The mechanization of the whole process of sugarcane harvesting is an integral part of reducing the cost of sugarcane production. In order to select sugarcane strains suitable for mechanized harvesting, in this experiment, a dynamic resistance strain gauge and other equipment determined the related mechanical property parameters such as density, elastic modulus, and Poisson's ratio of different sugarcane varieties. Ansys/ explicit dynamics were used to establish a finite element model of the disc cutting device and to simulate the forces exerted on the stalk during sugarcane harvesting and also the quality of the cut section. Then, after obtaining the regression equation analysis and the response surface through the cross-section mass, the field harvesting experiment verifies the simulation results. The results show that the density, elastic modulus, and Poisson's ratio significantly affect the cutting quality within the three types of mechanical parameters. Through response surface analysis, when the elastic modulus is 92 MPa, the density is 1145 kg m -3 , the Poisson's ratio is 0.404, the best cutting quality was obtained, and the section flatness is 57.09%. According to the cross-sectional regression equation, the calculation results are as follows: Liucheng 05-136 > Yuetang 94-128 > Guitang 42, which is the same as the actual harvest quality results under the two planting modes. This indicated that the difference in the mechanical properties of the sugarcane would significantly affect the quality of mechanical harvesting, which provides a reference direction for selecting sugarcane varieties suitable for mechanized harvesting.K e y w o r d s: elastic modulus, Poisson's ratio, mechanized harvesting, finite element

Gao et al [28] and Allameh et al [31] toke cutting speed, wedge angle and slip cutting angle as experimental factors to obtain the minimum unsupported cutting power consumption. Hou et al [32] obtained the optimal blade parameters (blade angle 14.06°, slip angle 19.93° and cutter head inclination angle 10.54°) through finite element model and response surface analysis.…”

In order to reduce the labor intensity and improve the efficiency of pruning, this study designed a multi-section luffing apple pruning equipment suitable for apple orchards in hilly and mountainous areas of China. In the essay, the structure and working principle of the equipment are expounded, the cutter was analyzed, and the parameters were determined. Using the self-made test bench to simulate the field experiment, this study selected the ratio of cutting speed to feeding speed and feeding speed as the influencing factors and took the cut-off rate, cutting efficiency and cutting power as the objectives to carry out single factor experiment and quadratic regression orthogonal experiment. The test results show that the cutting power increases with the increase of ratio of cutting speed to feeding speed, and the cut-off rate and cutting efficiency first increase and then decrease. As the feeding speed increases, the cutting efficiency and power increase, and the cut-off rate decreases. When the cutoff rate was greater than 80%, the optimal combination of operating parameters was the feeding speed of 0.55 m/s and ratio of cutting speed to feeding speed of 1.29. Under this combination, the cut-off rate was 84.9%, the cutting efficiency was 13.1, and the cutting power was 175.7 W. The error between the predicted target value of the model and the average measured target value was less than 7%, so the test results are reliable. According to the obtained optimal operating parameters, the actual cutting experiment of the pruning equipment in the field was carried out, and the cutting rate was 96.3%, which meet the design requirements. This study can also meet the needs of mechanized pruning of fruit trees with different crown shapes, improve the applicability of pruning equipment, and provide support for the development of mechanized pruning equipment in China.

“…Studies stated the cutting location (node/internode) and number of stems (crop density) are also key factors in determining the optimal cutting force and energy requirements during harvesting (Chandio et al., 2013; Y. Chen et al., 2004; Hemmatian et al., 2012; Muzamil et al., 2016; Oka et al., 2014; Yore et al., 2002; Zareiforoush et al., 2010).

A device was developed for on‐field cutting energy measurement of cereal crops. Physical, engineering, and anatomical properties of prominent rice (Oryza sativa L.) cultivars of India were studied at different stem positions using a factorial CRD design. The effects of changes in different operational parameters, including blade bevel angle (15°, 20°, and 25°), cutting angle (25°, 30°, and 35°) and cutting velocity (2.9, 3.44, and 4.1 m s−1) on cutting force and cutting energy of rice stalk were also studied. Cutting angle indicated the angle of inclination of cutting edge to the horizontal at blade‐crop interface. The assessment of these properties and parameters in relation to crop cutting energy, led to the development of a smart device for energy measurement up to a size of three skills. This device consisted of a compression system, crop holding unit, cutting unit, and sensors to measure the force, speed, and cutting height. The device's measurement abilities were evaluated with wheat (Triticum aestivum L.) stalks at different cutting speeds (0.83, 1.16, and 1.5 m s−1 and stem heights (10, 20, and 30 cm from ground). Values for cutting force and energy ranged from 1.85 to 1.45 N and 10.81 to 8.48 N mm–1, respectively. At all stem heights, the cutting force and cutting energy ranged from 1.79 to 1.44 N and 11.92 to 6.74 N mm–1, respectively. The ultrasonic sensor provided real time cutting height data with an accuracy of 97.5%, while the gyroscope sensor had an accuracy of 94.29% for on‐field cutting angle measurement.
