Physical simulation of load displacement resistance of peat land surface on test bench

This article addresses resistance to displacement of loaded platform over the surface of natural peat land. We present the analysis of resistance forces applied to the platform during its displacement over the surface of water-flooded peat land. The diagram of forces affecting the moving platform on the surface of natural peat land is given. The resistance forces are added with the Archimedean force and the weights of the load and platform. The resistance forces and their generation factors are analyzed. The full-scale test data on displacement of a model over the natural peat land surface are presented. The relationship of the displacement resistance on the pressure applied to the peat land surface, as well as the dependence to estimate the required traction force to displace the platform are given. The test bench is designed for the detailed analysis of the platform front angle and friction properties of contacting surfaces. The physical simulation model allows deterministic variation in the platform weight, platform front angle and friction properties of contacting surfaces. The full-scale test results are compared with the test bench simulation data for the physical simulation relevance evaluation. The experimental data on the influence of the model platform front angle on the platform displacement resistance are presented. The traction force versus the peat land surface pressure is plotted for five values of the model platform front angle. The recommendations on reduction of the platform displacement resistance by selecting the optimized angle of the platform front are given.
