Machine Systems for Biomass Harvesting and Processing
Dr. Liu’s research in this area focuses on (1) testing mechanical properties of dedicated energy crops; (2) studying field efficiency and capacity of different machine systems for biomass feedstocks harvesting and processing; and (3) modeling biomass feedstocks logistics systems.
Machinery for Specialty Crop Production
The cultivation and harvest of specialty crops for the fresh fruit market are labor intensive. Dr. Liu’s research activities in this area include innovative technologies and equipment development for: (1)and (2) .
Agricultural production related off-road equipment is another area of interest. Dr. Liu’s interested topics include: soil compaction and relevant environmental issues, tillage and soil and water conservation, power performance, tractive efficiency and fuel consumption of off-road power units.
