Effects of wear on dynamic characteristics and stability of linear guides

Wang Wei, Zhang Yimin, Li Changyou, Wang Hao, more

Meccanica > 2017 > 52 > 11-12 > 2899-2913

Wear between elements significantly affects the dynamics of a linear guide. Several existing contact stiffness models were used to investigate the dynamic behaviors of linear guide systems. However, the wear of linear guides has been rarely investigated due to difficult prediction of contact load and wear mechanism. To solve this problem, an improved wear prediction method was developed in this study...

Acta Mathematica Scientia > 2012 > 32 > 3 > 1213-1225

In this article, we focus on the eigenvalue problem of the following linear biharmonic equation in ℝ ^N △ 2 u − α u + λ g ( x ) u = 0 with u ∈ H 2 ( ℝ N ) , u ≠ 0 , N ≥ 5. Note that there are two parameters α and λ in it, which is different from the usual eigenvalue problems. Here, we consider λ as an eigenvalue and seek for a suitable range of parameter α, which ensures that...

Theorem Proving Based on the Extension Rule

Lin Hai, Sun Jigui, Zhang Yimin

Journal of Automated Reasoning > 2003 > 31 > 1 > 11-21

Methods based on resolution have been widely used for theorem proving since it was proposed. This paper presents a new method for theorem proving that uses the inverse of resolution and employs the inclusion-exclusion principle to circumvent the problem of space complexity. We prove its soundness and completeness. The concept of complementary factor is introduced to estimate its complexity. We also...

An analysis of import protection as export promotion under economies of scale

Zhang Anming, Zhang Yimin

Japan & The World Economy > 1998 > 10 > 2 > 199-219

This paper examines Krugman's (1984a) argument that under increasing returns to scale import protection may act as a form of export promotion. We formally prove Krugman's result by explicitly using stability conditions for a multimarket Nash equilibrium. We also develop the welfare economics of the export promotion argument. Here protection allows profits to be shifted to the domestic firms, not...

Transportation Research Part B > 1996 > 30 > 1 > 11-18

This paper deals with the socially optimal pricing of airports in a hub-and-spoke network, taking into account explicitly the fact that demands for airport services at hub airport and spoke airports are complementary. It is shown that a welfare gain is to be made by switching from the regime of pricing each airport independently of other airports in the network to the regime of pricing the hub and...
