“…To generate such a physical viscoelastic model suitable for multi-physical system dynamic investigations, the bond graph (BG) modeling technique [13][14][15][16][17][18][19] is suggested in this paper. Working on the basis of physical system theory, the BG technique provides a continuous power exchange frame between the existing physical subdomains of a multiphysical system, and produces the behavior of the system on the basis of power conservative interactions between the existing energetic components of the system.…”

Understanding the true nature of viscoelastic behaviors in multi-physical systems has always been a challenging issue in system dynamic investigations, as each existing physical subdomain of the system may follow a different attenuation pattern during the dynamic process. In this study, to generate a viscoelastic model suitable for multi-physical domain dynamic investigations, a physical combined viscoelastic model is proposed. To this aim, by means of the bond graph approach, an energy-based conventional viscoelastic model is first generated, and its embedded dispersive mechanisms are interpreted physically. By including the interpreted dissipative mechanisms into the relative subdomains of an elastic domain, an energy-based combined viscoelastic model is then proposed. The obtained simulation results indicate that the proposed viscoelastic model is able to capture a variety of viscoelastic behaviors in the system with respect to the true physical nature of the system.

“…7 Dasgupta and Watton studied the performance of a multiple-input multiple-output pilot relief valve with parameter variations 8 ; the system was then modeled using measured parameters and analyzed in the transient and steady state. 9,10 Zanj et al developed nonlinear BG models of direct and indirect pressure control valves, 11,12 and investigated a range of dynamic behaviors of an indirect valve including nonlinear effects of flow forces, Coulomb friction, hydraulic resistances, and fluid chamber compressibility 13 ; the model was validated by experiment. None of these studies attempted to model the start period, as the traditional single-model BG approach used can only describe fixed degree-of-freedom (DoF) dynamics, whereas the dynamics of the start period are varying DoF in nature.…”

In this paper, a feasibility study on modeling the multi-physical dynamic behaviors of the start period of hydro-mechanical control devices is presented. Using a novel multi-model Bond graph approach, a nonlinear, variable degree-of-freedom, state-space model is developed for a typical pressure regulator during its start period. Simulation studies demonstrate the essential physical behavior of the regulator during the transient period, and confirm the integrity of the resulting nonlinear model of the system.

“…Inlet Outlet analysis, the bond diagram is usually used to analyze the characteristics of the hydraulic valves, such as Dasgupta's research on a proportional solenoid controlled piloted relief valve [20] and Zanj's research on an indirect hydrocontrol valve [21]. However, the deep-sea environment is greatly different from the environment of sea surface.…”

Taking into account the deformation of a designed direct-operated seawater hydraulic relief valve in deep sea, which might have a great influence on the stability of the valve, a mathematic model of the relief valve was established and stability analysis was conducted. As the fitting clearances between the damping sleeve and the damping bar play a key role in the performance of the relief valve, the fitting clearances after deformation under pressure of different ocean depths were obtained using finite element method. Applying the deformation data to the relief valve model, the stability and relative stability could be analyzed quantitatively through both the frequency domain analysis method and the time domain analysis method to detect the influence of the fitting clearance after deformation. The simulation results show that the seawater relief valve has a stable performance within 4000 meters deep under the sea.
