Cooling Pipes

The design reasonability of cooling pipe greatly affects the quenching performance of hot stamping die. In this paper, rectangular box is the carrier, the parameters of cooling pipe section, such as the diameter of cooling pipe, the distance between cooling pipes, the distance between cooling pipes and die surface, were studied by numerical simulation and orthogonal experiments. The quenching uniformity was taken as the evaluation criterion during research. Finally, the optimal parameters about cooling pipes distributed in hot stamping die were obtained and the quenching uniformity was improved.

Reduction System

Nguyen Dong Anh, Khong Doan Dien and Nguyen Duy Chinh in [1] have studied the vibration of inverse pendulum system installed with the vibration reduction system TMD-D and DVA. These results implemented by numerical simulation for the articulated tower in the ocean show that the obtained oscillations in some cases with installed absorber increase the amplitude of vibration when compared to the case without absorber. It is a fact that when simulation is employed, the parameters of TMD-D and DVA are chosen arbitrarily without optimal design. In the paper, the authors investigate to find the optimal parameters of the TMD-D and DVA absorbers in order to optimally reduce the vibration for the inverse pendulum system. These research results are applied to reduce the vibration for the articulated tower in the ocean.

Main Component

In this paper we consider the structural and technological process of the combine used in the process of separate harvesting of grain crops, as well as a number of its parameters. Among the main units of the combine, we allocate a conveyor and devices for removing beveled stems from under the wheels of the vehicle. The principle of operation of the conveyor at different phases of the Reaper and especially the removal of cut stems from under the wheels of the vehicle during operation of the Reaper. The results of theoretical studies on the establishment of the optimal design of the parameters of the belt conveyor are presented, the ranges of their optimal values are considered and determined. Studies on the establishment of optimal parameters of the screw divider in the Reaper, which is the main component of the device for removal of beveled stems, are presented. Taking into account the optimal design and mode of operation of the screw divider, the correct work is provided to remove the cut stems from under the wheels of the harvester.
