The proposed research focuses on improving the operational efficiency of Vaderstad disk openers with optimized disk geometry and properly induced vibration applying on the disk openers. The objective of this study is to find the effect of major parameters related to the disk shape and induced vibration in it on: (1) change of the direction of friction force between the disk and soil, (2) elastic deformation of contact surface, and (3) change of friction coefficient.Factors such as: normal load on the paired surface, contact surface topology, direction of the vibration, amplitude/frequency of the induced vibration, and the cutting velocity will be modeled within a simulation environment first. Via conventional numerical optimization methods, the most influential factors will be identified and ranked. A lab-scale setup will be developed for hypothesis testing and evaluation. The experimental setup would consist of a vibrating cutting tool, a disk, and a compact-soil specimen, whose compactness, texture, and water content can be controlled.

拟议的研究重点是通过优化的磁盘几何形状提高Vaderstad磁盘开瓶器的运行效率，并适用于磁盘开瓶器上的振动。 The objective of this study is to find the effect of major parameters related to the disk shape and induced vibration in it on: (1) change of the direction of friction force between the disk and soil, (2) elastic deformation of contact surface, and (3) change of friction coefficient.Factors such as: normal load on the paired surface, contact surface topology, direction of the vibration, amplitude/frequency of the induced vibration, and the cutting速度将首先在模拟环境中建模。通过常规数值优化方法，将确定和排名最大的影响因素。将开发实验室规模的设置，用于假设检验和评估。实验设置将包括一个振动切割工具，磁盘和紧凑的土壤标本，其紧凑，质地和水含量可以控制。
