During the sawing process of cold sawing machine, it emergences of blade wear too fast, the current is too large, sawing not high quality of rolled products,Be aimed at those problem, the paper established the finite element of side shake structure saw blade and ordinary flat blade model, and using the ANSYS finite element analysis software to make the dynamics calculation about the two kinds of saw blade. Through the analysis and comparison of backlash saw blade and natural frequency, different cutting parameters effect of stress and deformation of the saw tooth transient, and the simulation results will be applied to the field of sawing testsThe results show that the backlash saw blade in the vibration characteristics, performance and other aspects of the force and deformation are improved compared with the ordinary blade

Three kind of diamond circular saw blade with different structure parameters are designed in this paper. Adopted single-factor test, sawing force and vibration are measured by cutting several kinds of strength concrete in different cutting parameters. The analysis to characters of sawing force and vibration helps to find out optimum structure of diamond saw blade with different segment width, more rational sawing parameter and its adaptability to workpiece material.

The finite element method was used to study tangential roller method impact on the stability of circular saw blade. Using 30 ° cyclic symmetric model is analyzed. The results show that the tension of the saw blade is not the same, and tensioning effect is different, when the tangential roller pressure is not same. At the same time, after tangential roller, the face run out of saw blade is small, which show that the smoothness of tangential roller is better.

To analyze the stress state of seed cotton in the process of cotton ginning and to improve the quality of lint, a new model for cotton, the laminated cotton model, is presented based on the idea of a composite laminate. The model assumes the cotton mass is made up of a certain number of cotton fibers, each of which has a different arrangement angle. Based on this model, the ginning process is simulated using finite element analysis. The mechanical properties of a single cotton fiber that is either machine- or hand-picked are obtained. The working condition of the ginning process is described successfully. By analyzing the influence of different working conditions on the serration cotton ginning process, the simulation results show the model prediction is reasonably consistent with existing experiments. For example, to improve the productivity and quality of lint, it is important to guarantee the saw teeth are sharp and smooth, with none being crooked or inverted, and missing teeth on each saw blade should not exceed the specified value.

The finite element modal analysis was used to study natural frequency of circular saw blade, when slotted. Finding the frequency of slotted is smaller than no slotted saw blade, showing that slot can have the effect of noise attenuation. The increasing of slot length, slot width, slot position, slot number can reduce the natural frequency of circular saw blade on the whole. The orthogonal text was used to study slot parameters. Finding that slot parameters’ influence of primary and secondary relations on saw blade first five natural frequency is slot position > slot number> slot length > slot width.

To improve the performance of diamond saw blade sawing, reduce vibration at the time of its work, prevent the blade resonance, the parametric model of diamond saw blade was been established based on the finite element software ANSYS, and the analysis file was been established through the structural reliability analysis module of the finite element analysis software ANSYS. The finite element method combined with the Monte Carlo method can be used to get the sensitivity index which effect the diamond saw blade security and the probability distribution function and the other principal impact factors, and which is theoretical basis for the diamond saw blade optimization and design.

Effect of thermal modification temperature of spruce wood on cutting parameters during circular saw blade cutting. The work examines the effect of temperature on energetical parameters (specific cutting resistance and cutting force) when cutting heat-treated wood of Norway spruce (Picea Abies) by a circular saw. The test samples were heat-treated at 160°C, 180°C, 200°C and 220°C. One sample was not heat treated and was used as a reference sample. In comparison with the theoretical assumptions, the influence of temperature on the cutting force and specific cutting resistance was confirmed. With increasing temperature of modification, the specific cutting resistance and cutting force decreased. The reduction of value of cutting force is related to changes in the chemical structure of the wood components, weight and density loss due to the increasing temperature of modification.

In this paper, Finite Element Analysis (FEA) used DEFORMTM 3D to construct 6061 aluminum sawing simulation. Before sawing, we pushed the speed and cutting speed under pressure as a sawing process parameters. Then there are three groups of combination conditions in the study. Analysis and discussion based on loading, effective stress, cutting temperature and blade wear. According to the impact parameters the structural design of the saw blade is improved by taking full account of the mutual influence of sawing parameters.

A nonlinear numerical simulation model of stone-cutting circular saw blade was developed for the purpose of understanding the mechanics of cutting process by employing LS-DYNA program. Based on the classical damage model theory and fracture criterion, the action of cutting stone is mainly considered as extruding sliding friction and pressing. The movement rule and wear mechanism were analyzed in stone cutting process. After the transient strain field was obtained, the corresponding pressure was calculated. The results showed the present method is applicable to forecasting and optimizing the cutting parameters for efficient control and improvement of separation.

The effects of cutting parameters on the transverse vibration of diamond circular saw blade were experimentally investigated. Transverse vibration was online measured by a novel measuring system developed by wireless sensor. Meanwhile, axial force on saw blade was measured by a dynamometer. By the experimental results under different cutting parameters, the time domain characteristics of transverse vibration of saw blade were analyzed, and the relationships between transverse vibration and cutting parameters were also obtained. Axial deformation is greatly influenced by the axial force acting on saw blade.

We investigate the natural frequency and the amplitude of circular saw blades during idling. We use four blades in the paper: 1) The traditional circular saw blades, 2) The circular saw blade with damping materials which is distributed in the core of blade, and the circular saw blade has a uniform thickness, 3) Similar to the above one but the circular saw blade has a non-uniform thickness, the damping region is thicker than other region of the circular blade, 4) the circular saw blade with damping material which is distributed around the core of blade by four small circular regions. We adopt the Finite Element Method in our numerical analysis. Our analytical results are very useful for a better design of circular saw blades.
