Abstract
Recently, for weight and cost reduction the new mount and
sub-frame system has been ongoing research. As a result, through
the application of H-type sub-frame, a pendulum-type engine
mounting system with engine, transmission, and roll mount have been
proposed. However, the freedom of the design has been largely
limited to obtain the optimal performance between the control of
powertrain behavior and the vibration isolation influencing the
durability of the mount and NVH quality simultaneously.
So, 4 different type of roll rod was taken into account and
validated experimentally in this study under the maintenance of
same platform, the contribution of load sharing and NVH performance
was to optimize. It is shown that CTR roll rod is more effective
than any other type to compromise the efficiency between durability
and NVH. In conclusion, from an experimental review related with
booming noise, interior noise and excessive vibration the sharing
load of roll mount was reduced by 35% in 1WOT. Also, AI performance
3% in more than 2200 rpm band, C2 interior noise 3 ~ 5 dBA in the
band 2700 ~ 3700 rpm and excessive vibration during startup 0.5
m/s2 (seat anteroposterior direction) improvement is obtained. In
addition, to satisfy the required performance the dynamic stiffness
of H-type sub-frame is presented.
