- Abstract
Compression garbage trucks mainly work on fresh municipal solid waste (MSW), while fresh MSW has complex composition, high compressibility, high water content. Less research has been done about fresh MSW. Its uncertain mechanical property limits the simulation of garbage compression process, thereby limits the compressor structure analysis and optimization for compression garbage trucks. In order to obtain the mechanical properties of fresh MSW, a special test device combining the direct shear test with the confined compression test was designed, manufactured and assembled. A total fifteen tests from four batches fresh MSW were conducted with the special test devices. And the Duncan-Chang constitutive model parameters by summarizing and organizing test data. Finally, the confined compression test was simulated with the constitutive model, and the constitutive model parameters was verified. The research provides a basis for the simulation of garbage compression process of the compression garbage truck.
