The paper deals with the monitoring the utility properties of the Al-Si coating which is applied by means of the hot dip coating on the ultra-high strength sheet 22MnB5 (martensite steel alloyed by boron). These sheets are used at the car-body design as the safety elements (bumpers, reinforcement posts). Individual parts are jointed also by the adhesive bonding methods. Evaluation of the material surfac (…)
Material flow optimizing is a process of finding an ideal level of material continuous movement at minimum cost, time consumption, energy, resources, employees or other criteria, such as length of transport distances, transport volume per time unit, size, capacity, capacity transport unit, transportation costs, use of loading space (volume), duration of transport and so on. The article describes the opt (…)
The paper deals with the analysis of shape deviations, causes of their origin and offers their brief overview. At the same time it points out the methods and possibilities of measurement of shape deviations by means of contact and contactless techniques. The paper focuses also on errors which might influence the measurement results. The main aim of the presented paper is practical measurement of shape d (…)
The paper deals with the design of a program for calculation of belt gears. The aim of the presented paper is to create the program for check and calculation of belt gears and consequent comparison of the results of the newly created program with the existing ones. The introductory part of the paper analyses the issue of belt gears, their categorization as well as the design and calculation of the belt (…)
The aim of this paper is to demonstrate the application possibilities at using diffusion bonding for creation the homogenous joints regarding their strength properties in comparison with the fusion MMAW method and with the parent material. Connection was carried out for low-alloyed bainitic steel 10GN2MFA that is designed for production shells and bodies of the primary steam-generators collectors which (…)
Reverse engineering is a technology that enables acceleration of data acquisition for CAD, CAM, CAE systems and thus greatly reduces the time of development, design and production of components. In general, reverse engineering technology can be considered as the conversion of analog data to digital data, which is further processed. Individual industries are still increasing their demands for accuracy, s (…)
University facilities often have extensive technical equipment for complex high-accuracy engineering calculations. These facilities strive to verify their results in practice. Such an opportunity arose in collaboration between the Centre for Forming Machine Design Research (CFMDR, Centrum výzkumu konstrukce tvářecích strojů) and the company TS Plzen, which focused on a new design concept for a hydraulic (…)
The article builds on the Euro-CASE Policy Paper published in 2013 on “Transforming Manufacturing’ A path to a Smart, Sustainable and Inclusive growth in Europe” [Euro-CASE 2013]. The industry is a very significant sector of the economy in the Czech Republic, it is crucial to follow new industry challenges as the upcoming digital revolution enables connectivity, automation, robotization etc. with the po (…)
Noise is one of the elementary and the most annoyance harmful civilizing factor in the present time. Possibilities of reduction noise load and protection against it are problematic. Air transport is currently involved to noise exposure significantly and effects on health are not only on flying personnel, passengers but also on people living around airports. Noise as the spreading of acoustic energy has (…)
This article deals with the definition of the optimal driver's seats properties on the examples of two systems with different kind of damping. In the first case use the springing support of driver seat uses a pneumatic spring and a telescopic hydraulic damper. In the second case, the damping effect is achieved by two pneumatic springs whose forces effect in the phase shifted by a throttle valve which is (…)
