Description

The high energy-saving new public transportation system called "Eco-Ride" has been developed to solve various traffic issues. Eco-Ride vehicle does not have on-board driving devices. The vehicle runs using potential energy with technologies of the roller coaster. The test track and the prototype vehicles were made to examine the basic performance. The secondary suspension was used as the suspension mechanism to reduce vibration transmission from the track to the vehicle body. Three kinds of secondary suspensions were installed in the newer prototype vehicle. A vehicle dynamics model was derived with consideration for the secondary suspension. Their effects of reduction of vibration transmission were confirmed by simulation. Then, the vibration acceleration was measured when prototype vehicles equipped with the secondary suspension ran on the test track. It was confirmed that vibration transmission was drastically reduced by secondary suspensions through vibration measurements.
