The invention relates to an optimization method of a large tube bundle unit bracket. The optimization method comprises the following steps: establishing a finite element analysis model of the tube bundle unit bracket by adopting PATRAN stress calculation and analysis software; in the finite element analysis model of the tube bundle unit bracket, loading constraint, applying a load working condition, and considering 1.2 times of safety coefficient; analyzing the maximum resultant stress, shear and limit displacement of the tube bundle unit bracket through PATRAN software, optimizing and improving the point positions with insufficient strength according to the analysis result, and then analyzing until the standard requirements are met; according to a checking result, a support modification guide manual is given; and according to the instruction manual, a tube bundle unit support design drawing is modified. The structure of the tube bundle unit support can be simplified, materials are saved, meanwhile, the overall strength of the tube bundle unit support is ensured, in the design process, technicians have the basis for design and model selection of the large tube bundle unit support, the design and model selection are more reasonable and accurate, and the ship building quality is improved.
