摘要： A method for determining an estimated life of a mechanical device includes (1) acquiring a load spectrum of the mechanical device within a predetermined time range; (2) acquiring a lubricant state of the mechanical device within the predetermined time range; (3) determining a plurality of operating states experienced by the mechanical device within the predetermined time range based on the acquired load spectrum and the acquired lubricant state, and (4) determining an estimated life of the mechanical device based on the plurality of operating states of the mechanical device within the predetermined time range. Each operating state corresponds to a particular range of load values in the load spectrum and a particular degree of contamination in the lubricant state. The method may also determine the remaining useful life of a mechanical device. The method may be implemented in a device for determining the estimated life of a mechanical device.
