Using multi-body dynamics technique, a full vehicle multi-body model for a SUV type is set up with ADAMS. A full vehicle handling stability is simulated and analyzed. A back suspension model which is able to describe its elastic deformation is established by the BEAM principle. According to three estimation methods of the open-loop model handling stability,(More)
An approach to polygonal approximation of regular digital curves based on PSO algorithm is presented. In this paper, each particle corresponds to a candidate solution to the polygonal approximation problem, which is represented as a binary vector. The offset error of centroid between the original curve and the approximation polygon, and the variance of(More)
Aiming at the problems of yarn and fabric simulation in woven fabric CAD system, the regular weaves and warp-backed weaves modeling is realized and the corresponding versatile algorithm is established. This modeling can automatically design the complex weaves with random ratio of warp and weft arrangement, and can automatically judge the covering-relation(More)
