    The vibration of the bogie and the car body becomes remarkable with the speedup of the train, and there are effects, such as safety, riding comfort, rails or ground facilities. This is a very important problem. The problem of vibration in railway vehicles is a very important matter in terms of safety and riding comfort, and a detailed analysis is required. Our experiment was carried out using the roller rig model equipment in 4 kinds of wheel tread gradient( 1/10 to 1/40). The vibration of the railway vehicle is mainly caused by wheels and bogies running on the rail, and it is transmitted to the car body. Of great concern is the danger of derailment, when the hunting occurs at high speed and it has an adverse effect on riding comfort. In this paper, the hunting or phenomenon of railway vehicle generated at high running speed in comparison to low speed is verified using the roller rig model equipment. The purpose of this study is to clarify the relation with the natural vibration of the car body from the viewpoint of the bogie hunting phenomenon.

    In recent years, as a natural disaster in Japan, there were damage from the 2011 Tohoku Region Pacific Offshore Earthquake and the 2016 Kumamoto Earthquake. In the event of a disaster, people who are difficult to evacuate can not escape, and sometimes they die. In this research, we investigate damage situation on natural disasters in recent years, and make basic experiments on running experiments simulating bad roads after disasters. Based on the results obtained from experiments, we aim to propose a wheelchair that can be utilized at the time of a disaster or after a disaster. In addition, riding comfort analysis was carried out using the vibration measuring device during the experiment. From the results of the research, it was shown that the introduction of a wheelchair driven vehicle aimed at reducing the load assuming natural disasters is effective. Also, by increasing the size of the front wheel, it is possible to alleviate the gap between the step and the step. It is possible to reduce the load exerted on the body by using a tire with less electric assistance or less resistance.

    A large number of vibrations are applied to a railway vehicle while it is running, and the natural vibration phenomenon occurs when the frequency of the vibration approaches the natural frequency of the vehicle itself. It is a common phenomenon but it is also an issue to prevent it from occurring, and it is necessary to clarify each natural vibration mode of the vehicle. In this study, we performed a running experiment by using a railway roller rig. By PSD analysis of the vibration acceleration at each measurement point, it is clear where the natural vibration phenomenon occurs at lateral and we know the experimental value through running experiment. We also modeled horizontal 6 degrees of freedom of the roller rig model, calculated the natural frequency, and grasped the theoretical natural vibration mod by using numerical analysis software. By comparing the theoretical value and the experimental value, the natural vibration analysis method was established.

    In recent years, research and development of personal mobility, which is said to be a compact single-seat mobility support device as one of the next generation transportation, has been promoted by companies and research institutions. Many of the vehicles that have been developed have a distance between the driver's boarding position and the road surface, and there are riding methods such as standing and sitting. In this study, wheelchairs and self-propelled vehicles that the driver himself drives are defined as a part of personal mobility, and the vibration analysis that affects the driver rather than driving and the effect on ride comfort are examined. In addition, the natural frequency obtained from the impact test is compared with the theoretical value.
