In order to manage the complex simulation data management in the process of mechanical dynamics simulation, a new management model was presented which is Performance Simulation Model(PSM). The model was based on PDM product structure and the concepts and elements of PSM were defined in this paper. Furthermore, the functional framework of PSM was proposed which based on the hierarchical relationship of product structure and the data stream relationship of data structure matrix. Finally, PSM was applied on ship planetary reducer collaborative simulation platform. The result indicates that the simulation data in mechanical collaborative simulation are managed by PSM, and the problem of interaction between collaborative simulation and PDM is solved.

The provision for producers to update base acres and payment yields in the 2002 farm bill afforded an opportunity to test whether it was feasible to deliver a complex simulation model directly to producers. A Monte Carlo simulation model for assessing the economic impacts of the alternative base and yield options on individual farms was developed and made available to producers via the World Wide Web. The experiences and challenges from this collaborative extension and research effort are described, as well as the issues educators might consider before delivering complex software to a national audience via the Web.

Using computers to conduct human body simulation experiments (e.g., human sport simulation, human physiology simulation, and human clothing simulation) can benefit from both economic and security. However, the human simulation experiment usually requires vast computational resources due to the complex simulation model which combines complicated mathematical and physical principles. As a result, the simulation process is usually time-consuming and simulation efficiency is low. One solution to address the issue of simulation efficiency is to improve the computing performance of the server when the complexity of the simulation model is determined. In this paper, we proposed a concurrent optimization scheme for the server that runs simulation experiments. Specifically, we firstly propose the architecture of the server cluster for the human body simulation, and then we design the concurrent optimization scheme for the server cluster by using Nginx. The experiment results show that the proposed concurrent optimization scheme can make better use of server resources and improve the simulation efficiency in the case of human sport simulation.

The paper is aimed at the calculation of the throwing parabola of material particle and its graphical interpretation by changing input parameters selected according to predefined requirements. The aim is to compile a complex simulation model and comparison of the obtained simulation results on the model with analytical calculation. Simulation experiments on the model confirmed the known dependence of the change of throwing parabola by increased speed and retention of the radius of the staging drum. The simulation model was created in the program MSC Adams/View – a tool for easy construction and visualization of the model and convenient evaluation of the obtained results.

ABSTRACT Complex simulation systems are often used in order to enhance the safety level on newly designed navigation areas and to facilitate their verification process. The application of these systems supersedes older methods based on manoeuvring basins, wherein models minified in particular scales were used. Modern methods are definitely cheaper and require less work. The paper presents the method of assessment of the compatibility of a ship simulation model with its real counterpart. Access to the simulator’s components responsible for creating and editing bodies of water as well as ship models gives the possibility of their verification. Using cutting-edge navigation systems such as inertial systems, weather stations and GPS gives the possibility of obtaining indispensable information about ship’s behaviour under certain hydro-meteorological conditions.
