Physical Properties of Agricultural Materials
Firmness and maturity testing of fruit and vegetables
Nondestructive acoustic classification and quality control of high-value agricultural commodities has been the subject of theoretical and experimental studies since 1989, in collaboration with Prof. N. Galili of the Agricultural Engineering Department, Technion. A new piezoelectric sensor and inspection method was developed for frequency response analysis and detection of whole fruit and vegetable properties. The research was initiated with the support of the Israel Ministry of Agriculture (1993) and BARD, Israel - U.S. Binational R&D program, in collaboration with Prof. R. Rohrbach of North Carolina State University (1994-97). The first experimental setup showed the capability of measuring fruit response to mechanical impulse and of evaluating fruit firmness nondestructively. A research project was established with Eshet Eilon - Agro-Industrial Systems, Ltd. for further development of the method as an automatic firmness-sorting machine (1995-97) and recently with Sinclair International. The project is supported by the Israel Ministry of Industry and Commerce R&D program and the Organization of Fruit Growers in Israel.
This work was the subject of one PhD. and three M.Sc. theses. Results were presented at two workshops and at several international conferences. The present state of the work is summarized in 8 professional publications and 4 technical reports. The piezoelectric sensor and the inspection method were the subject of a Technion Innovation Prize and an application for a patent worldwide.
Other methods for sensing material properties
A research program was developed to monitor the soil surface level, through foliage, by microwave technology. The first stage of the program, entitled “Ground surface sensing through plant foliage”, was performed as a BARD project with Prof. R. Dodd of Clemson University, South Carolina. The second stage included the development of a prototype, in collaboration with the Israeli Industry (Elta, Ltd.). Simultaneously, a more fundamental study on the subject was being conducted by a D.Sc. student. The present state of the work is summarized in 2 professional publications. Another research study on detecting the composition of agricultural fluid products by near infrared (NIR) and (Mid-NIR) spectroscopy has been initiated .
Soil/machine interaction laboratory
Various research projects on soil-machine and soil/wheel interaction were performed in the General ADAM Soil/Machine Interaction Laboratory, Faculty of Agricultural Engineering, Technion, in collaboration with Prof. Dan Wolf. The laboratory is unique in its magnitude and capacity, and enables fully controlled studies of soil/machine interaction research under one roof. At the heart of the laboratory are two large soil bins (80 m long, 4.7 m wide and 2 m deep) containing four soil types. A heavy power dynamometer carriage pulls, pushes, revolves, controls and transmits mechanical or hydraulic power to the tested elements, operating on top or within the soil. Special reconditioning methods were developed, for breaking up, pulverizing, wetting, compacting and shaping of the soil. Research activities in the laboratory include the study of mechanical soil properties under various loading conditions, soil/wheel interaction, vehicle mobility and soil pressure distribution, which are performed mainly for the Ministry of Defense.
In-situ soil and soil/tire interaction tests
A special single-wheel field testing device - the Technion Wheel Tester (TWT) - was developed as part of a joint research project with Prof. S. Upadhyaya of Davis, California. The project dealt with traction vs. compaction performances of off-road tires. The TWT was based on a 4x4 heavy-weight hydraulic-powered tractor, capable of performing in-situ penetration and shear soil tests. The TWT system allowed full-range testing of agricultural and cross-country tires. It covered the three modes of tire rolling conditions: towed mode, self-propelled mode and driving mode. The TWT, together with a special device for measuring tire stiffness, was used in research on new tire performances, in collaboration with Alliance - Israel Tire Industry and the Israel Ministry of Defense. The work in this area was the subject of one PhD. Results were presented at several international conferences. The present state of the work is summarized in 3 professional publications and 4 reports.
Automation of field machinery
A research project was conducted with Prof. W. LePori of Texas A&M University (supported by BARD), in order to improve energy efficiency and automation of field machinery. This project included navigation of field machinery by means of laser beams and control of a multi-jointed mobile truss system. The project was summarized in 4 professional publications .
Soil-Underground Structure Interaction
Development of the research laboratory for investigating soil/structure (pipe) was a joint project with Prof. N. Galili. The laboratory contains experimental, analytic and numerical tools, and is used for graduate research and for consulting on soil/pipe interaction projects. It provides services to Israeli industry and to the following companies abroad: Veroc and Hobas in Europe, and Owens Corning Fiberglass in the USA. The primary research achievement was improvement of the predictive capability of soil/pipe interactive behavior in a wide range of stiffness ratios of soil and pipe. The research in this area was the subject of two Doctoral studies and a prestigious R&D Technion prize (1987). Results were summarized in 6 papers in scientific journals, 4 papers at international conferences and 21 research reports. The major research activities in this area are listed below.
Soil/pipe interaction of semi-rigid and flexible pipes (1977 - to-date)
Soil/pipe interaction studies of pipes, up to 1.20 m in diameter, buried in different soils and various laying conditions, were conducted under surcharge pressure of up to 200 kN/m2. Sensory and data acquisition systems were developed to monitor normal and tangential soil stresses in the soil/pipe interface, strains in the pipe wall, radial deflections of the pipe and soil stresses at different locations in the soil-bin. Short-and long-term soil/pipe interaction tests at different laying conditions were analyzed by a refined analytical model and by customized or commercial computer programs.
Two long-term research projects were performed on semi-rigid AC pipes (1977-81) and flexible FRP pipes (1983-85) for the international community. An additional two-year study was made on the buckling of a flexible pipe under negative pressure conditions (1985-87). The experimental work on large-diameter pipes of different soil/pipe stiffness ratios and laying conditions provided the basic database for an ISO task group and for an AC pipe group. Similar work on FRP pipes, produced by different international manufacturers, provided experimental data for the ISO committee to update their standards and laying condition recommendations for large-diameter FRP pipes. The soil/pipe studies were the subject of one Doctoral thesis.
Sea water conduit for the main cooling system of Eshkol (1978-80), David (1990-92) and Ashkelon (1996-97) electric power stations
The first large-diameter fiberglass-reinforced plastic (FRP) sea water conduit, designed for the cooling system of power stations in Israel, was constructed in Eshkol-C Power-Station in 1978. A Technion team (Dr. Galili, Dr. Shmulevich and Prof. O. Ishai) - participated in all R&D aspects of design, production, erection and testing of the new conduit. Following the success of the initial project, the FRP pipe option was selected for the David Power Station, Units 2 and 3 (1990-92) and the Ashkelon Unit (1996-97). The Technion team rejoined the design group from the Power Station Division for inspection of the design, control of manufacturing and laying conditions, and testing of the pipeline; to include long-term failure tests for lifetime prediction of the underground large-diameter FRP flexible pipes.
