“…Jiaohua Zhang [5] et al designed a non-contact measurement system for the lateral vibration of escalator chain drive based on image processing technology to verify the reliability of the overall operation of the chain drive system. Baofu Kou [6] et al conducted lateral vibration simulation and experiments on a chain drive lifting system by adjusting the compacting mechanism parameters, effectively suppressing lateral amplitude. Chen [7] used Ansys to analyze the vibration characteristics of the Hy-Vo tooth chain system with an internal-external composite meshing mechanism and simulate the vibration phenomena of multi-sprocket transmission system.…”

The waste power battery drive system utilizes a unique form of chain drive that connects the silo. However, due to the large vibration amplitude of the silo during actual operation, it was necessary to establish a three-dimensional model of the automatic feeding mechanism using Solidworks. Through Solidworks/simulation modal analysis, the relationship between the excitation frequency and the natural frequency of the system was analyzed and compared. Furthermore, the model structure was imported into ADAMS for dynamic simulation analysis to study the impact of chain speed, load, and silo number on the system's operational stability. The simulation results indicate that, for this type of low-speed chain drive mechanism, the silo generates periodic excitation to the system through the sprocket. It is important to keep this excitation away from the first-order natural frequency of the system. Moreover, the load quality within the design scope has little impact on the system, and increasing the number of silos can help to enhance the stability of the system's operation. The above conclusions are important for suppressing vibrations in such forms of chain drives.

The non-destructive tests (NDT) of the steel wire ropes put on the crane pulley blocks comprise more than a half of our NDT services. The intensive utilization of cranes often leads to critical situations endangering health and safety at work. The operators are forced to provide safety use of the cranes due to new cranes constructions, new construction of the block pulley and put on the new steel wire rope constructions. The NDT tests of the crane steel wire ropes are coordinate by the Standard ISO 4309. We have experienced only the crane steel wire ropes with an individual wire rope core during our NDT tests so far. The visual NDT test usually used is ineffective to the steel wire ropes with this construction. Based on our previous experience it can be confirmed that surface ruptures are produced after the disintegration of wires inside of a rope; it often leads to the rope abruption during its operation. The reduction of the pulley block dimensions often leads to the problem of the multi-axis rope bending. This kind of the rope line in the pulley block causes the increase of the fretting fatigue of the wires and the rope strands. The same type of the stress is created when the dead ends of the rope are badly constructed.

In our laboratory we quite often experience problems with the operation of steel ropes. There is a range of causes related to lifetime problems of ropes. These problems are related to poor quality of input material used for wire production, mixing of different wire strengths in the rope construction, improper roping of the rope into the hoist system, improper rope operation, improper rope design for a particular type of operation as well as unfair practices of vendors. The subject of the article is the analysis of the rope showing the combination of a large number of the above factors leading to the damage of the rope. During the operation of the cargo cableway, the hauling ropes were damaged in a very short time. The Z wires from the surface layer of the rope started to release from the rope. Subsequently, the wires were unwinding from the layer, they created visible protuberant waves, they were braking and dropping out from the rope. The hauling rope had to be replaced. Than the samples were taken from the rope in order to find out the cause of the rope damage. Mechanical, metallographic and fractographic measurements were performed on the rope. The metallographic and fractographic measurements revealed the material defects of the wires of the rope caused during manufacturing of the Z wires from the surface layer of the hauling rope. The mechanical tests revealed differences in the tensile strength grade the operator required compering to the tensile strength grade the vendor declared. The above mentioned problems unambiguously show that it is appropriate to introduce a mechanical control of the rope properties in advance to its deployment. Checks must be performed by an independent testing laboratory. This procedure overprices inputs needed for the rope replacement. On the other hand, it can reduce the costs when a poor quality rope is deployed. Some of our customers have already adopted this approach. It helped to the increase in the safety of the operation of the mechanisms and it eliminated the problems with exchange and climes on bad quality ropes.
