The invention relates to a method for improving the incremental forming simulation calculation efficiency. The method comprises the following steps: step 1, establishing a model; step 2, defining feature boundaries and defining model boundary conditions; 3, partitioning: partitioning the finite element model into a plurality of partitions and defining boundary conditions of the partitions; 4, defining the motion trails of the pressure heads, wherein each area independently corresponds to one pressure head; and 5, carrying out incremental forming of the part. According to the method, the finiteelement model is partitioned, and the plurality of pressure heads are defined to perform simulation calculation at the same time, so that the simulation calculation efficiency is improved, and the product development period and the process verification period of incremental forming are further shortened. 本发明涉及一种提高渐进成形仿真计算效率的方法，该方法包括以下步骤：步骤一、建立模型，步骤二、定义特征边界，定义模型边界条件；步骤三、分区，将有限元模型划分成多个分区并定义分区的边界条件；步骤四、定义压头的运动轨迹，每个区均单独对应一个压
