“…Wang et al [18] and [19] proposed an improved normal contact force model and modified Coulomb friction model and took the crank slider and four-bar linkage mechanism as research objects to analyse the impact of clearance on the dynamic characteristics of the mechanism. Matekar and Fulambarkar [20] established a crank slider simulation model without clearance or adjustable clearance by Adams, analysed the impact of clearance on the slider displacement, and verified the simulation results through experimental devices. Tajaril et al [21] established the mathematical model of the mechanical system by adding spherical clearance to a hexapod robot, obtained the impact of clearance on the position accuracy of the robot and verified the results through experiments.…”

Hydraulic support is a complex parallel mechanism composed of multiple kinematic pairs. In the work of hydraulic support, clearances between kinematic pairs are inevitable, which lead to the deterioration of the support’s working performance, and may even affect support’s normal work in serious cases. To study the influence of clearances on hydraulic support and simultaneously avoid the mutual interference between different clearances, the normal and tangential force models of kinematic pairs with clearance are established, based on the Lankarani-Nikravesh contact force model and the Coulomb friction model. Furthermore, the dynamic model of the hydraulic support with single clearance is established by adding a clearance between the rear link and base and, according to the dynamic model of the hydraulic support, the research about the influence of clearance on the movement and force of hydraulic support is carried out, which proves the need to study the clearance of hydraulic support. Moreover, the influence of clearance, clearance size, and different oil inlet drive modes of front and rear columns on the stability of hydraulic support are analysed, and then the change of hydraulic support posture caused by clearance and clearance size is considered. The results show that clearance causes the movement and force of the rear link to fluctuate, which affects the stability of the hydraulic support. The clearance size affects the fluctuation degree of the movement and force, which is an important factor in the instability of hydraulic support. Also, the hydraulic support posture is changed by the clearance and clearance size. Different column oil inlet drive modes have different impacts on the clearance and have different effects on the stability of hydraulic support.

“…Many researchers have executed the simulation and analysis of the slider-crank mechanism using ADAMS/View. A study was conducted to investigate the effect of slider displacement joint clearance on the mechanism (the slider-crank) [9]. In the study, ADAMS/View program was utilized to simulate and model the slider-crank mechanism.…”

Dynamic analysis is important in understanding the movement of a mechanism and the forces it transmits. In this study, an analysis was carried out for the change of the force transmitted by the slidercrank mechanism depending on the system parameters. The mechanism used in the study consists of crank, connecting rod, piston, and elastic element. Within the scope of the study, firstly, a model of the mechanism was created in the ADAMS/View environment. In this model, a force is applied to the mechanism through the crank limb. This applied force is transferred to the spring element in the model via motion transfer elements. The effect of the applied force was observed through simulations depending on the change of system parameters (stiffness and damping). In the simulations performed, it has been observed that as the spring stiffness changes, the mechanism moves oscillatory regardless of the force applied to the system, and as the damping increases, the mechanism moves more stable.
