Determination of the vibration emission level for a chipper with combustion engine

Abstract

Abstract Presently, we observe an increase in automation and mechanization of many areas of life and industry, which allow to increase work efficiency and reduce costs. However, many circumstances such as terrain shape, forestation or urban planning can prevent the deliver and operation of various types of machinery. Consequently, an important area of development for the basics of machine construction is non-road machinery. The high mobility and relatively low own weight allow operation in the most adverse conditions. One of such machines are chippers for wood branches. They are usually driven by combustion engines, which means they emit pollutants in the fuel combustion process together with noise and vibrations. All the above factors can negatively affect both the machine operator and the environment. It is therefore justified to examine the possibility to reduce the emission level of harmful media. This paper presents the results of study involving the measurement of vibration and noise generated during operation of a chipper with combustion engine under various operating conditions. The presented results will allow to identify the scale and place of origin of vibrations. They can act as a source of practical guidelines for the design of machines of this type.
