Wire Mesh Support Systems for Low-Temperature Gasoline and Diesel Catalytic Converters (.pdf)
converters require some. density as well as the mesh's crimp height,. sort of support material to provide constant. courses per inch, needle count, number of. mounting pressure independent of vermiculite. strands, temper, surface profile and surface. expansion characteristics [7, 8]. This can

A closer look at Model Meshing
, are both constant throughout first-order tetrahedrons. The situation imposes a severe limitation on the capability of meshes constructed with first-order elements to model stress distributions of any real complexity. To make matters worse, straight edges and flat faces of the elements do not map

Overrange, A Crucial Rotary Torquemeter Parameter
poles and/or pistons and/or gear. meshes, etc. that generate complex forcing functions. Furthermore, drivelines consist of several. inertia's and torsion springs which resonate2 at one or more frequencies. As a result, even under. "constant load", real world driveline torque is never constant. Instead

More errors that mar FEA results
primitives but they can deviate further from ideal shapes. In a mesh of first-order elements, the displacement field is piecewise linear and continuous. The displacement field in each element is linear while strain (calculated as the first derivative of displacement) is constant. Consequently

FEA lets designers take first cut analyses
keeps mesh density constant and increases the polynomial order of the element-shape function. Reformulating a successfully run FEA model to a p-adaptive solution is less time consuming than remeshing the geometry. It's a powerful analysis tool but needs substantially more processing time than

Sometimes it pays to be eccentric
. HDF models, for example, are as thin as 11 mm and have torque ratings from 56 to 3,180 lb-in. with higher peak ratings. Dojen cycloidal speed reducers, from Mectrol Corp., Salem, N.H., maintain constant contact between all cam lobes and followers. This creates high shock-load capacity

Industrial Sensing the wireless way
," and "store-and-forward" represent the most common choices for acquiring sensor data. Periodic sampling serves in applications where a certain condition or process needs constant monitoring, as with temperature in a conditioned space or pressure in a process pipeline. Sensor data are acquired from remote
