Study On Test Methods And Criteria For Radiated Susceptibility Of Vehicle Electrical/Elctronic Components

With the increase demand of spatial measurement,space coordinates measuring instruments have rapid development.Therefore,the standard used for calibrating the these space coordinates measuring instrument also should be complementary developed.Bat as the inspection standard mentioned in calibration specifications of coordinates measuring machine has not been widely used in our country at present,the main reason is that space coordinates measurement calibration just started in our country,so there does not have a very reliable and stable bat detection device.By comparing the advantages and disadvantages of the bat detector design method at home and abroad,taking example by foreign method of laser interference measurement,and designing,the research developed a ball pitch detection device with one-dimensional,two-way and high-precision.Each of the components will be researched.Through the comparison of the same type,the more suitable hardware facilities for the of the apparatus will be choose.In the process of device establishment,through the adjustment to optimize between parts to achieve the technical indicators.Some parts will have error during establishment.Therefore,some design will reduce the error during the process.After completing the device,through a series of test data,contrasting the bat in foreign testing data,there comes to the conclusion that the measuring uncertainty of the detection device is within the scope of the evaluation.The device could not only lay a firm foundation for domestic bat quantity traceability,but also play a key role to improve the precision measurement in our country and the space coordinates of quantity traceability levels.It can reduce the cost of our country's advanced manufacturing industry,narrow the technology gap with foreign,and make the development of related industries more rapidly.
