Large diamond circular saw blade is a plane with large diameters and thin thick, so there are serious vibration problems in the process of sawing stone under the high-speed. By using the force hammer producing incentive experiment method, the effect of the inner and outer diameters to the vibration modal and frequency of diamond circular saw blade are analyzed. Through comparing inner and outer diameter, it can be found that the inner diameter has greater influence on the natural frequency, while the outer diameter has greater influence on the amplitude. The result supplies reliable data for eliminate or reduce resonance damage.

Thinner saw blades cannot resist large lateral cutting forces due to their lower stiffness. In this paper we propose a composite reinforcement method to improve the mechanical properties of circular saw blades. We analyze and simulate the stress and strain fields of our proposed reinforced circular saws by Finite element method. Our analytical results contain not only influences of reinforcing parameters but also loading conditions on the lateral stiffness and the natural frequency of composite saw blades. Here the reinforcing parameters include: 1) the reinforcement location on circular saw blades, 2) the volume fraction of the reinforcements, 3) the number of the reinforcements; and loading conditions include: 1) the cutting force, 2) the rotational speed. Our composite reinforcement model and simulation results can contribute to a better design of circular saw blades.

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.

Abstract Electromagnetic crimping is a solid state, high-speed, and high strain-rate joining process. Finite element analysis, as well as experimental study, was carried out on three types of field shapers, namely, tapered, taper-stepped, and stepped. In all three field shapers, the effective length, outer diameter, inner diameter, total length, and materials properties were constant. These field shapers were kept inside the same multi-turn solenoid coil for all the experiments. It was found that the taper-stepped field shaper results better regarding impact velocity, Lorentz force, temperature generation, less heating, and uniformity in crimping among the three types of field shapers.

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.

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.
