摘要
在原线性振动烘干机的基础上,建立非线性空间双质体振动烘干机的运动方程,求解系统两振动电动机轴的平均振动阻矩、系统的同步性指数与稳定性指数等参数,经振动同步性试验,得到在振动阻尼条件下振动烘干机实现振动同步应满足的两振动电动机转差率应小于1.3%、非对称安装的相对误差小于0.3%等条件。将其用于烘干机工程现场,开发的新型振动烘干设备——ZHF3型双质体非线性振动烘干机,经生产用户试用,能大幅降低系统功耗与维修频次,明显提高系统稳定性和整机使用寿命,具有物料磨损小、破损率低,效率成倍提高,经济性好等特点,具有推广应用前景。
The movement equation of nonlinear space double-mass vibrator dryer based on the old linear vibrator dryer was established, a series parameters such as the average vibration resistance of the axises of the two motors, the index number of synchronism and stability and so on were gained. The synchronism of vibration of the space-moved mechanical system could be realized on the condition of vibration amortization which should need for the two-motor＇s rotating dislocation less than 1.3%, no-symmetric setting dislocation less than 0.3%. Applying it to the project scene, lead to a new equipment ZHF - 3 double-mass nonlinear vibrator dryer. Practical operation effect showed that dryer has the characteristics of low cost, low obstacles, high stabilization, high efficiency and good prospect.
