| RVM-I Rotary Shaker Machine |
| The GHI Systems Rotary Vibration Machine (RVM-1) is intended to provide sine and random rotational vibration to a product. The mechanical system is comprised of an electrodynamic actuator, rotational table and stinger interface. The system includes a computer based system for control of vibration input channels which can be configured individually, the average of the two channels or the extremal, which is the highest of the two. The primary test which this machine is designed for is transportation simulation and its effects on hard disk drive bearings. The drive is mounted on the rotational table such that the platters hub is centered on the table. The table is driven with a predetermined spectrum that simulates the transportation environment |
