This work proposes a design process for customizing three-dimensional (3D) printed shoe insoles to improve an individual’s footwear comfort based on body weight index and activity requirements. The purpose of this research is that people with various types of feet can benefit from these customizable insoles. PolyFlex Thermoplastic Polyurethane (TPU) materials based on the Fused Deposition Modeling (FDM) technique were investigated in this study. Samples with different infill patterns (Triangle, ...

Medium pressure natural circulation boiler is a common heat exchange pressure device in industry. The object has complex characteristics such as MIMO, strong coupling and uncertainty. It is difficult to achieve ideal control effect by using traditional controller to deal with the change of working conditions. In this study, SIMATIC PCS7 is used as the controller, CFC and SFC are used to complete different control loop configurations, so as to realize the control of superheated steam flow, superh...

3D Printing is the trending technology in this generation and its usage is increasing day-by-day because it reduces cost of production. FDM (Fused Deposition Modeling) is one type of 3D printing which uses plastics in the form of wire like filament by an extruder for making 3D prints. But, by installing a pellet extruder instead of filament extruder reduces cost of printing process that is 1 kg of PLA pellets cost around 4€ while 1 kg of PLA filament cost around 22€; also, can print wide ranges ...

Wind load is the important factor influencing arc-extinguishing of arc. Establishing arc chain motion model of 35 kV parallel gap under wind load condition, the electromagnetic force, air resistance and wind force of a single arc element are analyzed by using the chain arc model. The arc motion parameters were solved. The arc anti-resistance and arc resistance are calculated; the criterion of arc extinguishing is defined; the arc burning time is calculated, and the arc burning time is obtained. ...

Carbon fiber-reinforced polymer (CFRP) large diameter hole drilling is certifiably not a broadly examined theme on account of their non-homogeneity and anisotropic highlights. In the scope of aerospace industrial uses of this material, thousands of holes have to be machined for purposes of assembly. The quality of this machined hole is influenced adversely by matrix grid cratering, thermal damage, spalling, surface delamination, and material debasement or fiber pullout. Among these different def...

Vehicle Dynamics is a compulsory course of vehicle engineering. At present, the teaching method is still dominated by teachers. There are some problems, such as insufficient engineering oriented teaching content, unable to mobilize students’ learning enthusiasm and so on, which cannot meet the training needs of “New Engineering” for engineers. Based on the concept of project teaching, this paper discusses the teaching content and teaching mode of Vehicle Dynamics, so as to improve students’ part...

In this paper, the front bumper of a certain model was simulated and analyzed in low-speed frontal collision. HyperMesh software was used as the pre-processor, LS-DYNA was submitted for simulation calculation, and HyperView was used as the post-processor to view the output results, so as to analyze the performance of the automobile front bumper in low-speed frontal collision. At the same time, the influence of different beam thickness on collision performance is compared under the same condition...
