Vibration Velocity

Velocity refers to the rate of change in the position of a product. Speed varies during vibration testing. At the highest point, or peak, of the cycle, the product is momentarily at a standstill and the velocity is zero. Then, the product descends and picks up speed. The product reaches the point of greatest negative velocity when it crosses the rest position; after which point, the product begins to slow down. At the lowest point, or trough, of the cycle, the product is again momentarily at a standstill and the velocity is zero. It begins the process again by climbing up and gaining positive speed.

Hence, Vibration Velocity means the changing rate of displacement (D) to time. Unit:mm/s, cm/s
