Publication number: 20250137885Abstract: In one instance, disclosed herein is a computer-implemented method for monitoring an undercarriage of a track-type machine, the computer-implemented method comprising: accessing a reduced order model (ROM) corresponding to the track-type machine; receiving an estimated wear level of at least one undercarriage component of a track-type machine and machine signal data generated by the track-type machine; generating an updated estimated wear level of the at least one undercarriage component using the estimated wear level, the machine signal data, and the ROM; and comparing the updated estimated wear level of the at least one undercarriage component to a wear level threshold.Type: ApplicationFiled: November 1, 2023Publication date: May 1, 2025Applicant: Caterpillar Inc.Inventors: Wenming Zhao, Xuefei HU, Cheng Yu, Zhiyong Hu, Daojie Zhang

Patent number: 12124231Abstract: An electronic control module (ECM) on-board a machine executes a reduced-order model configured to generate virtual sensor data associated with a machine component based on sensor data measured by actual sensors. The ECM can also execute a machine learning model configured to generate offset data for the sensor data and/or the virtual sensor data, based on operating conditions, an age of the machine component, and/or other factors that the reduced-order model may not consider. The sensor data and/or the virtual sensor data, adjusted based on the offset data, can indicate whether the machine component has failed or is predicted to fail at a future point in time, and/or a remaining usable life of the machine component.Type: GrantFiled: November 30, 2021Date of Patent: October 22, 2024Assignee: Caterpillar Inc.Inventors: Yanchai Zhang, Wenming Zhao, Chunhui Pan, Daojie Zhang, Xuefei Hu, Shiferaw Damtie Beyene, Nathan J.

Publication number: 20230354789Abstract: An indirect selective breeding method of high-collagen meat geese includes : (1) obtaining a curve equation y=0.017x+0.026; (2) rearing goslings to young geese; (3) measuring the length, width, and height values of the knobs of the geese, and calculating to give the collagen content according to the curve equation obtained in step (1); (4) sorting the geese in descending order according to the collagen content and keeping the geese with collagen content ranked top 50% as breeding geese; (5) after the geese lay eggs, hatching the goose eggs into goslings; and (6) repeating steps (2)-(5) for selective breeding over generations. The indirect selective breeding method is simple and easy to implement. A new strain of meat geese with high collagen content can be obtained from selective breeding simply by measuring the length, width, and height of the knobs of geese of each generation.Type: ApplicationFiled: May 26, 2022Publication date: November 9, 2023Applicant: YANGZHOU UNIVERSITYInventors: Yu ZHANG, Qi XU, Yang ZHANG, Zhengfeng CAO, Wangyang JI, Zhixiu WANG, Guohong CHEN, Wenming ZHAO

Patent number: 11619670Abstract: A detection system for detecting winding faults, such as inter-turn winding faults in the stator and/or rotor of an electrical generator utilizes one or more vibration sensors that can be located on a generator housing. The vibration sensors make mechanical vibration measurements and transmit them to a fault analyzer. The fault analyzer can compare the measured vibrations with a threshold to determine if a winding is occurring. In an embodiment, the fault analyzer can convert the mechanical vibration measurements from the time domain to a frequency domain to facilitate analysis.Type: GrantFiled: April 1, 2020Date of Patent: April 4, 2023Assignee: Caterpillar Inc.Inventors: Yanchai Zhang, Wenming Zhao, Yong Sun, Xuefei Hu

Patent number: 11428704Abstract: A system and method for protecting a genset from pole slip is disclosed. The system may comprise a generator, a prime mover and a controller. The generator includes a stator and a rotor. The prime mover is configured to drive rotation of the rotor. The controller may be configured to: determine mechanical status of the generator based on data associated with a translational displacement of the rotor; determine electrical status of the generator based on (a) a load angle or (b) the load angle and a rate of change of the load angle associated with rotation of the rotor in the stator; determine an operating condition of the generator based on fusion of the mechanical status and the electrical status; if the operating condition is a pole-slip-warning, activate an output member to display or emit a warning; and, if the operating condition is a pole-slip, activate a protective action.Type: GrantFiled: January 9, 2020Date of Patent: August 30, 2022Assignee: Caterpillar Inc.Inventors: Zhijun Cai, Yanchai Zhang, Wenming Zhao, Yong Sun, Xuefei Hu, Eric Wayne Ohlson, Suresh Baddam Reddy
