A Study on the Lightweight Design of Hybrid Modular Carbody Structures Made of Sandwich Composites and Aluminum Extrusions Using Optimum Analysis Method

Aiming to the lightweight design of the long glass fiber reinforced thermoplastic (LGFT) composite wheel, this paper constructs the design process and the strength analysis method of long glass fiber reinforced thermoplastic wheel. First, the multi-objective topology optimization under multiple design spaces and multiple loading cases is conducted to obtain the robust structure, where the complicated ribs generated in design spaces are quite distinct from conventional steel or aluminum alloy wheel. The effects of weighting factors of two objectives and three loading cases on the topological results are discussed. And the long glass fiber reinforced thermoplastic wheel including the aluminum alloy insert is also designed in detail based on the concept structure and molding process. The novel metallic insert molded-in is another typical feature of long glass fiber reinforced thermoplastic wheel. Capturing the material anisotropy, the strength performances of long glass fiber reinforced thermoplastic wheel are simulated by using the finite element analysis method. The results show that there is a larger safety margin than the baseline wheel based on the maximum stress failure criterion. The long glass fiber reinforced thermoplastic wheel of 5.59 kg saves 22.3% weight compared to the aluminum alloy baseline. For the increasing requirement of automotive components lightweight design, the method and consideration in this paper may also provide some ways for the design and strength analysis of other carrying structures made of thermoplastic composite.

To adapt to the trend of lightweight of vehicles, and optimize the structure of vehicle components, the former overturned support of a medium-duty truck cab was optimized by lightweight design. The 3d model of the cabin former overturned support was firstly established, and then finite element analysis method was used to analyze the distributions of stress and displacement, with the support under extreme work conditions. And then a lightweight design was made basing on the analysis. The support blank is produced by permanent mold casting method. To meet the requirement of actual production, this paper, analyzed the casting defects of the structure by lightweight design, and then had a further modification basing on the actual casting technique. The results indicate that the weight of the cab support is reduced 23.2%, with lightweight design reducing the support weight effectively under safety. And the modifications of the structure casting performance meet better the structural optimization objective, and make the production of the cab support more efficient.

Maximum Separation

AbstractA series of simulated microstructures containing nanometer-scale precipitates was created with an atom probe simulator. These data were then analyzed with the proximity histogram and the maximum separation method to determine the influence of the particular analysis method. For simulated 2-nm-radius spherical precipitates, the optimized voxel size and delocalization were found to be 0.5-0.6 nm and 1.0-1.5 nm, respectively. Under optimum analysis parameters, the voxelization/delocalization process only slightly degrades the interface width determined from the proximity histogram to ˜0.15±0.04 nm.
