Description

System and method for indicating compactor amplitude setting differences Technical Field The present disclosure relates to compactors, and more particularly, to a system for indicating a compactor amplitude setting differential and a method for indicating a compactor amplitude setting differential. Background Compactors are used to compact materials such as asphalt, soil, concrete, and/or other materials. The compactor includes a pair of rollers that contact the material to be compacted. Specifically, the pair of rollers includes a first roller disposed at a front end of the compactor and a second roller disposed at a rear end of the compactor. Each drum is equipped with a vibration system for varying the amplitude and frequency of vibration of the respective drum. In some cases, the compactor may be set incorrectly and the rollers may operate at different vibration amplitudes. The different vibration amplitudes of the first roller and the second roller may result in poor compaction and/or non-uniformity and may also affect the compaction density. Further, different vibration amplitudes of the drum may cause the drum to wear, may damage the drum, and/or may cause material damage/waste. Furthermore, due to non-uniform vibrations transmitted to the operator's cab of the compactor, different vibration amplitudes may increase operator fatigue and discomfort. WO2022079643 describes a vibratory compaction machine comprising a chassis, at least one drum and a control system. At least one roller is rotatable about an axis facing the Y-axis direction and mounted to the chassis to allow the roller to rotate on the work surface. The at least one vibration mechanism is configured to generate vibrations that are transmitted as impacts directed by the at least one roller in the Z-axis direction toward the work surface. At least one vibration mechanism is provided with a plurality of different amplitude settings. The control system is configured to measure an acceleration force of the at least one roller in a direction substantially corresponding to the X-axis direction, wherein the acceleration force is generated by the vibration mechanism and the X-axis direction extends in a direction substantially orthogonal to the Y-axis direction and the Z-axis direction.
