Instant Centre Impact Loads Transfer on Double Wishbone Suspension While Car Traveling Straight

This paper focus on studying how the instant centre impacts loads transfer in double wishbone suspension model when vehicle moving straight (brakes or accelerates), instant center could further affects loads transfer by affecting inverse geometry values, worldwide specialists defined different ways to prove that instant centre has massive influences on the anti-geometry values. This paper by creating the double wishbone suspension Adams model and relatively auxiliary model to verify those theories and compare the results to find out the most accurate way to calculate anti-geometry value. Furthermore, this paper also proves the change of anti-geometry will affect tyre vertical and longitudinal loads transfer to resist the dive and squat of vehicle body when car brakes or accelerates.
