Manual wheelchair users suffer shoulder pain and injury in the long term because of unconscious overuse. The ‘SENSEWHEEL’, which interposes three identical load cells between pushrim and rear wheel, measures the three components of pushing force Fx, Fy and Fz, and axial torque Tx applied at each load cell. Strain gauges were located on a diaphragm forming one face of the load cell. The ...

A solid oxide fuel cell (SOFC) is composed of four layers (anode, electrolyte compatibility layer and cathode) of different ceramic materials. The anode layer is produced by tape casting, the remaining layers are deposited by screen-printing. The layers are sintered together at high temperatures. During heating up and cooling down (manufacturing process), stresses are generated in the layers due ...

Microwave drying of foodstuffs is a complex interplay of mass, momentum, and energy transport coupled with large deformation of the solid. To be able to better understand the microwave drying process, a fundamentals-based three dimensional (3D) multiphase porous media based model is developed to simulate the microwave drying process. An elaborate experimental system comprising of infrared ...

COMSOL Multiphysics® has been used to predict the magnetic fields, eddy current, lorenz forces and stresses during a disruption for the new Advanced Outer Divertor for the Alcator C-Mod tokamak. A tokamak is used to study magnetic confinement of plasma for fusion, and a disruption occurs when the plasma decays, rapidly losing all of its current. COMSOL has been used to recreate the fields ...

Conductive Composites such as carbon fiber reinforced composites are increasingly used in safety critical aerospace applications. The catastrophic macro structural failure of composite structures initiates from a micro level failure event such as fiber breaks. The ability to detect damage early on can improve the safety level and reliability of composite structures. A multilevel self-sensing ...

The mechanical simulation and analysis of the cantilever-to-anchor configuration for an out-of-plane structure used in transducer applications is reported. The polymer-based Buckled Cantilever Plate “BCP” structure, gives the ability to orient an active device from a horizontal to a vertical position, once assembled. In this paper we compare four different cantilever-to-anchor configurations: ...

Introduction: Solver section of FEA plays a very important role; it takes the input from the preprocessor and solves millions of equations using numerical methods. Capability of any analysis tools can be measured based on the solver. Understanding the nature and operation of various structural solid mechanics solvers is the interest of the present study. Results: Contact pressure is ...

In this work, we present the performance analysis of novel micro machined Piezoresistive fluid flow pressure sensor using COMSOL Multiphysics. The principle of the sensing mechanism is based on the deflection of four sensing layers embedded on a thin membrane. The fluid passes through the layer causes the deflection of the sensing layer which measures the pressure of the fluid. The following ...

Predicting the physical properties and performance of carbon and graphite materials based on the microstructure of the finished material is a challenging endeavor. This paper discusses the process and workflow for measuring and analyzing the pore structure of graphite by combining advanced CT image technology with Simpleware’s ScanIP™ software. A stack of scanned CT images are imported into ...

The key issues of the Fraunhofer Institute for Solar Energy Systems are research and development of solar technologies for the fast growing market of solar energy. This paper presents examples of the usage of COMSOL Multiphysics: The ingress of water is a serious reason for the degradation of photovoltaic modules which can hardly be measured using experimental approaches yet. Therefore, a ...
