Large Area Dynamic Load Cell
No Thumbnail Available
The load cell is a transducer that is used to convert a force into electrical signal. This is indirect conversion which occurs in two stages. Through a mechanical arrangement, the force being sensed deforms a strain gauge. The strain gauge converts the deformation (strain) to electrical signals. Most industrial measurements of force are made with strain gauge load cell. The majority of today designs use strain gauges as the sensing element, either foil or semiconductor. Foil gauges offer the largest choice of different types and in consequence tend to be the most used in load cell designs. Strain gauge patterns offer measurement of tension, compression and shear forces. A vast number of load cell types have developed over the years; the previous designs simply used a strain gauge to measure the direct stress which is introduced into a metal element when it is subjected to a tensile or compressive force. The aim of thin project is to design large area dynamic load cell, Different concepts will be investigated using finite element analysis (ABAQUS) software, for example circular or rectangular plate with different supports to increase the plate stiffness will be investigated, after that the final selected concept will be design to determine its natural frequency, frequency modes that subjected to dynamic periodic load.
