摘要
在基于弹性应变能相似方法的基础上,针对薄壁结构中主要焊接变形的模型预测,利用形状因子对几何条件加以放宽,从而大大便于模型的设计和研制,并降低成本。
On the basis of a similitude method, which is studied to predict welding distortion through the connection of elastic energy between real structure and model, a new coefficient called 'geometric factor' is proposed to simplify the manufacture of models. With the modified similitude method, the 'thin wall assumption' would be suitable for models which thickness of walls are not proportional to that of real structures. Thus, the new method is more convenient for prediction of welding distortion through models since the design and manufacture is dramatically simplified.
