Abstract:

Rollers’angular velocity matching of rolling driven equal channel angular deformation technology was investigated numerically by using finite element code DEFORM-3D. The results show that as the angular velocity of primary feeding roller is constant, the rollers’ angular velocity matching had only small influences on effective strain and output velocity, but had significant influence on torque of feeding rollers. With the decrease of angular velocity ratio of primary feeding roller to secondary feeding roller from 1.37 to 0.073, the torque of feeding rollers tend to become uniform. It was foun

Abstract:

A liquid packaging machine produces liquid packaging bags from roll film by cooperatively controlling the vertical seal roller, horizontal seal roller, and cut roller. These rollers are driven separately by servomotors as a multi-axis servo mechanism. Positioning control on the moving film is essential to make bags of accurate size. To achieve accurate positioning without lowering productivity, we propose two control methods. One is a two-step velocity control of the horizontal seal roller. This method enables continuous and high speed production of bags of arbitrary size. The second is phase

Flow forming is one of the cold forming process which is used for hollow symmetrical shapes. In this paper, the forward flow forming process is simulated using the finite element method and its results are compared with the experimental process. The variation of thickness of the sample is examined by the ultrasonic tests for the five locations of the tubes. To simulate the process, the ABAQUS explicit is used.

The device incorporates a dual-spring floating pressure mechanism and preload adjustment mechanism to ensure the adaptive performance of conditioning rollers during alfalfa stem flattening. Based on the biological characteristics of alfalfa stems, a rigid–flexible coupling model between stems and the flattening and modulating device was established. Using the Discrete Element Method (DEM) and Multib

Abstract:

Sunflower threshing is one of the most interesting field processes for making the sunflower ready for seed handling, drying, cleaning and oil extraction. One of the biggest problems observed during the sunflower threshing process is the accumulation of threshed crop on the first third of the threshing roller and passing off some unthreshed parts of sunflower heads. To solve the aforementioned problem and optimize the efficiency of the sunflower threshing process, this research was focused on devising and testing a sunflower threshing machine with a close threshing box system equipped with a sc

Abstract:

There is a close relationship between cold ring rolling product quality and ring diameter growth rate in cold rolling process, but the technological parameters are main factors in influencing ring diameter growth. The paper used both numerical simulation and experimental verification to study the effect of the core roller speed and wide-diameter ratio on increment of ring diameter in cold rolling process of deep groove ball bearing inner ring. It is found that the core roller has greater influence on diameter growth, and the faster the feeding speed of core roller is , the greater the incremen

The distribution of maximum equivalent stress on hemp stalks at different roller speeds were scavenged by LS-PREPOST function. The stress and strain distributions of hemp stalk under the transversely even-distributed load are analyzed through ANSYS software. The results show that hemp decortication largely depended on the rotation speed of separation roller and the feeding rate. In addition, the failure degree of bast fiber, the maturity and the water content of the stalk, and the difference in mechanical properties and geometrical size should be also taken into account.

A new bending fracture principle is proposed for ear picking by simulating the process of manually breaking off corn cobs. Based on this, a new test device for corn ear picking was designed to obtain the relationship between the ear-picking rate and the rotational speed of the snapping rollers, as well as the feeding speed. A mechanical test was conducted on corn at two different harvesting stages. This proved that the tensile breaking force used in ear picking was considerably greater than that associated with bending fracture, regardless of whether it was silage or mature corn. Moreover, the
