利用双自由度反共振原理设计的新型制样粉碎机 ,与传统单自由度系统制样粉碎机相比 ,具有激振电机不振动、没有陀螺效应、提高激振电机的使用寿命、改善工作环境、达到防震降噪目的的特点 同时由于激振能量大部分被振动料钵吸收 ,在相同情况下 ,电机功率由原来的 1 1kW降至 0 .5kW ,达到了降低能量的效果 Compared with the traditional single-degree-of-freedom system sample-making mill, the new sample-making mill designed by using the principle of two-degree-of-freedom anti-resonance has the advantages of not vibrating the motor and no gyro effect, improving the service life of the excitation motor and improving the working environment , To achieve the purpose of the characteristics of earthquake noise reduction At the same time as most of the vibration energy absorbed by the vibration bowl, under the same circumstances, the motor power from the original 11kW down to 0 .5kW, to reduce the energy effect
