The invention relates to a lightweight optimization method for an automobile frame. The method includes the following steps: according to preset modeling parameters, solid modeling is performed on the automobile frame to obtain a frame entity model; according to the preset torsion Rigidity boundary conditions, perform topology optimization analysis on the frame entity model to determine the optimization area corresponding to the frame middle beam in the vehicle frame, and perform structural optimization on the frame middle beam; according to the vehicle frame Based on the shell mesh model established by the solid model of the frame and the preset bending boundary conditions, the dimensions of the main beams on opposite sides of the vehicle frame are optimized to obtain the optimal section size and material thickness. The lightweight optimization method for the vehicle frame proposed by the invention can ensure the overall torsional rigidity and bending rigidity of the vehicle frame, and further improves the product quality.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for optimizing the weight of an automobile frame. Background technique [0002] With the increasing requirements of the country for energy saving and emission reduction and the intensification of competition in the automobile industry, how to apply advanced structural design technology to the structural design of the automobile frame to realize the weight reduction and light weight of the frame, so as to meet the increasingly stringent regulations of the country Requiring and improving product competitiveness will become the key factor for the survival of automotive OEMs in the future. [0003] Platform-based development technology, that is, to achieve generalization and light weight as much as possible under the premise of meeting the performance bandwidth, so that various models such as SUV and MPV models have a large number of common body parts, thereby minimizing...
