Mode of Failure: Low cycle / High strength Fatigue. Crack propagated out of a casting discontinuity (gas porosity). Recommended Solutions; Smooth out by grinding the affected zone and install remotely controlled strain gauges to evaluate crack propagation. Metal stitching the crack
The article provides an analysis of use of heavyduty gear trains in the mining industry. It was revealed that it is necessary to create a dynamic model to calculate the acting stresses and durability in order to assess the dynamic parameters of the gear train. The article provides the results of use of Nastran software shell in terms of stressstrain behavior of the girth gear.
Innovative Fluid Power28 HELPFUL HINTS FOR ANALYZING BASKET CASES OThe last piece to fail will have the least amount of damage OTry to piece together the broken may seem like a waste of time but many times you will observe things which can help you determine the original cause of failure.
According to the structural characteristics of nonball mill, using the neural network theory to select and measure point, set the failure mode, analyze and determine the cause of malfunction. The newly developed fault detection system was used to simulative detect fault. Through data processing, the results can be directly derived which could be fed back into the design of nonball mill ...
