The automotive suspension testing stand of virtual automobile body clamp suspension testing stand and Publication No. CN103954459A.But for half active/master
The suspension frame structure of 1/4 automotive suspension testing stand of dynamic suspension has made excessive simplification, such as Publication No. relative to real vehicle
Automobile a quarter simulation electromagnetic suspension, mechanical vibration exciter and its testing stand of CN104897420A does not account for irs control arm
With the influence of the suspension frame structures part such as steering linkage, and the testing stand can not carry out the experiment of real suspension system, without logical
The property used.And most Active suspension experiment needs to complete by expensive dSPACE equipment.In addition, 1/4 current automobile
Suspension testing stand does not have the ability for carrying out damper and spring performance experiment.
