A dynamic model of antiresonance horizontal vibration centrifuge was established under the condition of linearly-variable mass. The effect of linearly-variable mass on the amplitude response curve of the vibration centrifuge was investigated. Results showed that the amplitude of upper body and lower body increased (or reduced) linearly with the increase (or reduce) of the mass load, and the amplitude of lower body would increase as the reduce range of mass load was too big.%建立了物料质量线性变化的反共振卧式振动离心机动力学模型,分析了物料质量线性变化对机器振幅的影响规律。结果表明:物料质量线性增加(或减少)时,上、下质体的振幅都会增加(或减少);当物料质量减少幅度较大时,下质体振幅反而会增加。
