Applications IV: Simulation
Many of the engineering systems which suffer from random vibration are of considerable complexity, so that fully instrumented testing in service is just not practicable. Also sub-components of such complex systems are often separately supplied, so that there is a need to demonstrate their capacity for survival by tests which take place outside the parent equipment. Such considerations have led to an interest in simulating in the laboratory vibration conditions which occur in service. It is therefore important to consider how vibration conditions can be simulated, and to consider in particular how this can be done economically, using relatively simple testing equipment.
