Оценка вибраций в металлорежущих станках на основе линейного закона их распространения

Abstract

The possibility to evaluate vibrations in metalcutters is considered by using their simplest propagation law-linear law-is considered. A procedure of determining the coefficients of the linear model of vibration propagation is presented by the example of their propagation in metallcutter guides. The adequacy of the linear model for evaluating vibration propagation at a distance from the source of their appearance up to 1.2 m is shown by comparing the actual vibration parameters (by an example of vibration velocity) with the values found when using the vibration propagation linear law. The evaluation error of vibrations does not exceed 2.5%. This makes it possible to use the linear model of vibration propagation simplest compared with the exponential model, exponential-power model, and power model to predict vibrations, which is especially important for the manufacturing production preparation, when designing and modernizing metalcutters, and when evaluating environmental indices of the quality of manufacturing processes implemented using them.
