利用ANSYS分析软件对大型直线振动筛进行模态分析和时间历程响应分析，计算得出大型直线振动筛的7阶、8阶固有频率和其工作频率接近，容易产生共振，降低了振动筛的使用寿命。通过利用动画分析得到振动筛两侧板处在工作过程中的振动位移较大，因此，对振动筛加装加强肋，避免了共振的发生，同时也增强了侧板的强度。

Used ANSYS to analysis the modal and the time history response of large linear vibration screen,results show that large linear vibration screen 7,8 order natural frequency and working frequency was relatively close, it was easy to produce resonance, thereby reducded the work life of the vibration screen. Through used animation analysis showed that there was the larger vibration displacement at both sides of vibration screen, when it’s working,therefore, the vibration screen was additionally provided with reinforcing ribs, which not only avoided resonance, but also enhanced the strength of the side board.
