无试重的动平衡技术的研究

摘要

平衡配重过程作为动平衡的一个重要步骤，会直接影响到动平衡的质量。探索了平衡配重与平衡量之间的关系，不平衡量与振动之间的关系。经理论分析与实验研究，导出了关于平衡配重的数学表达式。依据该式，机械仅停车一次，可实现无试重的动平衡。最后，在转子上随机增加不平衡量后，使用现场动平衡技术，对该结论进行了验证。%The counterweight process as an important step in dynamic balancing,will directly affect the quality of dynamic bal-ancing. The relationship between the counterweight and the amount of balance,the amount of unbalance and vibration were re-searched. The mathematical expression about the balance counterweight was obtained through experimental research and theoretical a-nalysis. Based on the formula,stopping only once,the dynamic balancing without trial weight could be realized. Finally,with the ro-tor randomly increased the amount of unbalance,by using field balancing technology,this conclusion is verified.
