Vibration tests on different electric buses and routes in the city of Győr

In the vibration tests, three-axis accelerometers were installed on different electric buses (BYD, IKARUS). One sensor was placed on the chassis and another on the body. During the measurements, two directions of two sensors were recorded using an oscilloscope. On five routes, 10 different sections were recorded. We evaluated the root mean square (RMS) pulsation values of the vibrations in each case, as well as the maximum amplitude vibration of each section. The comparison tables show that there can be a difference of up to 40% in vibration intensity between the lowest and the highest loaded section. The comparative data show that the effect of chassis damping is to reduce the body vibration to 1/6 of the chassis load.
