  • SIMULATION OF TRACTION WORK TO RATIONALISE THE WEIGHT DISTRIBUTION OF THE 4WD ELECTRIC TRACTOR

    International Journal of Mechatronics and Applied Mechanics, 2024
    - Electric tractors, as the latest direction in agricultural machinery, have recently attracted considerable attention due to their environmental, economic and technological advantages. With the global transition to renewable energy sources and the tightening of requirements to reduce greenhouse gas emissions, electric tractors are a promising option for improving the agricultural sector. The aim of this type of material is to increase the overall efficiency of the four-wheel drive mini-electric tractor through the rational selection of the weight that falls on the tractor axle and the amount of internal pressure in agricultural tires. The objective was achieved by using a simulation model of the operation of a permanent magnet synchronous machine in Matlab and by incorporating the most loaded test cycles of DLG-PowerMix. The practical significance of the presented work consists in determining the change in the range of values of the weight distribution on the axle of the 4WD electric tractor and the pressure in the tires during aggregation on the most heavily loaded agricultural works, which will be useful when performing plowing and cultivation works on farmland. The scientific novelty of the work is the establishment of a relationship between the weight distribution on the axle of a 4WD electric tractor and the pressure in the front and rear tires of the driving wheels when simulating traction work according to the DLG PowerMix cycles of plowing and cultivation.
  • Mechanical and Surface Characteristics of Selective Laser Melting-Manufactured Dental Prostheses in Different Processing Stages

    Due to the expansion of the use of powder bed fusion metal additive technologies in the medical field, especially for the realization of dental prostheses, in this paper, the authors propose a comparative experimental study of the mechanical characteristics and the state of their microscale surfaces. The comparison was made from material considerations starting from two dental alloys commonly used to realize dental prostheses: Ni-Cr and Co-Cr, but also technologies for obtaining selective laser melting (SLM) and conventional casting. In addition, to compare the performances with the classical casting technology, for the dental prostheses obtained through SLM, the post-processing stage in which they are in a preliminary finishing and polished state was considered. Therefore, for the determination of important mechanical characteristics and the comparative study of dental prostheses, the indentation test was used, after which the hardness, penetration depths (maximum, permanent, and contact depth), contact stiffness, and contact surface were established, and for the determination of the microtopography of the surfaces, atomic force microscopy (AFM) was used, obtaining the local areal roughness parameters at the miniaturized scale—surface average roughness, root-mean-square roughness (RMS), and peak-to-peak values. Following the research carried out, several interesting conclusions were drawn, and the superiority of the SLM technology over the classic casting method for the production of dental prostheses in terms of some mechanical properties was highlighted. At the same time, the degree of finishing of dental prostheses made by SLM has a significant impact on the mechanical characteristics and especially the local roughness parameters on a miniaturized scale, and if we consider the same degree of finishing, no major differences are observed in the roughness parameters of the surfaces of the prostheses produced by different technologies.
  • HYSTERETIC DAMPING CHARACTERISTICS OF ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE USED IN HIP ARTHROPLASTIES
    International Journal of Mechatronics and Applied Mechanics, 2023
    This paper presents a theoretical model and experimental results to determine the hysteretic damping coefficient and the energy losses from the indentation process.The characterization of the ultra-high molecular weight polyethylene in terms of hysteretic damping has an important role in the evaluation of the reliability of the hip arthroplasties subject to vibrations and movement.This is done experimentally with the indentation technique.Following the indentation tests, it is observed that for this material creep is present during the unloading stage.In this study two types of ultra-high molecular weight polyethylene (UHMWPE): nonirradiated (conventional) CPE and gamma-irradiated (cross-linked) XPE were analysed.The hysteretic damping coefficient help in the evaluation of energy losses for the visco-elasto-plastic deformations of the material.The hysteretic damping coefficient can be considered an essential material parameter in assessing the state of stress and deformation of the material.This study shows the comparison between the two materials and the effect that irradiation has on its damping properties.

  • MASTER ERROR ELIMINATION IN FORCED GEAR ENGAGEMENT TESTING MACHINE USING HARMONIC ANALYSIS THROUGH FAST FOURIER TRANSFORM
    Dănuț-Iulian Stanciu, Gheorghe Gheorghe, Daniela Cioboată
    International Journal of Mechatronics and Applied Mechanics, 2021
    The growth in the capacity of production of gears and the higher industrial gear quality requirements call for the use of fast and accurate methods of checking gears right in the manufacturing flows. This paper presents a method of rapid and accurate verification of gears by applying the Fourier Transform analysis method to the variation of the distance between the shafts of two gears meshed together in a forced engagement. The paper also presents a method of replacing standard gears -used on test units featuring a tooth fitted between the standard gear and the measuring gear -with a regular gear, while maintaining the same level of accuracy of the measurement.

    Currently, intelligent robotic systems have become essential for industries. This paper presents two integrated quality inspection cells designed to be used in the manufacturing industry. The proposed systems combine several measurement technologies, robotic systems, and feeding systems, in order to provide an efficient solution for complex measurements tasks: an image processing system, contact measurement systems, a thread measurement system, non-destructive testing (NDT) principles -all integrated in flexible inspection cells. Additionally, the paper presents the design methodology of the two flexible inspection cells.

  • Optimization of pulsed laser based metal cleaning process

    International Journal of Mechatronics and Applied Mechanics, 2021
    The cleaning of metallic surfaces offers the possibility to reuse old components or to prepare components for processes such as painting, thermal treatment, etc. There are three main methods to clean metallic surfaces: chemical, mechanical and by using laser beam. The chemical method is expensive, time consuming and polluting, the mechanical one has similar disadvantages, hence laser cleaning is the most efficient of them and it is increasingly more used in industrial applications. In our work we use a 100 W fiber laser based device that includes the laser itself, an expander, a scanner and a variable focus device. The influence of the laser parameters (power, pulse repetition rate, fluence) on the quality of the surface (conductivity and adherence) has been studied and optimized. A possibility to decrease the required laser power in specific cases is envisaged. Cleaning of 3D surfaces is considered.
