Load cells are force sensors, which are used in weighing equipment. The objective of this work is to develop MEMS based load cell. In this work two different load cell designs were simulated. First design is based on compressing a meander like polysilicon strain gage for the measurement of high forces up to 10kN. Second design is based on MEMS pressure sensor consisting of membrane, on which ...

High Pressure Processing (HPP) is a leading non-thermal food processing technology that is often cited as a major technological innovation in food preservation. Although it is very early to place this emerging technology among the list of breakthroughs in food processing, HPP has started to become a viable commercial alternative for pasteurisation of value added fruits, vegetables, meat, and ...

A problem of damage prediction in aircraft structure and its non-destructive evaluation is very important for aircraft structural health assessment. The analysis of the features of direct impact of thin-walled laminate component of aircraft was performed by COMSOL Multiphysics software. Mainly the GFRC and CFRC laminates were selected in form either thin separate plate or sandwich structure. The ...

NASA is funding the development of a high-fidelity fully superconducting machine sizing tool able to generate optimized designs based on thrust requirements and design constraints. Several mechanical challenges need to be overcome during the design of the torque transfer components. Reducing the conducted heat load requires the use of different materials in the torque path, which requires ...

Ball joints are widely used in many applications. This paper describes the contact and kinematic analysis of an Rzeppa type constant-velocity joint (CV-joint). Starting from a conveniently simplified 3D model, at fixed joint angle of 45°, a CV-joint made of all “generic steel” components has been studied. Considering only a “perfect” geometry (i.e. not affected by ...
