In this study, design of tube type linear generator, which can generate electricity from suspension systems of electrical vehicles, has been realised. Information about widely-used suspension systems has been given and advantages and disadvantages of linear type electro-magnetic dumpers have been mentioned. Analytic design of tube type linear generator has been made for passive suspension system. In line with obtained sizing parameters, numerical analyses have been made in Ansys-Maxwell programme and results of such analyses have been examined. Prototype of analyzed tube type linear generator has been made. Measurements of magnetic flux density and simulation results in air gap have been compared. The linear generator designed has been applied for passive suspension. The experiments of the linear generator with 20, 40, 60, 80, 100, 120 and 130 mm stroke length were performed, respectively. During the experiments, a frequency range of 1 Hz to 5 Hz was chosen. The highest speed was 1,3 m/s and the generated pk-pk voltage value was 37.7 volts. The speed value of the generator changes according to the road condition. Therefore, a converter is needed for battery charging after the generator output voltage is rectified. © IMechE 2021.
