Remarks: contact forces First approach the “equivalent air spring” is the best approach for wheel rail contact force calculating – Few configuration parameters are required, very low calculating time, output results agree with the other, more complex, models – Good design methodology – Good the comparison with the running tests 21st and 22nd March 2006 SIMPACK User Meeting 2006
Remarks: comfort The “equivalent” air spring gives good efforts for its simplicity, but calculation output doesn’t depend on frequency of the input Unsuitable for comfort analysis, the second modelling approach is needed to simulate the load transfer into the vehicle car body The linear spring gives a more realistic description of vehicle comfort – More parameters are required – More CPU time is spent – More modelling time needed – Good solution for comfort analysis adopting the flexible body model 21st and 22nd March 2006 SIMPACK User Meeting 2006
