摘　　要：为明确当前用于铸造机匣复杂型腔抛磨的振动装置可加负载范围以及解决对大型机匣加工效果差、效率低的问题,建立了双机反向旋转的单质体振动系统同步力学模型,基于Simulink利用数值仿真论证了系统响应解的有效性。通过数值计算并以振幅为评判标准确定了可加负载上限,分析了不同负载下振动频率、激振力及弹簧刚度对振幅的影响,提出了面向大型机匣加工的设备改进策略。采用低通滤波处理了实验测得的振动装置加速度信号,验证了数值计算与仿真的正确性。In order to clarify the machinable load range of the machine currently used for vibratory finishing of complex cavity in casting casing and to solve the problems of poor effect and low efficiency when processing large casings,a kind of vibration synchronization mechanical model ofsingle-mass vibratingmachine driven by two exciters in reverse rotation is established,the validity of the system response solution is demonstrated by numerical simulation based on Simulink.Taking the amplitude as the evaluation standard and the effective load range is determined by numerical calculation.At the same time,the influences of vibration frequency,exciting force and spring stiffness on the amplitude under different loads are analyzed,and the methods to improve the system's amplitude for the machining of large casings are given.Finally,the acceleration signal of the vibratory device measured by the experiment is processed by low-pass filtering,which verify the correctness of the numerical calculation and simulation.
