Simulation is an effective means for system development. A simulation system of the General aviation (GA) avionics using HLA is designed in this paper. The design and implementation process of federates is also described, taking the Cockpit Display federate as an example. The system has good interoperability, reusability and scalability, which meet the requirements of avionics simulation. The system can be widely used in GA avionics design and the training of pilots.

Virtual proving ground (VPG) are used effectively for commercial vehicle system development, human factor study, and other purposes by enabling to reproduce actual driving conditions in a safe and tightly controlled environment. This paper describes a virtual proving ground developed for design and evaluation of commercial vehicle and for driver-vehicle interaction study. VPG consists of a real-time vehicle simulation system, a visual and audio system, a driver handling signals acquisition system providing a realistic interface between the operator and the simulated environment, and 3D proving ground databases with areas suitable for various types of vehicle test tasks. The real-time vehicle simulation system simulates dynamic motion of realistic vehicle models in real-time. The visual system generates high fidelity driving scenes. The handling signals collection system acquires the steering, braking, accelerating, and shifting operation of driver. The pilot experiments carried out in the areas of vehicle handling and stability study are also presented to show the effectiveness of the developed VPG.

The Real

In this paper, we propose an approach to formally verify and rigorously validate a simulation system against the specification of the real system. We implement the approach in a verification and validation calculator tool that takes as input a set of statements that capture the requirements, internal conditions of the system and expected outputs of the real system and produces as output whether the simulation satisfies the requirements, faithfully represents the internal conditions of the system and produces the expected outputs. We provide a use case to show how subject matter experts can apply the tool.

The Development Strategy

To change the current phenomenon of “being an armchair strategist" in the study of DC servo system, the simulation system of that was developed using virtual reality technology. The principle of pulse width modulation was stated. The development strategy of simulation software was introduced. Some key problems and their solutions in system development were put forward, which includes the formation of triangular-wave modulation, calculation of armature current, assurance of duty ratio with average voltage. Finally, an example was given using the virtual DC servo system simulation. This paper provides an assistive tool for the R&D of DC servo system.
