In this study, an optimization analysis of the hydraulic gear pump cover with design of experiments and response surface method has been conducted. The sample of the solid cover of a hydraulic pump has been parametrically modelled. Structural strength analysis of the modelled hydraulic pump cover has been realized using finite element method. To prevent the concentration of stress on the hydraulic pump cover and to keep the stress values on the safe side, design inputs were not exceeded. According to the analysis results of this optimization study; the wall thickness of the hydraulic pump cover has been reduced. Finally, experimental tests were performed on hydraulic pump test setup, for verification of the simulation results.

“…Profile was measured accurately in [6], as shown in Figure 5.But it means that we must get the material object and should cut it in order to allow the accessibility of the measuring tool. However, it's hard for us to get the material for example in design stage and it will cause irreversible damage.…”

Abstract. Considering the nature and characteristics of construction waste piles, this paper analyzed the factors affecting the stability of the slope of construction waste piles, and established the system of the assessment indexes for the slope failure risks of construction waste piles. Based on the basic principles and methods of fuzzy mathematics, the factor set and the remark set were established. The membership grade of continuous factor indexes is determined using the "ridge row distribution" function, while that for the discrete factor indexes was determined by the Delphi Method. For the weight of factors, the subjective weight was determined by the Analytic Hierarchy Process (AHP) and objective weight by the entropy weight method. And the distance function was introduced to determine the combination coefficient. This paper established a fuzzy comprehensive assessment model of slope failure risks of construction waste piles, and assessed pile slopes in the two dimensions of hazard and vulnerability. The root mean square of the hazard assessment result and vulnerability assessment result was the final assessment result. The paper then used a certain construction waste pile slope as the example for analysis, assessed the risks of the four stages of a landfill, verified the assessment model and analyzed the slope's failure risks and preventive measures against a slide.

This paper presents a planar spur gear planetary transmission model, describing in great detail aspects such as the geometric definition of geometric overlaps and the contact forces calculation, thus facilitating the reproducibility of results by fellow researchers. The planetary model is based on a mesh model already used by the authors in the study of external gear ordinary transmissions. The model has been improved and extended to allow for the internal meshing simulation, taking into consideration three possible contact scenarios: involute-involute contact, and two types of involute-tip rounding arc contact. The 6 degrees of freedom system solved for a single couple of gears has been expanded to 6 ? 3n degrees of freedom for a planetary transmission with n planets. Furthermore, the coupling of deformations through the gear bodies' flexibility has been also implemented and assessed. A step-by-step integration of the planetary is presented, using two typical configurations, demonstrating the model capability for transmission simulation of a planetary with distinct pressure angles on each mesh. The model is also put to the test with the simulation of the transmission error of a real transmission system, including the effect of different levels of external torque. The model is assessed by means of quasi-static analyses, and the meshing stiffness values are compared with those provided by the literature.
