Radial run-out is caused by the tool being translated off the machine axis, still parallel. Radial run-out will measure the same all along the machine axis. Axial run-out is caused by the tool or component being at an angle to the axis. Axial run-out causes the tip of the tool or shaft to rotate off-centre relative to the base.
A load bank is a piece of electrical test equipment used to simulate an electrical load, to test an electric power source without connecting it to its normal operating load. [ 1 ] [ 2 ] During testing, adjustment, calibration, or verification procedures, a load bank is connected to the output of a power source, such as an electric generator ...
A rating plate on a machine carries information about its operational limits. The plate frequently contains the names of the machine and its manufacturer, so the rating plate is often called a name plate (hence the term " nameplate capacity " for a generator), although many devices carry separate nameplates and rating plates.
A proof test is a form of stress test to demonstrate the fitness of a load-bearing or impact-experiencing structure. An individual proof test may apply only to the unit tested, or to its design in general for mass-produced items. Such a structure is often subjected to loads above those expected in actual use, demonstrating safety and design margin.
Nearly all the load testing tools and frameworks follow the classical load testing paradigm: when customers visit your website, a script recorder records the communication and then creates related interaction scripts. A load generator tries to replay the recorded scripts, which could possibly be modified with different test parameters before ...
Load rejection in an electric power system is the condition in which there is a sudden load loss in the system which causes the generating equipment to be over-frequency.. A load rejection test is part of commissioning for power systems to confirm that the system can withstand a sudden loss of load and return to normal operating conditions using its governor. [1]
a): load paths based on U* index; b): von Mises stress distribution [2] In the image to the right, a structural member with a central hole is placed under load bearing stress. Figure (a) shows the U* distribution and the resultant load paths while figure (b) is the von Mises Stress distribution. As can be seen from figure (b), higher stresses ...
The surface plate is often used as the baseline for all measurements to a workpiece, therefore one primary surface is finished extremely flat with tolerances below 11.5 μm or 0.0115 mm per 2960 mm for a grade 0 plate. [2] Surface plates are a common tool in the manufacturing industry and are often fitted with mounting points so that it can be ...
