The design dynamic analysis model
-
Improving driver ride comfort of a wheel loader is important to avoid potential health hazards from the whole-body vibration. A fuzzy self-tuning of PID controller is designed to control the damping coefficient of Semi-active cab isolation system (SCIS) for a wheel loader. A dynamic model of a wheel loader is establish under survey conditions for analysis and evaluation.

The organization of this paper is as follows. In Section 2, the dynamic model of the quadrotor is presented, and the control problem is defined. Section 3 introduces the finite-time controller design and provides a stability analysis of the closed-loop system. Simulation results are presented and discussed in Section 4. Finally, Section 5 concludes the paper.

Supply chains are starting to be more and more powerful in reaction to transforming company atmosphere as well as innovation. This has produced issues in coping with the flow of resources as well as produced increased probability of interruption. As such this particular analysis evaluates the effect of dynamism on interruption orientations, financial performance, and resilience.

In this study, the algorithm was applied to a model of an unstable electrical system with a degree of 66 and reduced to degrees 8 and 15. Simulation results using Matlab showed that the HBT method was successful in reducing the order of the system and improved simulation time. The reduced-order system of degrees 8 or 15 can be used in place of the original system in applications in the time or frequency domain during analysis, design, simulation or implementation of electrical networks.

Behavioral models describe the internal dynamic aspects of an information system that supports the business processes in an organization. In this chapter, we describe three UML 2.0 diagrams that are used in behavioral modeling: sequence diagrams, communication diagrams, and behavioral state machines.

The investigation analyzes effects of clearance size in revolute and spherical joints with clearance on rigid-flexible dynamic of a space slider crank mechanism by finite element method. The model of the mechanism was designed by Solidworks and then velocity, acceleration, displacement, stress and contact force were determined by finite element analysis of rigid-transient dynamic in ANSYS.

In the mechanisms and machines operating at high speeds, the elastic vibration of links is inevitable. In this paper the dynamic modeling and controller design for a flexible four-bar mechanism are studied. The fully coupled non-linear equations of motion are obtained by using the Lagrange’s equations with multipliers for constrained multibody systems. The resulting differential-algebraic equations are solved using numerical methods. A simple PD controller is designed to reduce the influence of the elastic link on the desired motion.

Many medical imaging techniques utilize fitting approaches for quantitative parameter estimation and analysis. Common examples are pharmacokinetic modeling in dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI)/computed tomography (CT), apparent diffusion coefficient calculations and intravoxel incoherent motion modeling in diffusion-weighted MRI and Z-spectra analysis in chemical exchange saturation transfer MRI.
