Abstract

Anti-jamming techniques were studied in dynamic stress test on bogie structure form the hardware and software. The paper sums up the hardware techniques like compound protection technique and anti-radiation jamming technique; and mainly introduces the software techniques such as zero drift signal processing, digital signal filtering processing, and wavelet signal processing. Additionally, an algorithm 'three-peak-valley stress value compare' is proposed in the wavelet signal processing. The results in application prove these measurements help to provide valid and reliable stress-time history signals for programming the bogie stress spectrum.
