Abstract
Abstract. The dynamic characteristics of balance shaft module is
controlled by the design of rotating parts as how to allocate both a
unbalance mass and a supporting bearing so that the concept design of a rotor
structure is the key issue on determining the overall quality of dynamic
performance as well as fatigue resistance. Even the design on balance shaft
has some limitation from the lay-out of a vehicle engine system, there is
still chance to enhance the reliability of the balance shaft module by the
promising design model of the rotor structure including support bearing
locations. In this paper, an optimal location of unbalance mass and
supporting bearing is proposed to make an efficient conceptual design using
an objective function to minimize a bending deformation of rotor as well as a
reaction force at supporting bearing. In addition, the application of design
optimization of a balance shaft model is explained using an in-house program
for inline 3-cylinder and inline 4-cylinder engine, respectively.
