“…The rigid body dynamics solver computes the motions of bodies based on the NewtonEuler equations for both translational and rotational motions, in addition, joints and contacts are handled using relevant constraint/contact equations. Further details on equations and methods of solution can be found in the literature (Bender et al, 2012, Erleben et al, 2005. In order to create the geometry of gravels realistically, the Voronoi-based tessellation was used.…”

A physics engine is computer software which provides a simulation of certain physical systems, such as rigid body dynamics, soft body dynamics and fluid dynamics. Physics engines were firstly developed for using in animation and gaming industry; nevertheless, due to fast calculation speed they are attracting more and more attention from researchers of the engineering fields. Since physics engines are capable of performing fast calculations on multibody rigid dynamic systems, soil particles can be modeled as distinct rigid bodies. However, up to date, it is not clear to what extent they perform accurately in modeling soil behaviour from a geotechnical viewpoint. To investigate this, examples of pluviation and vibration-induced densification were simulated using the physics engine called Bullet physics library. In order to create soil samples, first, randomly shaped polyhedrons, representing gravels, were generated using the Voronoi tessellation approach. Then, particles were pluviated through a funnel into a cylinder. Once the soil particles settled in a static state, the cylinder was subjected to horizontal sinusoidal vibration for a period of 20 seconds. The same procedure for sample preparation was performed in the laboratory. The results of pluviation and vibration tests were recorded and compared to those of simulations. A good agreement has been found between the results of simulations and laboratory tests. The findings in this study reinforce the idea that physics engines can be employed as a geotechnical engineering simulation tool.

“…In the case of both braking and turning loads, the mass distribu tion changes, as well as the center of gravity of the vehicle [15,16,29]. Assuming that there is no mass transfer in the z axis, since the car has not shock absorbers, as well as the fact that if there is a mass transfer in the y axis, it will be negligible, then the new COG shown in Table 17.…”

The design of an electric urban car's chassis for the "Shell Eco Marathon" competition takes into account the usage and the type of the vehicle. The most critical factors of designing the new chassis are: the reduction of the weight, improvement of strength and stiffness and reduction of material and manufacturing cost. Towards this direction, a new design approach for a lightweight carbon-fiber reinforced epoxy (CFRE) monocoque chassis, is proposed, which conforms to structural, ergonomic and aesthetic requirements. For the development of this innovative approach, the parametric design method was chosen, in order for the design to be modified easily. The chassis efficiency, in terms of high strength in low mass, was obtained by following appropriate design steps and rules which conform to the vehicle structural and dynamical constraints and by choosing the composite material CFRE. Additionally, a method that calculates the mechanical properties of the composite material CFRE is presented. Furthermore, a model has been created, which calculates automatically the total loads applied on the vehicle's chassis. Worst case stress scenario was chosen and the model's output was evaluated for the new chassis design.

Abstract. In this paper, we conduct theoretical analysis on the novel computer assisted film and the television animation design pattern based on the computer graphics theory and three-dimensional modeling structure optimization. Computer graphics rely on itself, the visualization technology of the data and graphics can be effectively combined, graphic display is a major direction in development of computer graphics. To follow the trend, we analyze the issues from different perspectives. Computer graphics applied to computer animation as success of development of flight simulator prompted the application of computer graphics to television, film and advertising industry.
