本文介绍了落砂机实验台的研制过程、试验台的结构特点、工作原理和技术规格等。同时,还介绍了该实验台可供从事的实验项目和测试数据,如自振频率、强振园频率、频率比、偏心块同步状况、激振力、振幅、抛掷指数、落砂指数、电机功率及噪音等。实验所取得的数据,对研制、设计先进高效大型生产用落砂机有着一定的指导作用。

This paper introduces the development process of the bench for the falling sand machine, the structural characteristics, working principle and technical specifications of the test bench. At the same time, it also introduces the experimental items and test data that the experiment bench can be used in, such as the natural frequency, the vibration frequency, the frequency ratio, the synchronization condition of the eccentric block, the exciting force, the amplitude, the throwing index, the falling sand index, Power and noise. The experimental data obtained for the development, design and efficient production of large-scale production with a sand machine has a guiding role.
