Configuration Design and Aerodynamic Analysis of Long-endurance Hydrogen Energy Hybrid Powered Unmanned Aerial Vehicle

To meet the design requirements of long-endurance hydrogen energy hybrid powered Unmanned Aerial Vehicle, the combined MATLAB and XFOIL optimization methods, based on the optimized airfoil, were used to optimize the design of the airfoil of HM114. Two aerodynamic layouts for straight wing and elliptical wing (HY1) were designed. Computational fluid dynamics was adopted to analyze the aerodynamic performance of the two layouts. The results show that the lift coefficient of the optimized airfoil is...

Corrugated Rolling Simulation and Deformation Behavior Analysis of Cu/Al Composite Plate

In order to explore the stress-strain characteristics and microstructure evolution of Cu/Al composite plate during corrugated rolling, a three-dimensional finite element model was established. The accuracy of the model was verified by rolling experiments. The compressive stress, shear stress, and equivalent strain at the characteristic position of rolling deformation zone were extracted and their distribution characteristics were analyzed. In addition, the morphology of the bonding interface and ...

Database Assessment of Design Methods for Axial Bearing Capacity of Driven Piles in Sand

The common design methods for axial bearing capacity of driven piles in sand include conventional API method and four CPT-based methods, namely ICP-05, UWA-05, Fugro-05, and NGI-05. However, the reliability and accuracy of these design methods are still unclear, mainly owning to the lack of high-quality static load test data that can be used to evaluate the performance of these methods. High-quality database is also useful in the verification of any new design method. A new ZJU-ICL sand database ...

Numerical Simulation and Experimental Verification of the Hysteretic Behavior of Song Style Timber Frame

Numerical simulation is widely used in the analysis of seismic performance of ancient timber structures, but the simulation analysis of an overall structure often lacks corresponding experimental verification, which leads to doubts about the authenticity of the results. A typical Song style beam-column-Dougong timber frame was taken as the research object. The deformation and hysteretic behavior of the structure under cyclic lateral loads were simulated and analyzed by using ABAQUS. The simulatio...

Analysis of Aerodynamic Effects of the Inter-stepwise Buffer Structure in High-speed Railway Tunnel

The aerodynamic problems caused by high-speed train passing through tunnel become more and more serious with the increase of train speed. In view of the existing line reconstruction which is limited by the terrain and can not be equipped with additional buffer structure in tunnel, we proposes a new type of inter-stepwise buffer structure. In this paper, the flow field between train and tunnel was modeled according to the k-ε two equation turbulence model, the information exchange was realized by...

Reinforcement Effect of Horizontal Bottom Sealing of Deep Foundation Pit in Water-rich and Deep Sand Layer

For deep foundation pit with rich water and deep sand layer, construction safety problems such as water and sand gushing may occur during excavation.Base sealing with well point dewatering is a common measure to ensure the safety of foundation pit excavation.This paper is based on an open-cut construction project of a metro station in Taiyuan. The fluid-structure coupling analysis and comparison of foundation pit excavation process were carried out by using finite element software.Combined with t...
