“…3 Belt conveyor scheme [23] Belt conveyors are usually similar in design and include the typical elements indicated in Fig. 1: drive drum (1), loading tray (2), pressure rollers (3), cleaning device (4), deflection drum (5), end drum (6), shock-absorbing roller support (7), lower roller supports (8), transport belt (9), upper roller supports (10). As per Bucklin et al, the following physical and mechanical properties of the conveyor are used for grain transportation: average bulk density is 0.6-0.8 t/m 3 , angle of natural inclination at rest -22°, in motion 19°, the abrasive group -A, with a slight degree of mobility, coefficient of external friction on rubber -0.4-0.5 t/m 3 , on steel -0.3-0.4 t/m 3 , internal friction coefficient -0.5-0.8 t/m 3 [24].…”

The purpose of the study is to examine the efficiency of transportation and productivity of the process of moving grain cargoes, with the improvement of the design and technological scheme of the belt conveyor when clogged with grain dust. Using the methods of analysis, synthesis, and comparison, the basic concepts and applied studies of belt conveyor performance by operating parameters are investigated to justify the optimal design and technological actions that reduce energy intensity and substantiate the economic efficiency of agricultural production. The results indicate that the study allowed determining the dynamic loads that lead to failures of conveyor elements, dust clogging of roller supports, and belt ruptures. The study emphasizes the issues with dynamic loads that result in conveyor element failures, clogged roller supports from dust, and ruptured belts. A review and analysis of studies on existing technologies showed the impact of design features on the productivity and quality of grain transportation. Modification of the rollers on the ascending branch of the working body of the belt reduces grain losses on both sides when slipping on the drive drum.

“…Therefore, fatigue failure is also considered in this study because it is an important design consideration that ensures the durability of a mechanical structure. Recently, FE-SAFE is increasingly being used to estimate the fatigue life of mechanical components utilizing the stress distribution obtained from FEA software such as ABAQUS and ANSYS [30][31][32][33]. Thus, in this study, topological optimization was used to optimize the blade geometry and a traditional FE-SAFE-based approach was utilized to estimate the fatigue life of the shredder blade.…”

There is an increased interest in designing cost-effective lightweight components to meet modern design requirements of improving cost and performance efficiency. This paper describes a significant effort to optimize the medical waste shredder blade through weight reduction by increasing material efficiency. The blade computer-aided design (CAD) model was produced through reverse engineering and converted to the finite element (FE) model to characterize von Mises stress and displacement. The obtained stress characteristics were introduced into the FE-SAFE for fatigue analysis. Furthermore, the FE model was analyzed through topological optimization using strain energy as the objective function while implementing the volume constraint. To obtain the optimal volume constraint for the blade model, several 3D numerical test cases were performed at various volume constraints. A significant weight reduction of 24.7% was observed for the 80% volume constraint (VC80). The FE analysis of optimal geometry indicated a 6 MPa decrease in the von Mises and a 14.5% increase in the fatigue life. Therefore, the proposed optimal design method demonstrated to be effective and easy to apply for the topology optimization of the shredder blade and has significantly decreased the structural weight without compromising the structural integrity and robustness.

The steering arm has recently been frequently broken in a kind of mining truck with Macpherson suspension. To accelerate replacing the broken parts and minimize the economic cost, a fast calculation method for improving the steering arm is proposed in this paper. In this method, the forces on the steering arm are calculated by quasi-static analysis under a low vehicle velocity. Dynamic characteristics of the tire and road are partly included by considering the ranges of the rolling resistance coefficient and friction coefficient from the empirical values, which determines the torque on the steering arm under extreme conditions. The rigid–flexible coupling model for the left steering mechanism in ANSYS Workbench is established and solved to obtain the distribution stress on the steering arm under extreme conditions. Then, the reliability of the simulation results based on this fast calculation method is verified by the experiment. After determining an improvement scheme considering the economic and time cost, the satisfactory strength is obtained. The results illustrate that the strength of the improved steering arm has nearly doubled. Finally, the effectiveness of the improved steering arm is demonstrated by the users’ feedback after it is manufactured, installed, and used.
