“…The planting distances of the transplanter have a total of ten gear stages from 26 to 80 cm, and the planting depths have a total of ten gear stages from 85 to 136 mm. The planting distance is the length between the transplanted seedlings, and the planting depth is the length between the depth of the planted seedlings and the soil surface [4,5,7,15] . The power of the transplanter is divided into the driving shaft and PTO through a belt pulley, as shown in Figure 1.…”

“…A vegetable transplanter is mainly used in an upland field, the environmental conditions of which are harsh including hard soil, gravel, and stone. A transplanter has various working conditions in terms of the planting depth and planting distance, and different combinations of the planting depth and planting distance are used to provide suitable planting conditions depending on the crop type and field conditions [4][5][6] . Because the planting distance and planting depth determine the rotational cycle of the transplanter power take off (PTO) and depth of the penetration of the transplanter hopper, respectively, the planting distance and planting depth affect the fatigue life and durability of the transplanter [4] .…”

“…Lee et al [14] measured and analyzed the torque load acting on the PTO shaft of a 75 kW agricultural tractor according to the gear selection during a rotary tillage and baler operation in Korean upland fields. Most studies on a transplanter have focused on the development of a planting device such as a hopper [15][16][17] , control of the transplanting part [18] , and a load data analysis according to the operating conditions of the transplanter [4,5] . Lim et al [5] developed an electric transplanter by replacing its engine-driven system with an electric motor-driven system, and measured the current according to the planting distance to provide useful information for the optimal design of an electric drive system.…”

The aim of this study was to analyze the effects of the planting distance and depth on the power takeoff (PTO) load spectrum of a small riding-type transplanter for the optimal design of the transplanter. To measure load data during actual planting operation, a load measurement system was developed using a torque sensor, a data acquisition system, and an inverter. Field experiments were conducted at four planting distances (26 cm, 35 cm, 43 cm, and 80 cm) and three planting depths (85 mm, 105 mm, and 136 mm) in a field with similar soil conditions. The measured load data were inverted into a load spectrum using rain-flow counting and Smith-Watson-Topper (SWT) methods. The safety factor of a transplanter according to the planting conditions was analyzed using the converted load spectrum and commercial software. The load spectrum for all planting conditions showed torque ratios similar within a high cycle region of 10 8 to 10 9. The torque ratio increased when the planting depth increased and planting distance decreased in the low cycle region under less than 10 8 cycles. The safety factors of the PTO driving gear and the driven gear increased as the planting distance increased at all planting depths. When the planting depth decreased at the same planting distance, the safety factor of the PTO gears increased. The results of this study might provide useful information for a transplanter PTO design considering the working load according to the various planting conditions.

“…Under an electric input powered by external voltage sources, they can reveal high elongation, high energy density, and large deformation [ 11 , 12 , 13 ]. In particular, the Ionic polymer–metal composite (IPMC) is an electroactive and thin membrane coated with a noble metal, usually PMCs are composed of an ionic polymer such as Nafion or Flemion, chemically plated or physically coated with platinum or gold conductors [ 10 , 14 , 15 , 16 , 17 ]. On the other hand, the action of IPMC materials is caused by the movement of ions inside the polymer at low voltages [ 9 , 18 , 19 ].…”

The polymer technology based on Electroactive polymers and metal composite ionic polymer has great potential and advantages in many engineering fields. In this paper, a laboratory stand for testing Ionic polymer–metal composites (IPMC) is presented. The laboratory station includes a power supply system and a measuring system for the displacement of IPMC composites. Tests and measurements are carried out using a laser transducer and a camera equipped with image analysis software to determine the IPMC strips displacement. The experimental investigation of IPMCs under different voltage supplies and waveforms, environmental working humidity conditions, temperature, and loading conditions has proved the significant influence of geometric dimension and the effect of increased stress on the displacement value. For materials powered by a higher voltage value, an increased deflection value was noted. In case of displacement, longer is the sample, higher is the displacement value. The length of the sample under load, affects adversely its performance,resulting in an increase in the load on the sample. For samples of a thick size, a more stable movement with and without load can be noticed.
