  • Patent number: 5744724
    Abstract: A shaker table (10) for testing and quality control of devices attached to the table is shown. The mounting table has pneumatic exciters attached (50) thereto. The exciters (50) are attached to the mounting table (20) with a mounting bolt (128) and spacers (132, 132') that comprise an insulating material to inhibit thermal transfer between the device and the exciters (50) and between the mounting table (20) and the exciters (50). The mounting table (20) provides uniform distribution of forces applied by the pneumatic exciters (50). The forces are evenly distributed in all directions from the impact of the exciters on the mounting table. The mounting table (20) is supported on a foundation (2) by adjustable supports (4). The exciters are supplied with pressurized air from a source (12) through an airline (14).
