtain the result of the relative curve of load—displacement.The result was contrasted with experimented value and traditional algorithm Almen—Laszlo formula.The conclusion can be drawn that ...
