The invention discloses a modal frequency avoiding method based on a mass discretization model, computer equipment and a computer readable storage medium. The method comprises the following steps: partitioning a modifiable region of a structural part based on the mass discretization model, so as to obtain a plurality of modifiable blocks; according to the thickness of each modifiable block, obtaining the modal frequency value of each order of each modifiable block; and according to the modal frequency values of all orders of the multiple modifiable blocks, determining the optimal thickness of the modifiable blocks to perform frequency avoidance, thereby performing design through the optimal thickness of the modifiable blocks to realize frequency avoidance. 本申请公开了一种基于质量离散化模型的模态避频方法、计算机设备及计算机可读存储介质，该方法包括：通过基于质量离散化模型对结构件的可修改区域进行分块，以获取多块可修改块；根据设置各个所述可修改块的厚度，以获取各个所述可修改块的各阶模态频率值；根据多个所述可修改块的各阶模态频率值，确定所述可修改块的最优厚度以进行避频，从而通过可修改块的最优厚度进行设计实现避频。
