Unformatted text preview: 2009-05-0611Review Questions 5Review Questions 51.If two different dynamic systems have the same transfer function for input force and output response, is it true that their dynamic responses in operating conditions at the same frequency are same?conditions at the same frequency are same?2.In usual machineries, what is the highest velocity that can be classified as ‘good’ in vibration severity? How about the highest velocity magnitudes for ‘satisfactory, unsatisfactory, impermissible’ classes in vibration severity? Refer to Fig. 5.1.3.Is it better to use a soft spring in the isolator of a machine? If so, why?4.How does the force transmitted to the base change as the speed of the machine increases?2Review Questions 5Review Questions 55.What is the force TR for a force excitation from a isolated machine to the fixed base? What is the force TR for a motion excitation from the moving base to the isolated machine? What is the motion (displacement)isolated machine? What is the motion (displacement) isolated machine?...
