Design and Construction of a Vibration Isolator Inspired By a Kangoroo
Reference: VIBISOL2 (Acronym)
Student: Sabahattin Bora Günay
There are various approaches to isolate a system/instrument/building from vibration. Such systems are available for isolating buildings from earthquake effects, electronic instruments from the body of aircraft/spacecraft, cameras from the body of moving journalists / cameramen, etc. Some of these isolators are for large bodies and do not have significant size restrictions that may hinder their functioning. The project involves feasibility investigation, design and construction of an isolator inspired by a jumping kangoroo*, which has to fit in a tight volume. Referring to the above figure, which shows a schematic of such an isolator, when a time-varying force f is applied to the mas sor to the base, a small portion of it should be transmitted to the opposite end. The task is to find optimum parameter values so that minimum force transmission is achieved.
- Literature survey
- Understanding the standart that will be used in the design.
- Derivation of the equation of motion of the system in the figure.
- Solution of the nonlinear equation of motion and optimization of the parameters.
- Construction of the isolator and experimentation.
Required Qualifications and Skills:
- To be enrolled in or to have taken ME 445.
- Interest in theoretical and experimental work.
