In order to improve the performance of the shock isolation-type concrete breaker, this paper deals with the theoretical analysis and ist design. The shock isolation-type concrete breaker was recently developed to reduce the detrimental vibration or shock caused in portable crushing tools such as the concrete breaker. However, its performance was not as good as expected, since the theoretical approach was lacking in the design stage owing to a very complex mechanism. So, a new method for analyzing the concrete breaker which combines the signal-flow graph and the digital simulation technique in introduced. Based on the results of this analysis, a modified shock isolation-type concrete breaker is demonstrated and the crushing energy is increased to 130%, regardless of reduction of the vibration of the main body to 115 dB in VL value.
