Abstract Purpose Determining the safety conditions of a hot pepper harvester to mechanize harvesting. Methods The dynamic characteristics of a hot pepper harvester were analyzed with the dynamic simulation program RecurDyn. Results The pepper harvester can climb a maximal slope of 25° under full loading conditions; the maximal allowable height of an obstacle over which the harvester can drive is 450 mm; the minimal rotation radius during a spin turn is 870 mm. Conclusions Considering its dynamic characteristics, the harvester can be applied on over 95% of domestic upland fields. The safety accident rate can be decreased with the use of the spin turn method. In conclusion, the dynamic characteristics are sufficiently safe for the domestic upland fields.

Good Agreement

Soot formation and oxidation are important in the field of gas turbine combustion in as much as they affect the flame tube durability and the pollution problem. Therefore, an analytical model was designed and it is here developed further to increase its predictive capability. Results show very good agreement between the model and the measurements at both idle and full loading conditions.
