1/15/2024 0 Comments Vibration springStudents may try their own fluids (provided they are safe and do not damage the equipment) and their own piston discs for project work. For example: water and vegetable oil will produce light damping, while castor oil produces heavy damping. It works with easily found non-toxic fluids (not supplied) for different damping levels. This simple piston disc and cylinder form a dash-pot damper that fits to the guide rods under the platform. Students may fit an optional Damper Kit (TM164a) to test how viscous damping affects the system oscillations. However, the sensor outputs may be connected to your own data acquisition system or oscilloscope if desired. TecQuipment have specifically designed the TM164 to work with VDAS® (mkII). Students can then see and compare both the measured and derived acceleration at the same time, to confirm the relationship. The software calculates and shows the first two derivatives of displacement - velocity and acceleration. Students use the software to see both the displacement and acceleration wave-forms to confirm the phase difference between them and measure frequency. TecQuipment calibrate the sensors to work with VDAS® (mkII) for real-time display and data acquisition of system oscillation wave-forms. They then find the frequency of oscillation and compare it with that predicted from theory. Students pull the platform gently down and release, allowing it to vibrate. Students use it with a cursor on the platform to measure accurately the spring extension, to show Hooke’s Law and find the spring constant. Both sensors measure the motion, yet create negligible damping. An additional sensor (accelerometer) built into the platform measures the acceleration of the platform as it moves up and down. The displacement sensor measures the vertical oscillations of the platform. Students fit additional masses to the platform, and a second spring is provided to test various system combinations. A test spring suspends a balanced mass platform which vibrates (oscillates) vertically in the guide rods. The panel holds two vertical guide rods and a non-contacting displacement sensor. Therefore, students can easily make the link to simple harmonic motion - defined as the oscillatory motion where the restoring force is proportional to the displacement. This is because students may already be familiar with Hooke’s Law, showing the force exerted by a spring is proportional to the extension. The mass-spring system is one of the most easily explainable oscillatory systems. This product fits to the sturdy Test Frame (TM160) for study or demonstration.
