Title The structure design of a 2-degree-of-freedom manipulator used for noise measurement
Abstract
With the development of modern industry,a large number of machines come into people’s live. These devices bring great convenience to people’s daily life and work. However, noise emitted during operation not only produces great pollution on the environment, but also seriously affects people’s physical and mental health. Learning how to measure and control noise has become a topic of considerable interest.
This paper aims to analyze the existing noise measurement system according to research status of noise measurement and mechanical arms, and determine the overall scheme of structural design of a 2-degree-of-freedom manipulator used for noise measurement. At the same time, through analyzing the manipulator’s conventional working conditions within its range of motion, the paper selects the appropriate structure and components of the manipulator.Besides, by using the three-dimensional drawing software SolidWorks , the solid modeling and assembly of each part of the arm is finished, and the three-dimensional structure and two-dimensional drawings of the manipulator is made. Finally, the paper makes the finite analysis of the arm’s key components by utilizing the finite element analysis software SolidWorks SimulationXpress.
Keywords noise measurement, manipulator, structure , finite element analysis
