“…Such an algorithm has exhibited good applicability to even more tough problems solved by Tian et al [25][26][27][28] and by Liu et al [29] to study the dynamics of a flexible multibody system with clearance joints. Readers can also gain an insight into the efficient parallel computation strategy in the work by Liu et al [29].…”

“…The arc-length method [20,21] is used to accurately trace the nonlinear equilibrium path, and the bifurcation analysis without introducing any imperfections into structures is performed via the approach of mode injection [22]. Then, for the dynamic simulations of thin shell systems, the generalized-alpha algorithm, which has been studied in many studies [23][24][25][26][27][28][29], is employed to solve the dynamic equations.

A new hyper-elastic thin shell finite element of absolute nodal coordinate formulation (ANCF) is proposed based on the Kirchhoff-Love theory. Under the condition of plane stress, a two-dimensional compressible neo-Hookean constitutive model and a twodimensional incompressible Mooney-Rivlin constitutive model for the thin shell element of ANCF are derived. Based on the continuum mechanics, the efficient analytical formulations of the internal forces and their Jacobians of the shell element are also deduced. Then, a computation methodology for performing the nonlinear static analysis including buckling analysis of hyper-elastic thin shells is proposed. To accurately track the load-displacement equilibrium path in the analysis, the arc-length method is used to solve the nonlinear algebraic equations. The dynamics of the thin shells made of different hyper-elastic materials is also comparatively studied by using the generalized-alpha algorithm. Finally, six case studies are given to validate the proposed hyper-elastic thin shell element and computation methodology. The influence of different constitutive models on the static and dynamic responses of thin shells is revealed.

“…For soft materials, Flores et al [20] proposed a continuous contact force model in multibody dynamics. Lubricated revolute joints [21,22] were also carried out on the dynamic response of multibody systems. An efficient computational method was investigated to deal with contact detection in multibody dynamics [23], and an approach to stabilizing the constraint violations in dynamic simulation was studied [24].…”

A new computational methodology is presented for the dynamic analysis of multibody systems with multiple clearance joints by vector form intrinsic finite element method. A joint model is developed to simulate the motion of ideal and clearance joints for multibody systems. The dynamic behaviour of a four-bar mechanism with three clearance joints in continuous contact mode is analysed. The results show that the dynamic performance of the mechanism with three clearance joints in continuous contact mode is not similar to that with ideal joints and is fluctuating and affected by the clearance size of the joints and input crank speed.

Abstract. The purpose of this paper is to derive the simplified elastohydrodynamic (EHD) lubrication model of the double involute gear (DIG) and study the effect of the segmented tooth waist on the lubricating properties of DIG. Geometric analysis of the DIG gear was performed on the simplified EHD lubrication model based on the engagement theory, and then the line contact steady isothermal Reynolds' equation was established. Numerical analysis of EHD lubrication of the new gear drive was conducted by using the multi-grid method.
