Horizontal shaking is accomplished through use of 4 TEAM Corporation Horizontal Actuators. The horizontal actuators are used during Vertical testing to counteract cross axis forces and overturning moments.

The SPF Facility layout is ideal for performing multiple test programs. The facility has two large high bay areas adjacent to either side of the vacuum chamber. The advantage of having both areas available is that it allows for two complex tests to be prepared simultaneously. One test can be prepared
