Vibration Characteristic Analysis of Welding Point Based on the Loss Factor of Rotary Compressor
نویسنده
چکیده
The overall aim of this paper is to determine optimum position of welding point and number of spot welding in the structure to obtain good characteristics of vibration and noise. For this purpose, two kinds of loss factor were adopted. One is loss factor of sub structure, another is structural loss factor based on the complex welded or assembled structure. Using these two parameters, it is possible to derive the coupling loss factor which represent characteristic condition of welding point behavior of vibration. Coupling loss factor of welded condition in complex structure has been derived by using Statistical Energy Analysis (SEA). The derived equation for a coupling loss factor has been simplified on the assumption of weak coupling between two welding sub structures. Finally it shows some experimental results based on the proposed equation.

Vibration Analysis of an Air Compressor Based on a Hypocycloidal Mechanism: an Experimental Study
In this paper, the experimental vibration analysis of a single cylinder air compressor based on a hypocycloid straight line mechanism (HSM) is investigated. The HSM mechanism uses planetary gears to convert rotational motion to purely linear motion. In the conventional air compressor, the slider- crank mechanism is replaced by the HSM mechanism with appropriate counterweights. The constructed s...

Piping vibration which is mainly caused by the torsional vibration of rotary compressor can be a major noise source of air-conditioner. Especially, the tangential vibration of rotary compressor which is due to the torsional vibration is much higher than the radial vibration or the vertical vibration of compressor. A study as to how the tangential vibration of rotary compressor is related with t...

Sanyo has originally introduced 6HP two-cylinder rotary compressors for packaged airconditioners in I 985. The concept of two-cylinder rotary compressor has been recently applied to room airconditioners(RACs) for the purpose of reducing vibration and noise of the unit. However. RACs are demanded to decrease the noise by lowering levels of the compressor noise. SanYo has newly developed the quie...

In this study, operation of compressor station has been investigated by exergy approach. Exergy analysis is a thermodynamic method which shows the irreversibility of a system quantitatively. Gas compressors are used to compensate the pressure drop along the gas pipeline significantly. The compression process causes temperature rise of gas; in this regard gas cooler is applied to reduce the temp...
