Accordingly, the corresponding lateral force at the vehicle unit's CG will cause the sprung mass
rotates at an angle, which is mainly determined by the vehicle forward speed.
A vehicle model consist of a two degrees of freedom, the vehicle mass with passenger is represented by the sprung mass
(ms) and the mass of wheel and associated components are represented by an unsprung mass (mu).
These vehicles can also control the motion of the sprung mass
by driving force distribution using the suspension reaction force generated by IWM drive.
The MR dampers also function as a component of Integrated Dynamics System via two unique damper tuning settingsone biased toward unsprung mass control, used for Quiet and Sport modes; and a second with optimized performance tuning biased toward sprung mass
control, used for Sport+ and Track modes.
If the SWS is too small, the sprung mass
will strike the un-sprung mass
and this may lead to damage of the vehicle.
The reason is that the studied half- and full-car suspensions are always aimed at the conventional sprung mass
damper-based quarter-car suspension structure, even though the linearization technique is utilized for modeling the suspension dynamic system by reasonably ignoring nonlinearities of the damper and car components.
Nonlinear equations of the sprung mass
and unsprung mass motions can be derived in two parts as follows .
s], kg Sprung Mass
1800 L/W/H, mm Length/Width/Height 4550 * 1700 * 1660 [I.
The numerical values of the suspension model parameters for Kubota M110X tractor are proposed as follow; sprung mass
M1 = 700 kg, un-sprung mass
M2=90 kg, spring stiffness k1= 62000 N/m, k2 = 570000 N/m, damper constant b1= 500 N.
Using the present analysis, sprung mass
model can also be analyzed.
To test whether the cyclic compression of each segment resembled harmonic motion of a sprung mass
, the differences in Vx at each end of a segment were compared with changes in Lx (Fig.
Kotagiri adds the configuration is lighter than an independent rear suspension, weight neutral to a solid rear axle configuration, and reduces sprung mass
by upwards of 20%.
