Abrégé

An automated hydraulic fracturing system and method for controlling various aspects of a fracking operation is disclosed. A master controller receives various operating parameters, such as desired operating conditions, information about a fracking site, information about trailers and/or other equipment at the fracking site, and/or sensor signals. The master controller may access one or more trailer model(s) that model various parameters of equipment (e.g., engines, transmissions, pumps, trailers, etc.) at the fracking site as a function of controlled operating conditions. The master controller uses the trailer models in conjunction with operating parameters to generate control signals that automatically control the various equipment at the fracking site to optimize various desired outcomes, such as reduced operating costs, reduced emissions, reduced idle time, increased efficiency, etc. The control signals are sent to controllers of the individual equipment to control the operations of those equipment and achieve an overall optimized fracking operation.

Abrégé

A device that includes a memory and a processor is disclosed. The processor may be configured to receive a control signal for operating a plurality of traction motors of a work machine. The control signal may include information relating to an actual speed of the work machine, a target speed of the work machine, and a generator speed of a generator operatively coupled to the traction motors. The processor may be configured to determine respective torque commands associated with the traction motors based on the actual speed and the target speed, and determine a generator power limit based on the generator speed. The processor may be configured to determine a threshold based on the respective torque commands and the generator power limit, adjust the respective torque commands based on the threshold, and cause the traction motors to be operated based on the adjusted respective torque commands.

Abrégé

A steel track chain component (162, 164, 166, 168, 202, 204), such as a track bushing (204), may be formed with a carburized portion (404), a hardface portion (412), and a core portion (410). The core portion (410) may be softer than the carburized portion (404), which in turn, may be softer than the hardface portion (412). This configuration of the various portions of the component (162, 164, 166, 168, 202, 204) may allow for relatively high wear resistance of the component (162, 164, 166, 168, 202, 204), as well as toughness. The core portion (410) may be mostly ferrite crystal structure, while the carburized portion (412) and the hardface portion (412) may include martensitic and/or austenitic crystal structure. The carburized portion (412) may be formed by carburizing the track chain component (162, 164, 166, 168, 202, 204) in a heated and carbon rich environment. The hardface portion (412) may be formed by welding a hardface alloy over at least a portion of the carburized portion (404).

Abrégé

A work machine (102) is disclosed. The work machine may include a frame (114), an implement system (110) coupled to the frame, one or more sensing devices (124), and a control unit (126) in communication with the implement system and the one or more sensing devices. The one or more sensing devices may be configured to transmit sensing device data relating to an operation of the implement system. The control unit may receive the sensing device data, compare the sensing device data with a stall threshold, and initiate a stall timer based on determining that the sensing device data satisfies the stall threshold. The stall timer may be configured to measure a stall duration. The control unit may compare the stall duration with a duration threshold, identify a stall event based on determining that the stall duration satisfies the duration threshold, and cause an action to be performed based on the stall event.

Abrégé

Process for clearing an autonomous machine (10) including first evaluating operation at a high curvature offline location (150). Following acceptable operation, the machine (10) is placed into service and evaluated at a worksite (11). Following acceptable worksite (11) operation, online operating speed of the machine (10) is increased incrementally, and performance reevaluated. Following acceptable performance characteristics, online operating speed of the machine (10) continues to be increased and revaluated until the machine (10) reaches maximum designated operating speed, or is evaluated as unacceptable, in which case the machine (10) continues to operate at the last acceptable online operating speed and identifies the unacceptable performance characteristic for further evaluation.

Abrégé

A retainer sleeve (400) includes an at least partially annular body (402) defining an axis of rotation (404), a radial direction (406), and a circumferential direction (408). The body (402)may also have a radially inner annular surface (410) defining a radially inner aperture (413), and a first anti-rotation feature (412) extending radially inwardly from the radially inner annular surface (410) including a sloping ledge (414) having a locking surface (416) that faces at least partially in the circumferential direction (408) and along a direction that is parallel to the axis of rotation (404), forming an oblique angle (436) with the direction that is parallel to the axis of rotation (404).

Abrégé

A method for determining part wear, such as using a wear metric, includes receiving, from a sensor (108, 110), sensor data representing a surface of a wear part (116). The method further includes determining distances between measured points (310) in the sensor data and points on one or more part models, which part models (214, 216) may include new part models (214) and/or worn or wear limit part models (216). The method further includes using a bounding model (222) that at least partially envelopes the part model(s) (214, 216) and the measured points (310) to determine a direction along which the distances are measured. The method may also include quantifying wear using the measured distances.
