| Abstract: | Spot weld layout design has great influence on mode,sinking stiffness and torsional stiffness of automotive doors.The door of one domestic car is taken as an example in this paper.The three-dimensional model is built by software CATIA and then meshed in the HyperMesh.The mode and stiffness analysis of three conditions is carried out using OptiStruct;then optimization of the spot weld layout of the door is performed by the topology optimization method provided by OptiStruct,and finally through the re-analysi... |
