A self-standing support has been developed with the aim of developing a compressor that can operate in a low rotation range. It was considered that the drive unit in the shell deviates from the equilibrium position when disturbance is applied to the compressor because it was supported by a spherical surface. In order to improve the practicability of the compressor that applies the self-standing support, the supporting method was examined to prevent the drive unit from slipping from the equilibrium position. First, a one point support, a two points support, and a four points support is proposed for simple models, and verified their effectiveness. As a result, it was confirmed that the four points support was the best support since the vibration transmitted from the drive unit to the plate was small and the drive unit can maintain its original equilibrium position even when an impact force is applied. Next, a five points support similar to the four points support was applied to the prototype of self-standing support, and it was verified whether the same results as the simple model could be obtained. As a result, it was revealed that the vibration transmitted from the drive unit to the plate was small, and the drive unit could maintain its original equilibrium position even if an impact force was applied. Therefore, it can be said that the five points support is effective for a compressor.
