摘　　要：以保证振动筛减振弹簧的疲劳安全系数,减小弹簧质量和提高弹簧自振频率为优化目标,建立以弹簧的丝径、中径和工作圈数为设计变量的多目标优化数学模型。通过在Ma tla b软件中编写优化设计程序并进行求解,得出多目标优化函数的有效解。最后圆整得到弹簧的最终结构参数并对其约束条件进行验算,结果证明按照此方法得到的设计变量值能够满足振动筛减振弹簧多目标优化设计的要求。For a vibratory screen an optimal target was set for sure fatigue safety factor, lesser spring mass, and higher spring natural frequency of vibration to build mathematic models of multi target opti-mization for the spring minimal diame-ter, medium diameter, and number of ef-fective coils. A way out is to compose an optimal design program for solution in a Matlab software to have got effective so-lutions to multi target optimal functions. Finally, there have been gotten final as-sembly data completely for the springbefore checking their restraints. Results prove that variable values for design can satisfy requirements for designing such a sieve according to the process.
