Qualitative Dynamic Analysis of Mutual Interaction of Imperfections and Friction in Joints
Original language description
The presented work deals with the research of possible mechatronic systems and devices whose motion and performance depend on the introduced friction (generally passive effects) on one side and joint clearances, allowing more free motion on the other side. These two essential characteristics act opposite to each other, and therefore deep knowledge of their mutual interaction and effects on the positioning and dynamic behaviour of investigated systems is important in design. The well-known mathematical model based on the Lagrange equations, which can be expressed as a set of differential-algebraic equations, is briefly summarized. The imperfect joints are modelled by means of nonlinear forces, including various friction effects. The applications were limited to rigid body systems with rotational, translational and spherical joints (both ideal and real with clearances) and passive effects. The equations of motion of these systems were solved using numerical integration. A certain range of operating conditions was considered in all analyses and chosen kinematical quantities were evaluated in order to explore the mutual interaction of joint clearances and friction effects on system dynamics.
