A high load capacity non-pneumatic tire (HC tire) was designed and manufactured to solve the problems of air leakage, puncture, blowout, shoulder void, delamination, which occur in traditional tires, as well significantly increase unit tires. Experiments numerical simulations were conducted investigate static stiffness properties HC tire. Additionally, manufacturing process highlighted. The mainly comprised polyurethane silicon manganese steel, a ‘π’-shaped support substructure adopted....

Estimation of the tire-road friction using signal on-board sensors is very important for vehicle dynamic control systems. This paper presented a tire -- Croad coefficient estimation algorithm based on modified Dugoff model. The proposed first determined slip ratio and instantaneous longitudinal wheel dynamics parameters. Then, was estimated through model with subsection method converse solution method. effectiveness performance were demonstrated simulations different road surface conditions.

We report an experiment designed to test for the impact of giving more information feedback about others’ choices in previous period on coordination a repeated minimum-effort game. consider full and limit treatments. Our results indicate that group coor- dinates at higher level effort treatment reach equilibrium success than group. Compared studies, we can observe outcome long run by repeating game 50 times is subjects this historical last 10 periods

This paper is devoted to study the symmetry and monotonicity of positive solutions for linear coupling elliptic systems in a ball . Using Alexandrov–Serrin method moving planes combined with strong maximum principle, we prove that couplings are symmetric w.r.t. 0 radially decreasing. For our problems, tangential gradient conditions play important roles using plane method. Our results on further research based existence [1 Su JB, Tian RS, Zhao LG. Bifurcations couplings.
