Abstract:
The torque strut is a key mount in three-point pendulum mounting system of
powertrain. Its equivalent stiffness in two orthogonal directions is close to
zero meanwhile the equivalent stiffness in another direction always remains the
same as the original stiffness, which facilitates mounting system design and
matching and has been widely used. In this article, it is aimed to answer the
issues for the equivalence of torque strut mount theoretically, such as the
equivalent linear stiffness, equivalent torsional stiffness and equivalent
position. The torque strut mount has been simplified to an equivalent ordinary
mount, the equivalent linear stiffness and equivalent torsional stiffness are
derived, and has been verified by ADAMS, then the equivalent position is
discussed. The effect of the mass of torque strut on powertrain modals is
investigated. An equivalent model of powertrain mounting system with equivalent
stiffness at equivalent position for torque strut is established, the results of
the nature characteristics show that the equivalent torque strut model is usable
in engineering.
