Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and in particular relates to a testing system and method for the center of mass and amplitude uniformity of steel wheels of road rollers. Background technique [0002] The vibration amplitude of the vibratory roller is the key performance index of the roller, which directly affects the compaction quality of the road surface by the roller. The uniform amplitude in the wheel width direction is the most basic requirement to ensure the uniformity of compaction. When the amplitude deviation between the left and right sides of the vibratory wheel is large , It will also affect the straight running performance of the roller. After experimental research, the offset of the center of mass of the vibrating wheel is one of the main reasons that affect the uniformity of the amplitude of the roller. However, due to manufacturing and processing precision and other reasons, the center of mass of t...

AI Technical Summary

Problems solved by technology

When the amplitude is uneven, it is difficult to achieve uniform amplitude by adjusting the center of mass of the steel wheel, and the process of measuring the amplitude of the roller in the field test is complicated

In the prior art, there is no device and method that can directly detect the center of mass and amplitude of the steel wheel of the road roller before the complete machine is assembled
