Problems solved by technology

And there is a certain lag in wiring harness design, which is generally 3-6 months behind the system design. Therefore, at the same stage, the available information for wiring harness design and weight estimation is relatively small, resulting in large errors in wiring harness weight estimation before the completion of proofing coordination.

Abstract

The invention belongs to the field of aircraft weight engineering, and particularly relates to an aircraft whole-aircraft wire harness weight estimation method based on electric equipment information. The method comprises the steps of 1, determining an electric equipment range according to characteristics of all system equipment of the whole aircraft, and estimating the weight of the electric equipment; 2, determining size data of an electric equipment area according to the arrangement position of the electric equipment on the machine; 3, estimating the weight of the whole-aircraft wire harness according to an aircraft whole-aircraft wire harness weight estimation formula based on the electric equipment information; and 4, calculating an estimation error of the weight of the full-aircraft wire harness, and comparing the estimation error with an estimation error obtained by adopting other methods including an original accurate-aircraft method. According to the method for estimating the weight of the whole-aircraft wire harness of the aircraft based on the electric equipment information, the estimation precision of the weight of the whole-aircraft wire harness in the early stage of the scheme stage can be greatly improved, the problem that the estimation error of the weight of the wire harness in the preliminary design stage is large is effectively solved, and accurate control over the weight of the wire harness is achieved.

Description

technical field [0001] The application belongs to the field of aircraft weight engineering, in particular to a method for estimating the weight of aircraft wiring harnesses based on electrical equipment information. Background technique [0002] There are hundreds of wiring harnesses on modern aircraft, and the weight of the wiring harness is an important part of the weight of the aircraft. With the development of information technology, the onboard power system is becoming more and more complex, and the information cross-linking between devices is increasing, resulting in The weight of the wiring harness and the ratio of the weight of the wiring harness to the weight of the aircraft are showing a gradual increase. [0003] There is a lot of uncertainty in the design of the wiring harness. Factors such as system schemes, equipment position adjustments, and laying path changes have a direct impact on the wiring harness, and the relevant factors can only be determined after th...
