振动机械已在铸造生产中得到日益广泛地应用,振动电机作为产生激振力的动力源已开始采用。从发展趋势看,由于振动电机式激振器的技术经济指标先进,它将取代电磁式和机械偏心式激振器。因此,关于振动电机的系列参数、使用寿命和性能测试等问题,引起振动机械设计人员的普遍关注。在“惯性振动落砂机动态参数分析”课题的试验装置上,使用了两台公称激振力为6600公斤力、4千瓦的ZDS52—6型三相异步振动电机。该电机双轴伸、四偏心块、安装角可调。由于电机偏心块质量和几何形状的制造误
Vibration machinery has been increasingly used in foundry production. Vibration motors have been used as the power source for generating exciting force. From the development trend, due to vibration motor-type exciter technical and economic indicators of advanced, it will replace the electromagnetic and mechanical eccentric exciter. Therefore, the vibration motor on the series of parameters, service life and performance testing and other issues, causing vibration mechanical designers widespread concern. In the “inertial vibration falling sand machine dynamic parameter analysis” test device, using two nominal excitation force of 6600 kg, 4 kW ZDS52-6 three-phase asynchronous vibration motor. The motor biaxial stretch, four eccentric block, adjustable mounting angle. Due to the quality and geometric eccentricity of the motor manufacturing error
