EMC immunity tests
open-area partially shielded test site model
Opis:
The question of testing of vehicles and their subassemblies, especially in the range of electrical and electronic equipment, is very extensive. The scope of the relevant tests becomes wider and the requirements, especially in the range of safety, reliability and comfort, become higher. Of particular significance, are in recent years, tests concerning electromagnetic compatibility (EMC) of whole vehicles and their subassemblies. A survey of basic standardized EMC test methods is presented in the paper. Moreover, an alternative test method of vehicle immunity worked out by authors is proposed. The method has been verified by using the open-area partially shielded test site (OAPSTS) model and compared with standardized methods contained in ECE UN Regulation No. 10 and EU Directive 2004/104/EC. Tests of vehicle immunity to electromagnetic field have been performed using the model of OAPSTS and the vehicles: Citroen-Berlingo, Skoda-Octavia and Daewoo-Lanos. Estimation of basic statistical parameters has also been worked out. The obtained results show that the proposed method is reliable and, on the other hand, it is more accessible and less expensive than the standardized methods in which employing of very expensive absorber-lined shielded test chambers is necessary. The present paper extends the results obtained in [6, 7].

Opis:
The technological development in automotive industry that can be observed during the last several decades, especially during the last decade, causes that share of a vehicle electrical and electronic equipment constitutes over 30% of its total worth. This equipment essentially affects the safety of the driver and passengers as well as the driving comfort. In order to fulfill the growing requirements in the range of vehicles safety and reliability, conducting of numerous tests of the electrical/electronic equipment, including tests of electromagnetic compatibility, are necessary. As is known, EMC tests are expensive and difficult to reach, mainly due to the necessity of employing very expensive absorber-lined shielded test chambers. For this reason, there is a need for studying more accessible and less expensive EMC test methods, in particular, by using open-area partially shielded test sites (OAPSTS). In this paper, a model of OAPSTS is described. The model ensures that the tested vehicles are partially separated from the environment by shields attenuating electromagnetic waves. These shields have been made of electro-conductive fabrics worked out in Poland. Tests of vehicle immunity to electromagnetic radiation have been performed using the model of OAPSTS and the following vehicles: Skoda Octavia 1,8 and Daewoo Lanos 1,6. Estimation of parameters of the OAPSTS model for four variants of absorbe s placement has been worked out. The tests have been performed according to EU Directive 2004/104/EC and ECE UN Regulation No. 10.

Opis:
Fast development of electronics in recent years causes that the number of various kind electronic systems is still growing. This causes also that requirements concerning tests of electromagnetic compatibility (EMC) of whole vehicles as well as their electric/electronic subassemblies become more significant. In this paper, the most important requirements of international regulations in the range of EMC, i. e., ECE UN Regulation No. l0 and EU Directive 2004/104/EC, have been outlined. Moreover, results of investigations of electric field strength inside of three chosen vehicles have been presented. The tests have been performed, according to Directive 2004/104/EC, in an absorber-lined shielded chamber in thefrequency band 20MHz to 2000MHz and at the electric field strength in the reference point equal to 30V/m. The most important results of these investigations have been presented in the form of graphs of electric field strength distribution in various points of tested vehicles. Individual electric/electronic devices o f a vehicle are exposed to electromagnetic field with a very wide range of values of electric field strength - depending upon a device position in a vehicle, vehicle type and antenna polarization. Values of electric field strength inside of a vehicle may essentially exceed the values recommended by standards for immunity tests of electric/electronic subassemblies.
