HSV-2000 High Speed Vibrometer - Applications

The HSV is designed to investigate high speed processes such as:

• High speed machinery kinematics
• High speed  engine valve dynamics
• Ultrasonic welding
• Explosion, shock impact, door slam and other transient high speed events

Combustion Engine Development

The gas exchange cycle is extremely important for combustion engine development because of its influence on the mixture formation and combustion processes. Valve train performance (kinematics and dynamics) is intimately associated with this cycle and offers considerable opportunity for increasing engine performance. The HSV-2002 is a unique tool that significantly contributes to advanced valve train engineering by allowing for independent measurements of both valve lift and velocity. Displacement and velocity up to 160 mm and 30 m/s, respectively, may be measured. This is important for detecting high frequency bouncing effects. Both results and resolution are independent of distance, material properties and temperature. The sensor is installed in a safe distance avoiding  temperature and oil pollution problems. Using the HSV 2002, development engineers can now optimize valve train parameters early in the product development cycle.

Fatigue Testing of Turbine Blades

If continuous amplitude and resonance frequency monitoring of test structures (e.g. turbine blades) is required, the HSV  is the best choice. In fatigue testing setups, where structures are excited at their resonant frequencies, the HSV enables noncontact monitoring of high amplitude displacement from a safe standoff distance. Durability can be measured by the number of cycles necessary for the onset of cracking, allowing verification of numerical predictions.

High Speed Measurements Through a Microscope on Bubble Jet Drops

For bubble jet printers the ink drop velocities can be as high as 30 m/s. Only the HSV High Speed Vibrometer is  capable of making measurements at such high velocities. The HSV can be combined with a microscope via the CLV-A-Micro adapter piece. The measurements are made on the bubble jet drops when leaving the printer head capillaries.
