Modal Analysis of a Electric Tool

Abstract:

People have paid more and more attention to green production and environmental protection along with the gradually improved of the productivity level and the increasing of the production conditions. As the widely used of the hand-held electric tools like electric angle grinder and electric drill in the daily production, the environment around will be influent by the vibration and noise of the surface of the electric tool when using the electric tools .Therefore, it is very important to analyze the vibration performance of the whole electric tool. In this paper, the finite element method is used for modal analysis. A vibration response experiment of the same electric tool working under no-loading condition is done to obtain the time-history acceleration response. A conclusion is obtained that the first order natural modal and the fifth order natural modal are motivated when electric tool working under no-loading condition.
