Abstract:
A system includes a location determining circuit configured to acquire position information of a vehicle system moving along a route. The system also includes a controller circuit having one or more processors. The controller circuit is configured to calculate curvatures of the route, based at least in part on the position information, to form a curvature waveform. The controller circuit is further configured to generate a route map based on the curvature waveform.
Abstract:
Systems and methods provide variable spring stiffness for weight management in a vehicle. One system includes a plurality of springs and a plurality of spring retainers configured to adjust a number of inactive coils of the plurality of springs. Additionally, a motor is provided that is connected to the plurality of spring retainers and configured to actuate the spring retainers to adjust the number of inactive coils of the plurality of springs. Further, a controller is provided that is coupled to motor to control the motor to actuate the spring retainers to adjust the number of inactive coils of the plurality of springs.
Abstract:
A system for reducing vibration in a wind turbine includes a mass structure having at least one hole extending therethrough; a rod having a top threaded portion, an upper level stop disposed on or below the threaded portion, and a fixed lower level stop disposed below the upper level stop. The mass structure has a designed weight and shape that, in combination with the adjustable axial distance between the upper level stop and the lower level stop, is designed to provide a properly tuned system for a particular frequency. A base having an aperture designed for receipt of the lower level stop therein is configured for attachment to a component of the wind turbine.
Abstract:
Systems (142) and methods for weight transfer in a vehicle (100) are provided. One system (142) includes a plurality of springs (132) and a plurality of moveable spring seats (138) configured to adjust a length of the plurality of springs (132). Additionally, an actuator (170, 1170) is provided that is connected to the plurality of moveable springs (132) and configured to move the moveable spring seats (138) to adjust the length of the plurality of springs (132). Further, a controller (114) is provided that is coupled to the actuator (170, 1170) to control the actuator (170, 1170) to adjust the length of the plurality of springs (132).
