<p>In response to the problem of the lack of a systematic simulation parameter measurement methods and calibration process for the dwarf-type plant stems, physical measurement methods for the simulation parameters of the dwarf-type plant stems were optimally selected: the Poisson's ratio and elastic modulus are measured by compression tests, the static/rolling friction coefficients are measured by the inclined plane method, and the coefficient of restitution is measured by the pendulum method. Moreover, a calibration method for the contact parameters of dwarf-type plant stems was proposed: The intrinsic and contact parameters of pod pepper stems is measured by physical tests using pod pepper plants as an case of dwarf-type plants. A discrete elemental model of pod pepper stem is established based on DEM, the repose angle of pod pepper stems is measured by the physical test of the plate-pulling method, and the contact parameters are calibrated using the design of experiment (DOE) method in conjunction with the DEM simulation. The obtained optimal contact parameter combinations are applied to the simulation validation test for validation, which resulted in the relative errors of the simulated repose angle and the measured repose angle of primary and secondary stems of pod pepper of 2.65% and 1.16%, respectively, which were less than 5%. The results show that the discrete element model construction approach and parameter calibration method for the pod pepper stems can be used to guide the construction of discrete element model and the parameter calibration for the dwarf-type plant stems.</p>
