| Abstract: | A fatigue reliability analysis of the structure of the steel group spring, which is the key part of a type of electromagnetic vibr ator, is studied. Considering the randomicity of the material and the shape dime nsion, an optimal mathematical model is built which is based on the design varia ble of the spring number and its shape dimension, the object function of the tot al volume of spring group or the piece minimum, satisfying the spring group fati gue reliability, stiff, the upper limit and the lower limit of design variable. The optimal method has been applied to four design schemes with good results. |
