This paper describes a method for approaching an arbitrary parameter with initial outline, slider and simulation model, systematical and quantitative bond graph model of vehicle dynamic system. It illustrates a typical bond graph and object models using the three basic modules of the software. For brevity, only small problems are considered for simulation of vehicle dynamic system model. Bond graph techniques reveal its strength and beauty in developing a clear and simplified model for vehicle dynamic system. Fast Fourier Transform (FFT) generates discrete Fourier transform of a time-varying signal and stores it into a disk file containing discredited numerical values for all the system states, ranging over the entire simulation interval. In this paper, a vehicle dynamic Modeling and Simulation involving three partners viz., Vehicle model, Vehicle parameter and Vehicle simulator, are taken into consideration. This process consists of both modeling and simulating closely associated with each other. Vehicle dynamics is the science that studies the kinematics of wheeled land vehicles with its dimensions and benefits to mechanisms, suspensions and steering mechanisms. The dynamics of computer models of vehicles using Bond graph technique originated by H. M. Paynter, presents a tool for continuous system modeling in a graphical sense, by generalizing the physical phenomenon such as: Mechanical Dynamic System. The role of computerized modeling and simulation in engineering design continues to increase as companies are striving to gain competitive advantages by reducing the time required to move from concept to final product.

Result Analysis

The paper describes the technique for presenting quantitative and systematic modeling and simulation using Bond Graph for the vehicle dynamic system. It is based on the relative contribution of the new generation of a system equation, expression, result analysis and simulation through graphical display. The portioning algorithm can be employed to the existing automated modeling techniques for efficient, accurate simulation towards the design of the vehicle dynamic system. The design of control oriented four wheeled vehicle is widely recognized to be a very challenging task. This allows accounting for the driver turn angle which necessitates about visualizing the real driving behavior and its effects on the overall vehicle dynamic system. The study also illustrates an introduction to vehicle dynamics with emphasis towards the influence of its various properties. It also discusses the steady–state behavior of simple automobile models and transient motion when small and large steering inputs and other disturbances are employed. The effect of various shape factors and type of characteristics on vehicle handling properties is analysed. In order to design a controller, a good model representing the dynamic system is needed. From the input parameters considered, the results of the modeling and simulation of vehicle dynamics through the Bond Graph are found efficient and more accurate.

Bond Graph Modeling

Following the technological advances in recent decades, advanced electronic systems linked to the gas turbine industry are increasingly considered by the designers of this field. For this purpose, new airborne systems in conjunction with jet engines are developed, which are incorporated in many challenging design problems such as control law and configuration design. Thus, a comprehensive modeling structure is needed that can bolster the integrity of the system development such as the bond graph approach, which is known as an efficient method for modeling complicated mechatronic systems. In this paper, modeling and simulation of a jet engine dynamic performance and aircraft motion are achieved based on the bond graph approach. At first, the electric starter bond graph model is constructed and physical relationships governing each engine component are obtained. In the aftermath, the modulated energy fields are developed for the jet engine components. Subsequently, the bond graph model of the engine is numerically simulated and experimentally tested and verified for a small jet engine. Finally, bond graph modeling and simulation of integrated engine and aircraft system is presented. The test results indicate the acceptable accuracy of the modeling approach which can be applied for innovative diagnosis and control systems design.

Steering Mechanism

The paper creates a bond graph model of the control system of a hydro-mechanical stepless steering mechanism for a tracked vehicle in 20Sim software. Based on this model, the dynamic characteristics of combining and separating of the brake during the range shift process is analyzed. The result of simulation shows that there is a 0.1s interval during the shift process of the two brakes which may generate a power interruption in vehicle steering process. In order to resolve this problem, the brake which is coming to combine can be charged oil first, and then the brake which is coming to separate is discharged. That means the two brakes have an oil-filled state at same time. The result of simulation indicates the reasonable value of the time is 0.08 second. At last the paper brings forward an improvement to the control system to meet the requirement of oil-filled state at same time.

Power Switching

A systematic method for constructing models in the complementarity framework from a bond graph is proposed. Bond graphs with and without storage elements in derivative causality are considered. The proposed method allows the study of switching systems represented by a bond graph model of fixed causality. The proposed methodology allows the complementarity framework to be exploited in different engineering areas by using bond graphs. The idea of representing a unidirectional switch with a model that is essentially the same as a diode is presented. By employing a similar representation for diodes and switches, the modeling and simulation of power switching converters are simplified and become more intuitive. Two application examples are shown. A non-inverting buck-boost converter and a zeta converter with an element in derivative causality are simulated.

Body Dynamic

This paper presents a bond graph model of a maritime crane lifting system comprised of a 3DOFs crane with three revolute joints, a winch, a segment of wire, and a pendulum load. The multi-body model contains the dynamic properties of the system and 3D animation of the operational behaviors. Lagrange’s method was used to derive the dynamic equations of the multi-body crane. Lagrange’s equations provide a clean elegant form for implementation using a special type of bond graph called IC-field. The model based on the bond graph contains interfaces to other domain models, e.g. input devices, control systems, hydraulic actuators, and sensors. Maritime crane operations are challenging due to the impact of heavy lifting, system stiffness and load sway resulted from the unstable working platform. The industry increasingly demands an overall virtual environment for modeling and simulation of maritime operations. The accomplishment will highly increase the efficiency and effectiveness of product and system design, new component and control algorithm testing, and operator training. The multi-body dynamic model is the core building block for modeling and simulation of maritime crane operations.
