Analysis of Equipment & Body Vertical Coupled Vibration Characteristics Based on Excitation of Single Bogie

Abstract

It is the inevitable trend for the development of railway vehicles in China, which is high speed and heavy haul. But high Speed and heavy load operation condition will also worsen the running environment of whole vehicle system and components or assemblies, which will be a threat to the running safety. Meanwhile, vibration problem caused by high speed running will become more and more prominent. Railway vehicle is a complexity dynamic system with multidimensional and multi-DOF, and its dynamic performance is the key factor to the running safety and stability. So, study on the dynamic characteristics between body and equipment is of key technologies for the design of high-speed train.
