Numerical analysis of cast partials using the finite element method

This paper discusses issues related to numerical analysis of arch cast partials. For this purpose the functional analysis of such prostheses was carried out, particularly with great emphasis put on factoring in loads and strains to which they are exposed. The method of finite elements was used to carry out a numerical analysis

Cast partials analysis using a proprietary test station

This paper discusses issues related to arch cast partials. Functional analysis of such prostheses was carried out, factoring in loads and strains to which they are exposed. Consequently, a test station was designed for measuring model prosthesis strain under dynamic load

Measurement system for testing the alar cast partials

The paper presented the issues related to the study of the alar cast partial. For this purpose, the author’s test station with a dedicated measurement system (with particular emphasis on its dynamics)

FEM analysis of arch cast partials

This paper presents FEM analysis of arch cast partials. Functional tests of such prostheses were carried out. Loads and strains they are subject to were taken into account. An original, proprietary test stand was devised to test cast partials

Automatic system for measuring shifts and deformation of dental prostheses

The paper presented a multi-purpose system for testing of dental prostheses within the static and kinematic conditions as well as the conditions of its stability quick analysis. The common goal of prosthetics specialists is to define biomechanical criteria shaping the restorations to protect the existing state of the biological substrate [1]. In prosthesis biomechanics, the gingival soft tissue, as substances with heterogeneous properties, are difficult to individual assessment of the value, direction and duration of the occlusion forces transmitted by the prosthesis in the life cycle [2]. More predictable are static or kinematic behaviors, reflecting the mechanical states of prosthesis design with designed shape and material properties which are possible to determine. However, static measurements of dentures do not reflect their work in natural conditions [3], and can only designate the values of selected parameters (deflection, stress) during the reference of constant load values. The article presents the author’s research stand for kinematic loads testing, which are similar to natural ones during shredding of food. The results of stress and strain of denture prosthesis, identified during laboratory tests, will be used to verify the mathematical models of dentures during kinematic forces

Analysis of the Operation Process of Vehicles Equipped with Telematic On-Board Systems

Modern vehicles are equipped with telematic on-board systems, which connect electronic devices between them. The sent data are among others used to control systems and devices. They also have a certain operational potential. They can, indeed, also be used to rationalize the technical service of the vehicle fleet. This publication presents the author’s graph of the operation process, including the monitoring of the vehicle fleet. The application of the presented approach will contribute to the improvement of the value of certain vehicle reliability and operation indicators

Metodyka modelowania poziomu bezpieczeństwa systemów ochrony peryferyjnej

Bezpieczeństwo obiektów transportowych, jako obiektów o charakterze strategicznym i zaliczanym do infrastruktury krytycznej, zależy od skuteczności zastosowanych poszczególnych systemów bezpieczeństwa. Systemy te powinny wzajemnie się uzupełnić, tak by skuteczność wykrycia zagrożenia była możliwe maksymalna przy założonych warunkach początkowych. Dlatego też stosuje się różnorodne rozwiązania. W artykule ukazano wykorzystanie różnych systemów ochrony peryferyjnej do ochrony obiektów. Zaprezentowano także metodykę modelowania poziomu bezpieczeństwa systemów ochrony peryferyjnej.Safety of transport objects, as objects of strategic character and belonging into a critical infrastructure depends on the effectiveness of used various security systems. These systems should complement each other, so that the effectiveness of threat detection was possible maximum at the assumed initial conditions. Therefore, different solutions are used. In the article is shown the use of different systems of peripheral protection for objects protection. It also presents a methodology of modelling the level of security of systems of peripheral protection
