Abstract

The present invention is related to at least one vibration measurement sensor (3) adapted to measure the vibrations formed on a test object (0) with moving mechanical systems, at least one noise measurement sensor (4) adapted to measure sound intensity and/or particle velocity and/or sound pressure in at least one direction, i.e. on one axis, and a vibration and noise mapping system (1) that is adapted to control the vibration measurement sensor (3) and the noise measurement sensor (4), to provide the vibration and acoustic performance data of the test object (0) according to the data obtainedfrom these units (3, 4) and to identify the areas on the test object (0) that are problematic or need to be studied further in order to improve vibration and acoustic performances thereof, and to control the operation of test objects (0) such as moving mechanical systems under different conditions.

Description

technical field [0001] The present invention relates to a compact system and method for vibration and noise mapping that facilitates generation of vibration and noise maps of vibration and noise sources and rapid identification of areas requiring improvement and / or problematic. Background technique [0002] Dynamic mechanical systems, such as motors used in automobiles or household appliances, vibrate and generate noise due to their moving parts. However, both vibration and noise have physiological and psychological effects and have a direct impact on human health. Consequently, the vibration and acoustic performance of mechanical systems has become one of the most important parameters affecting customer satisfaction in recent years. Vibration and acoustic performance is measured in an anechoic and / or reverberant chamber. [0003] In cases where vibration and acoustic performance do not meet target values, the methods used to identify and resolve the problem are briefly de...
