Lastly, the process of water entry/exit of the amphibious vehicle was studied using Bonjean Scale. Furthermore, different loading cases were taken into consideration for an equilibrium analysis. In addition, the flooding points of the amphibious vehicle were set. Then, in order to study stability, the model was imported to a naval-friendly software and the curves of stability were obtained. Besides, StabPRS allows to perform calculations for. First of all, a lot of measurement had to be done in order to design 2D sketches, which eventually, will lead to a 3D model of a chosen amphibious vehicle with special purpose, which resembles the one used in reality. By entering variable data, we can obtain an updated assessment of the selected safety related parameters. The scientific aim of this paper is to study the stability of an amphibious vehicle with special purpose through the means of computer-aided-design (CAD) applications software. For studying and experimentally testing special purpose amphibious vehicles, it is preferable to use software programs, in order to reduce costs and to have a proper look on how a vehicle will work in reality and to avoid the risks of carrying out tests in open water. As the automotive industry is in continuos change, moving from a mechanical to a software-intensive industry, an essential part of the development and research process is represented by the computerized modelling and simulation since, this mechanism, provides prediction on how a vehicle will behave in real life situations. The calculators are available on the link below, as well as on the sub-page Research and Development, the bookmark Calculators. PRS also offers its own calculators which can be useful for ship design, construction, operation and repairs. In case of any difficulties, please contact PRS Research and Development Division for further information. Select a module relating to a problem which interests you. The displayed audiovisual demo version shows how the program operates in particular modules for a randomly configured multipurpose ship. Besides, StabPRS allows to perform calculations for visualization of intact ship’s movement in waves. By entering variable data, we can obtain an updated assessment of the selected safety related parameters. Tailored to a given ship’s parameters, StabPRS supports the day to day ship operation by providing quick calculation of the cargo mass change as handled, stability and general strength in any loading condition in both intact and damage conditions. PRS offers the development of the StabPRS program suited for a specified ship, to measure its particulars. StabPRS for control of ship loading conditions to show compliance with stability, longitudinal and local strength requirements is one of such programs. One of the objectives of the R&D work conducted in PRS is to elaborate numerical models and computer programs to analyse and simulate ship behaviour, its structure and equipment in normal and extreme service conditions.
