Research on Key Influence Factors of Dynamic Pantograph Lifting in Pantograph-catenary System
摘要
Abstract
Taking the pantograph-catenary system in railway vehicle system as the research object,and with the aim at the dynamic problem of pantograph lifting caused by AC/DC switching during train operation,this paper establishes a contact dynamic model of pantograph-catenary system,and verifies the accuracy of the model by ground test.Based on this model,the orthogonal experiment method is applied to explore the key factors affecting the dynamics of pantograph lifting and the regularity of the dynamic performance under the condition of stagger of contact wire,and reasonable parameters range of pantograph lifting in pantograph-catenary system is abtained.The results show that pantograph head quality,pantograph lifting speed and contact wire stagger position are the key factors affecting pantograph-catenary dynamics under pantograph lifting.关键词
