Analytical Solution to Single Degree of Freedom Bi-Linear Spring Mass Systems Transient Vibration
Abstract: Conventional approach to solution of linear systems under transient vibration has been through Convolution integral or Duhamel integral method which employs the method of superposition of linear solutions to obtain the total solution. Principle of superposition is not possible for non-linear systems and hence transient vibration solution cannot be obtained through classical methods. Nevertheless, the solution to transient vibration for each domain can be obtained as a sum of homogeneous …
