Abstract.Aiming at the problems of cracking and wrinkling in the forming process of floor beam, the design of the drawing die is finished, and the finite element analysis software DYNAFORM is used to analyze the drawing process of the floor beam, and the effects of blank holder force and drawbead on the formed part are analyzed. With the maximum thinning rate and maximum thickening rate as the evaluation index, the optimized process parameters are that blank holder force is F = 270kN and drawbead is set to segmented drawbead. The results have important reference value for the forming application of floor beam.

“…The engine hood is the most front-end opening and closing part of the body. Not only must it have the above functions, but sometimes it also needs to have the requirement to bear the weight of two people [3], so the study on the mechanical properties of the hood has essential value and significance.…”

With the development of machine learning and data mining, rapid design, rapid verification and rapid manufacturing have become the mainstream in the machinery industry. In this paper, the mapping function between the mechanical properties of the hood and its 11 dimensional parameters was mined using machine learning algorithms. By combining XGBoost and LightGBM algorithms with the bagging method, we proposed a hybrid model with hyperparameters optimized by the grey wolf algorithm. Subsequently, several machine learning models were trained and tested on a dataset of 6959 simulation samples, and the proposed hybrid model was found to have excellent predictive performance for the torsional stiffness ( R 2 of 0.9969 and root-mean-square error of 1.32185) and first-order modal frequency (0.9977 and 0.00989) of the hood. Moreover, the SHAP method (Shapley additive explanations) was used as a machine learning interpretation method to explain the predictive process of the mechanical performance. The results show that SHAP has great potential in model interpretation. This paper aims to develop a mathematical model of the mechanical properties of the hood, which can quickly predict the mechanical properties based on each key dimensional parameter. Therefore, engineers and designers can apply this approximate model in their design space exploration algorithms directly without training extra low-dimensional surrogate models.

Abstract. In view of the phenomenon that defects such as fracture, wrinkling and springback may generate when box shaped parts are stamped, however better surface quality on parts have been required. The process of drawing, cutting and springback for magnet covers with arc top and straight sidewall are simulated using the finite element analysis software Dynaform. The influences of binder force and die fillet radius on the stamping properties are studied by single factor analysis method, the stamping properties of parts under every condition are analyzed and reasonable process parameters are obtained by analyzing quality indexes of the maximum thinning rate, the maximum thickening rate and the amount of springback under every working condition.
