The invention discloses a device and method for adjusting the inherent frequency of a vestibule-type train windshield, the device for adjusting the inherent frequency of the vestibule-type train windshield comprises a connecting rod mechanism and a driving device, one end of the connecting rod mechanism is connected with the vestibule-type train windshield, the other end of the connecting rod mechanism is fixedly connected with the driving device of a compartment, and the vestibule-type train windshield is connected with the vestibule-type train windshield. And the driving device is used for driving the connecting rod mechanism to move so as to drive the vestibule type train windshield to locally deform within reasonable service capacity. The connecting rod mechanism is driven by the driving device to move, so that the vestibule-type train windshield is driven to locally deform within reasonable service capacity, the inherent frequency of the vestibule-type train windshield is changed due to deformation of the vestibule-type train windshield, resonance caused by superposition of the inherent frequency of the vestibule-type train windshield and the excitation frequency of a train aerodynamic load is avoided, and the service life of the vestibule-type train windshield is prolonged. The service life of the folding shed type train windshield is prolonged, and the folding shed type train windshield is prevented from being broken under extreme conditions.
本发明公开了一种调节折棚式列车风挡固有频率的装置及方法,所述调节折棚式列车风挡固有频率的装置包括:连杆机构和驱动装置,所述连杆机构的一端连接折棚式列车风挡,另一端连接固定于车厢的所述驱动装置,所述驱动装置用于驱动所述连杆机构移动,从而带动所述折棚式列车风挡在合理的服役能力内局部变形。本发明通过驱动装置驱动连杆机构移动,从而带动折棚式列车风挡在合理的服役能力内局部变形,折棚式列车风挡变形使其固有频率产生变化,从而避免折棚式列车风挡的固有频率与列车气动载荷的激励频率重合而产生共振,延长折棚式列车风挡的使用寿命,避免其在极端情况下发生断裂。
