“…Grinschgl et al 25 found the impact velocity and forces at the bearing of the sprocket by creating a three-dimensional finite element model. The chain bed is considered as a rigid body, while the rest of the sprocket is modeled as a deformable body.…”

The unique properties along with ease of manufacturing make short fiber reinforced polyamide 66 composites ideal for sprockets used in low positive power transmission. An explicit dynamic finite element simulation of short fiber reinforced polyamide 66 composite sprocket—roller chain drive was carried out. The sprocket was approximated as a plane stress body and roller was considered as a rigid circle. The contact force extracted from the numerical simulation was validated with the analytical results for a standard chain. The deviations in the pitch of the chain produced a varied dynamic contact behavior in terms of a distinct contact width and pressure distribution pattern. The position of maximum contact shear stress altered from subsurface to surface due to low contact normal stress and associated slip. The variation in the chain pitch (up to 3%) affected the peak force of driver sprocket significantly (up to 41%). The increase of pretension of roller chain from 100 to 300 N induced the rise in contact force of driver sprocket up to 169% without changing the pattern.

“…10,11 The effect of the polygonal action is to produce a periodic variation in the velocity ratio and a large dynamic load in the chain, 12 thus reducing the chain’s fatigue life and causing noise. 13,14 This undesirable effect motivates researchers to investigate the dynamic behaviour of chain drives.…”

Round link chain drives can be sorted into the transmission, parallel conveyor and non-parallel conveyor systems according to their applications and guide rail’s layouts. The polygonal action in these systems is irregular. Compared with the literature, this paper proposes a more accurate modelling approach to capture the dynamic behaviour of round link chain drives, which can consider both the irregular polygonal action and non-parallel guide rail’s layout. The dynamic models of the three types of round link chain drives are developed based on the finite segment method. The chain is divided into multiple discrete segments that are connected by Kelvin models. To account for the irregular polygonal action, the sprocket is equivalent to an irregular polygon. To consider the non-parallel guide rail’s layout in the conveyor system, the chain segment out of the guide rail and the corresponding sprocket are treated as a swinging-block mechanism. The proposed approach is applied to model a scraper conveyor. Simulation results show that the irregular polygonal action and non-parallel guide rail’s layout greatly increase the fluctuation of the chain tension force.

“…The simulation results showed that the composite sliding mode controller of the permanent magnet direct drive system can realize the smooth start of scraper conveyor. Grinschgl et al [18] proposed a chain drive modeling strategy combined with multibody simulation and finite element method. They also compared the simulation and experiment of a simple doublechain drive.…”

The scraper conveyor is the unique transport equipment in coal mining face. Its chain drive system is the core subsystem. The dynamic characteristics of the chain drive system need monitoring for a safe mining. Existing monitoring methods include controlling the chain tension, chain speed and motor current. However, the above-mentioned methods have many disadvantages, such as difficult and costly to implement in mining face, due to the poor working environment and the limitations of the scraper conveyor's structure. This study proposes a monitoring method for the dynamic characteristics of the scraper conveyor on the basis of the speed difference between the head and the tail sprockets. Such an initiative is carried out to study the dynamic characteristics of the scraper conveyor under real working conditions and describe its running state. The speed difference of the head and tail sprockets under different chain speeds, terrains, and loads is monitored and studied. Research results show that the average and maximum speed differences are 0.797% and 0.990%, respectively. Due to the complex terrain, the tighter the scraper chain gets, the smaller the difference of the rotational speed is, compared with the flat working condition. The speed difference under load greatly increases compared with no load. Research results provide data support for the research of the chain drive system dynamics of the scraper conveyor. These results will also provide a new idea for the monitoring of the operating state of the scraper conveyor.
