Composite Reinforcement

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.

Noise And Vibration Reduction

Industrial noise and vibration leads to the workers disease, fatigue breakdown of pipeline and apparatus junction, decreasing of machine operating characteristics etc. According to statistics, amblyacousia and vibration illness takes the first places among all the other professional diseases. Investigations of noise and vibration levels at the operator's positions of "Volgoelectromontazh-1" Joint Stock Company of Russian Federation were done. Measurements were carried out according to existing methods and standards. In total 27 operator's positions were investigated in the main building and in the shop of consumer goods. The results of measurements showed, that for some positions (pendulum saw, cutting-off lathe, presses etc.) there were significant excesses of the sanitary standards of noise levels. Complex of measures of noise reduction was developed, including technical decisions and organizing measures. Results of measures implementation shows good efficiency of noise and vibration reduction.
