Dynamic Simulation of a Korean Ezplosive Subsoiler for the Determination of Vehicle Stability and Safety
The objective of this study was to analyze the stability and safety of an explosive subsoiler vehicle for use in Korean orchards using a multi-body dynamic analysis program RecurDyn 6.4.. Various physical properties of the vehicle, including mass, center of mass, and moment of inertia, were determined based on three dimensional (3D) geometric data obtained using the CAD program SolidWorks 2008.. Using the recursive dynamic solver, the crossway and sideway overturning motions of the vehicle were simulated. The Jamosi-Hanamoto model was applied to derive contact equations between soil and traction. A study comparing the static and dynamic responses revealed that the 3D model was effective in determining various properties of the vehicle. The maximum angles for stability were estimated to be 38 degrees and 37 degrees in the forward and side directions, respectively. The range of the safety limits varied with different levels of soil property variables, such as terrain stiffness, cohesion, and the angle of shear resistance. The simulation results showed that sandy loam soil provided safer conditions for the vehicle than did dry sandy soil.
