Same Taper Measurement Test Equipment Design And Realize

This article focuses on helicopter rotor taper test measurement equipment design.Main article on the development of thesis topics,same taper of the working principle of measuring system,model structural design and hardware circuit design and debug,such as aspects of the investigation.At the beginning,the article introduced the development of taper measurement methods at home and abroad.It also showed the importance of rotor taper method of measuring,at the same time,existing test platform to do a simple introduction.Based on the existing platform for a comparative analysis of research to determine the experimental model of laser measurement of the working principle,and learning from the successful experiences of our predecessors on the basis of innovation.The helicopter rotor taper measurement test equipment of the job are the main part of optical path of the rotor model and the hardware circuit part.Article of Chapter 2 and Chapter 3 introduces these contents.Optical design of a direct impact on the entire system of measurement accuracy.The sets of test model will be a bunch of laser spectroscopy beam divided into three principle,eliminating coplanarity adjustments,and improved the measurement accuracy.The part of hardware circuit from the signal processing,counting,watchdog circuit and so introduce a system to achieve the main circuit.In the presentation of rotor model, begin from model design criteria,the article introduced the whole process of the helicopter rotor model being scaled down in detail and showed rotor model's specific shape and size.Finally,article discussed the equipment between the upper and lower machine communication,compared several popular means of communication and chose CAN-bus communication.Then the article introduced the CAN-bus communication features,technical specifications,etc.According the working principle of the CAN-bus hardware circuit analysis,the article designed the lower machine assembly language procedures and introduced the upper machine program working principle and interface.Thesis through upper and lower machine debugging concluded its rotor taper measurement equipment design and the sets of device measurement accuracy has reached the request.
