摘　　要：将数值流形方法应用到静电场的模拟分析中,推导出了基于流形方法的静电场单元刚度矩阵,处理了电场边界条件,建立了静电场模拟分析的数值流形格式,编制了电场分析模拟程序。对电热镦粗过程预热时工件内的电场电位分布进行了数值模拟,将结果与有限元软件分析结果进行比较,验证了流形方法在静电场分析中的合理性和正确性。Numerical manifold method was applied to analyze the electrostatic field. Numerical manifold formula of electrostatic field was derived. The boundary condition of the electrostatic field was disposed. Numerical manifold format of an electrostatic field simulation analysis was established. A program was scheduled to simulate the electrostatic field of the multi-physical fields of upsetting process. Comparing with the FEM method, the results show that numerical manifold method is rational and valid. This can provided a new calculating method for analyzing the electrostatic field of multi-physical fields.
