Research on Shielding Technique in Dynamic Stress Measurement on Bogie Frame

SHEN Yan peng, LIU Zhi ming (College of Mechanical and Electrical Engineering, Northern Jiaotong University, Beijing 100044,China)  
Based on analysis of sources and paths of interference and sensitive equipments, shielding technique was studied in dynamic stress measurement on bogie structure. The paper sums up the hardware techniques, such as compound protection, earthing, power source and the software techniques, such as zero drift signals process, digital signals filtering process, little wave signals process. Good results in application are obtained.
