Through piping model test and pump unit trial it is shown that with the two types of isolating shims the vibration acceleration of the piping system can be reduced evidently.
经管路模型试验和水泵机组试验证明，这两种隔振垫可使管路系统振动加速度级明显下降。

The system can simulate the executive process of nc programme files, and realize the simulation of speed and acceleration curve, and process time and distance with the unit of controlling period.
Relationship between the linear acceleration and the resonant frequency of the sensing unit was deduced and the finite element method was used to simulate the correctness of the theory.
