At present, our country has stepped up efforts to develop biomass power generation. However, due to the mill not in-depth study of cutting forces and factors in the design of branches crusher which led to the branches crusher can not meet domestic branches of biomass power generation’s demand to raw materials. In the article, the cutting force of the branches grinding has been studied based on BX218 branches crusher. The formula for calculating the cutting force has been deduced.

Abstract In orthopedic surgery, bone cutting is an indispensable procedure followed by the surgeons to treat the fractured and fragmented bones. Because of the unsuitable parameter values used in the cutting processes, micro crack, fragmentation, and thermal osteonecrosis of bone are observed. Therefore, prediction of suitable cutting force is essential to subtract the bone without any adverse effect. In this study, the Cowper-Symonds model for bovine bone was developed for the first time. Then the developed model was coupled with the finite element analysis to predict the cutting force. To determine the model constants, tensile tests with different strain rates (10−5/s, 10−4/s, 10−3/s, and 1/s) were conducted on the cortical bone specimens. The developed material model was implemented in the bone cutting simulation and validated with the experiments.

This paper studies the force and deformation of the connecting channel in Ningbo rail transit construction, which firstly used the mechanical shield method. Steel-concrete composite structural segments are used in the T-joint of connecting channel. The cutting part of the segments are replaced by the concrete and fiberglass instead of reinforced concrete. Basing on a variety of three-dimensional design software and ABAQUS finite element analysis software, a refined finite element analysis model of the special segments is established. By considering the influence of curved joint bolts, the force analysis of the special segments under the structural state before and after construction is performed. According to the analysis and comparison of the deformation of the segments with and without the bolts, it is concluded that the steel-concrete segments can withstand the pressure of the soil before and after the construction. Suggestions for the safety of the design and construction of the segments are put forward.

The Finite Element Analysis

In the traditional designs of milling cutter, we cannot get the required accuracy of machining as there may be local deformation on the edges, even more the cutter can break down. Aiming at this situation, a finite-element model of straight pin milling cutter with helical tooth are built using Marc, a nonlinear finite-element analysis software, the different cutting forces of the milling cutter during the cutting process are analyzed and the cutting forces of the milling cutter at different parameters are studied. We get the stress, the strain and the temperature distribution of the milling cutter in different situation. Our work offer a theoretical basis of improving stress of the cutter, designing the structure of cutters reasonably and analyzing the cutter failure as well as a new method of analysis and calculation of the cutter life and strength.

Data Processing Methods

In this paper, the turning process of 45# steel was simulated and analyzed based on the metal cutting finite element analysis software DEFORM-3D. The analysis result of cutting force was gained. However, due to some reasons of the software itself, there is noise data in analysis results. Thus, it’s needed to filter the data to extract useful information. The selected short-duration and steady-state cutting force data was processed with the use of six-sigma rule through mathematical statistics analysis. As a result, some bad data were rejected. Noise data was filtered out via wavelet analysis and the processed function curve of cutting force that changes with time during the whole cutting course was gained.
