【文章內(nèi)容簡(jiǎn)介】 ndicating functions of secondary suspension vehicles at the same time, then conducted the simulation on secondary suspension vehicle by applying the multipoint coordinated excitation modal chapter three, taking the secondary suspension model car as the object, taking the multipoint coordinated excitation theory as the basis and the Labview as the piling platform, a multiinput and multioutput pure modal test system was developed. The system made an optimization design on the adjustable force interval of force signal via grid method。 the feedback control of the system was achieved by using purity as the target last, with the developed modal test system, multipoint coordinated excitation modal test was conducted on the secondary suspension model car, and the natural frequency and vibration
