Design And Implementation Of The Reliability Of The Airborne Communication System

In modern life, electronic equipment has penetrated the many aspects such as military, civil and so on. And the reliability of the communication system made of the electronic equipment is getting more and more people's attention. The reliability is the important indicator of measure the quality of the communication system.In the paper, we mainly implement the study and design of the airborne communications system made of ARINC ATR racking system. ARINC ATR racking system is strictly according to the standard made in airborne communications systems, which is the plug type of module structure and full cooling design. Then we mainly study the reliability of the airborne communications systems, thus to optimize the design of the airborne communications systems, which makes the reliable performance of the system be improved.In the paper, the airborne communication system firstly adopts the 3D CAD modeling, then we proceed the thermal simulation and thermal analysis through professional thermal simulation software ANSYS. Finally, according to the results of simulation, we optimize the structure design of airborne communications systems, which makes ARINC ATR racking system eventually achieve effective heat dissipation.In the paper, the components counting method is adopted to evaluate reliability indicator of the airborne communications systems. Reliability indicator mainly includes components failure rate and the average interval of failure time(MTBF). And the system adopts series model between the system module.According to the results of the forecast, we adjust the system components selection and variety to optimize the reliability indicator of the airborne communications systems, which eventually makes the system achieve the average interval of at least 200 hours down time.In the paper, we mainly test the electromagnetic compatibility characteristic of the whole system, which is according to the GJB151A-97 "military equipment and subsystem electromagnetic emission and .susceptibility requirements and GJB152A-97" military equipment and subsystem electromagnetic emission and susceptibility measurements" standard. And-aceording to the two standards, we research the measure items in the system.
