Parts that come into contact with the soil are ones of the important energy consuming parts in tillage operations. In order to improve the research and development efficiency of tillage components, it is necessary to develop a performance test platform for tillage components with high interchangeability, convenience and comprehensive data collection. Therefore, a performance test platform for combined powered and passive tillage components was designed. Strength analysis and structural design optimization of key components was based on ANSYS. A real-time measurement and control software was developed based on LabVIEW platform. The related tests results show that the test platform can be used to simulate the actual condition and meet the test requirements.

Force Compensation

This paper is on the development of a Direct Drive servo Valve (DDV) with flow force compensated spool. In valves with spool, flow force is caused by the unbalance of pressure exerted on each land of spool when high-speed flow passes through very narrow orifices. A simple method for flow force compensation using a stepped spool is presented in this paper. It is easy to manufacture the stepped spool of the presented method because the shape of it is simple. The method has another merit that the size of valve need not be increased. Actuating force required for driving the spool can be decreased through the compensation of flow force. The effectiveness of the proposed method is predicted through CFD analysis. The results of the CFD analysis are also utilized for the optimization of step shape. Prototypes of flow force compensated DDV are manufactured and the measurements of flow force are carried out. The measured effectiveness of flow force compensation is very similar to that from the CFD analysis. Performance test results of prototype DDV satisfy required specifications.

Flow Rate Control

This paper considers the feasibility of a new type of voice coil motor direct drive flow control servo valve. The proposed servo valve controls the flow rate using only a direct measurement of the spool position. A neural network is used to estimate the flow rate based on the spool position, velocity and coil current. The estimated flow rate is fed back to a closed loop controller. The feasibility of the concept is established using simulation techniques only at this point. All results are validated by computer co-simulation using AMESim and Simulink. A simulated model of a VCM-DDV (Voice Coil Motor-Direct Drive Valve) and hydraulic test circuit are built in an AMESim environment. A virtual digital controller is developed in a Simulink environment in which the feedback signals are received from the AMESim model; the controller outputs are sent to the VCM-DDV model in AMESim (by interfacing between these two simulation packages). A LQR (Linear Quadratic Regulator) state feedback and nonlinear compensator controller for spool position tracking is considered as this is the first step for flow control. A flow rate control loop is subsequently included via a neural network flow rate estimator. Simulation results show that this method could control the flow rate to an acceptable degree of precision, but only at low frequencies. This kind of valve can find usage in open loop hydraulic velocity control in many industrial applications.
