【Abstract】 To precisely detect the degree of compaction and improve the quality and efficiency of road roller, the paper establishes a systemic mathematic model about vibrating wheel and soil, and develops a tester for degree of compaction on vibrating roller. The tester is equipped with an accelerated sensor and an USB interface. It has wide frequency hand (0.30~50 Hz), little measuring error(≤3%), high linearity (0.5%) and friendly operating in terface.更多还原
