Balancer design for scroll compressors using vibration plane model

진동평면모델을 이용한 스크롤 압축기 균형추 설계

An effective balancing method for mil compressors is developed based on vibration plane model. By assuming the design range of balancer size is not large and considering only the radial axial direction rigid vibration of the mil compressors, we can find the vibration plane (V-plane) describing the vibration level of the scroll compressor depending upon balancer design specifications. By in the intersection of two minimum lines (areas) obtained from the couple of V-Planes we can find the design lesion to minimize vibration level of the compressor. The full design process is described by using an illustrative example with upper and lower balancer weights. Further more sensitivity analysis of parameters important for designation of size and positioning of the balancer is analyzed.
