Automotive suspensions are discussed in Chapter 4
in connection with the vertical motion and ride properties of vehicles. A two-DOF quarter-car model was used, which is simple
but sufficiently detailed to capture many of the key suspension-performance tradeoffs, such as ride quality (represented by sprung-mass acceleration); handling (represented by tire deflection); and packaging (represented by suspension
stroke, also known as the rattle space). The performance index (see Chapter 4
, Example 4.9) combines these three performance measures by assigning adjustable weights to the three performance terms.
Studies show that passive suspensions frequently are tuned to achieve good tradeoffs. Any improvement in one aspect of ...
