optimization of steering linkage including the effect of McPherson strut front suspension
International Conference on Swarm Intelligence, 2018Co-Authors: Suwin Sleesongsom, Sujin BureeratAbstract:This paper proposes to optimise the steering linkage including an effect of McPherson strut front suspension. Usually, the suspension is exerted with an impact force due to uneven road, which dynamically changes to performance of a steering linkage. The present work proposes to study an effect of suspension to performance of steering mechanism with comparative study of steering mechanism with and without suspension system, which is included in optimization problem. The performance is minimised in both turning radius and steering error, that is called multi-objective optimisation problems. The model of McPherson strut front suspension is simplified model but it is sufficient accuracy. The results show that the suspension is an important effect on the optimisation design and the optimisation results show that the design concept leads to effective design of rack and pinion steering linkages satisfying both steering error and turning radius criteria.

Optimization on lower control arm of McPherson suspension based on OptiStruct
Computer-Aided Engineering, 2012Co-Authors: Li ChengAbstract:As to the optimization of lower control arm of McPherson suspension including mass lightening and stiffness improvement,based on topology optimization theory and finite element method,topology optimization is performed on the lower control arm of a casting McPherson suspension by OptiStruct.The optimal material distribution in the required volume is achieved with maximum stiffness.CAD model is rebuilt after optimization,and then the stiffness and modal are compared with those of the original arm.The results show that the optimization can lighten the mass and enhance the stiffness of lower control arm.

Spatial autocorrelation in country-level models of species imperilment
Ecological Economics, 2007Co-Authors: Ram Pandit, David N. LabandAbstract:Abstract Modeling the determinants of species' ecological fragility using country-specific data may be complicated by the fact that factors that influence species imperilment may extend or operate beyond arbitrary political boundaries. Following McPherson and Nieswiadomy [McPherson, M.A. and Nieswiadomy, M.L., 2005. Environmental Kuznets curve: threatened species and spatial effects. Ecol. Econ. 55: 395–407.], we confirm the advisability of controlling for spatial autocorrelation in models focusing on imperilment of birds, mammals, reptiles, amphibians, and vascular plants. We also compare the performance of different definitions of the spatial dependency. Although our a priori expectation was that measures that more accurately reflect the degree of spatial interaction between countries, such as the percentage of shared border, would be superior to a measure of simple adjacency, in fact we find that the simple adjacency measure outperforms the other measures in most cases.

Introduction to the McPherson number, $\Upsilon(G)$ of a simple connected graph
arXiv: Combinatorics, 2014Co-Authors: Johan Kok, Susanth CAbstract:The concept of the \emph{McPherson number} of a simple connected graph $G$ on $n$ vertices denoted by $\Upsilon(G)$, is introduced. The recursive concept, called the \emph{McPherson recursion}, is a series of \emph{vertex explosions} such that on the first interation a vertex $v \in V(G)$ explodes to arc (directed edges) to all vertices $u \in V(G)$ for which the edge $vu \notin E(G)$, to obtain the mixed graph $G'_1.$ Now $G'_1$ is considered on the second iteration and a vertex $w \in V(G'_1) = V(G)$ may explode to arc to all vertices $z \in V(G'_1)$ if edge $wz \notin E(G)$ and arc $(w, z)$ or $(z, w) \notin E(G'_1).$ The \emph{McPherson number} of a simple connected graph $G$ is the minimum number of iterative vertex explosions say $\ell,$ to obtain the mixed graph $G'_\ell$ such that the underlying graph of $G'_\ell$ denoted $G^*_\ell$ has $G^*_\ell \simeq K_n.$ We determine the \emph{McPherson number} for paths, cycles and $n$-partite graphs. We also determine the \emph{McPherson number} of the finite Jaco Graph $J_n(1), n \in \Bbb N.$ It is hoped that this paper will encourage further exploratory research.
