CN-122016030-A - System and method for indicating non-ideal conditions of a drum of a compactor

Abstract

A system for indicating a non-ideal condition of a drum of a compactor includes a sensor coupled to the drum of the compactor that generates a signal indicative of a current vibration amplitude of the drum. The system also includes a controller including one or more memories and one or more processors. The one or more processors receive a signal from the sensor indicative of a current vibration amplitude of the drum, compare the current vibration amplitude of the drum with a nominal range of vibration amplitudes, determine whether the current vibration amplitude exceeds the nominal range of vibration amplitudes, and generate an output signal if the current vibration amplitude exceeds the nominal range of vibration amplitudes. The output signal is indicative of a non-ideal condition of a drum of the compactor.

Description

System and method for indicating non-ideal conditions of a drum of a compactor Technical Field The present disclosure relates to a compactor and, more particularly, to a system for indicating a non-ideal condition of a drum of a compactor, and a method for indicating a non-ideal condition of a drum of a compactor. Background Compactors are commonly used to compact materials such as asphalt, sand, aggregate, rock, clay, concrete, or other such materials. The compactor includes one or more rollers that contact the material to be compacted. The drum may have a smooth outer shell or the drum may be a padded drum. Each drum is equipped with a vibration system that vibrates the corresponding drum at a desired vibration frequency and a desired vibration amplitude to compact the material. The rollers of the compactor may wear over a period of time due to interactions with the compacted material. For example, cracks may propagate in drums having smooth outer shells, which may result in a compactor being inoperable and/or inefficient compaction operations. Furthermore, wear of the plurality of pods disposed on the pod drum may result in uneven support of the compactor and uneven compaction. In some examples, material compacted by the compactor may accumulate on the shell of the drum or on the pads of the compactor. The accumulation of material may increase the mass of the drum, which in turn may reduce the vibration amplitude of the drum. The reduction in vibration amplitude may reduce the effectiveness of the compaction operation performed by the compactor and may require an increased number of passes to achieve the compaction target. U.S. application Ser. No. 2020/0378554 describes a work machine including a compactor drum, a controller, and an output device. The compactor drum includes a vibratory system including at least one bearing and lubricant received by the at least one bearing, the at least one bearing supporting rotation of the vibratory system within the compactor drum. The controller is configured to monitor at least one physical characteristic of the vibration system over a specified time and predict a remaining useful life of the lubricant based on the at least one physical characteristic. The output device is configured to generate an output indicative of the remaining useful life.
