Summary:-

Amphibious vehicles (AVs) are vehicles that can operate on both land and water. Historical evidence of different designs of amphibious vehicles shows that it lacked aesthetic and style aspects in its design. An effort has been made in this article to derive bio-inspired speed shapes considering aesthetic and dynamic characteristics to design the VA for amusement purposes. Aesthetics based on visual characteristics or expressions created in 2D and 3D drawing inspiration from biological organisms are called fast shapes. Quick Forms for AV are evaluated for user choices. A user survey was conducted to understand aesthetic preferences, perception of dynamism and their selection criteria.

A total of 22 users participated (age range: 18-35; 70% male, 30% female) in this study and they enjoy exploring AV for entertainment. Data were analyzed using SPSS software using descriptive and inferential statistics (Friedman ANOVA and Wilcoxon signed test). Speed ​​form 1 (inspired by the frog) was observed to be the most preferable among the three speed forms explored in this study. Speed ​​Form 1 was aesthetically better than the other Speed ​​Forms; however, all selected speed forms had dynamic characteristics. Therefore, the 1-speed form has the potential to be considered for the design of amphibious vehicles used for entertainment purposes.

Driving simulators are widely used in the automotive industry, government, military and academic research fields. This article provides an overview of the development of a kind of special amphibious vehicle driving simulator. A modularization structure has been developed according to the character of the structure, maintainability and space required for fixing, which provides a kind of practical methods to replace the failed device and effectively reduce the maintenance cycle of the simulator. .

A mixed PC-based network structure was developed and used to exchange information between the computers and the simulated cabin device. A special amphibious vehicle dynamics simulation model has been proposed for use on the driving simulator by adopting Matlab/Simulink Commercial-of-The-Shelf (COTS) product and Rapid Control Prototype (RCP) technology. The experiment results show that the amphibious vehicle driving simulator can provide the same performance as the real vehicle and effectively improve the driver’s driving skills.
