Analysis Methods and Results of Digital Dynamic Analysis of the Minuteman Transporter-Erector 630375
Vehicle suspension systems are normally analyzed under the assumptions that structural flexibility is unimportant and suspension system components display linear characteristics. These assumptions may be justifiable in most instances but will sometimes give completely erroneous results. The responses of the Minuteman Transporter-Erector to an artificially roughened test course have been calculated, using structural flexibility and suspension system nonlinearities. The nonlinear flexible analysis maximum responses agreed with test results within the test scatter band. The results show that the nonlinearities and flexibilities of the system are required in the analyses in order to determine realistic responses.
