| Abstract: | As catenary hard spot seriously affects the normal running of electric locomotives,a method applying strain acceleration transducer for measuring catenary hard spot in the electric railway is thereby introduced.The operating principle,mathematical model,frequency features and measurement circuit of the acceleration transducer are analyzed.Then,the designing parameters of the transducers are derived and the composition of the detecting system as well as installation position on the electric locomotives are presented.Finally, the field test results are obtained.The system is proved to be stability and reliability,which satisfied the intended designing demand. |
