Product Recalls and Its Assessment Significance,vacuum tube in the WWII created the bathtub curve. As NASA developed for the space shuttle program in the mid-sixties, FMEA, FTA and Weibull analysis for reliability testing today have been widely used in company. Now since Integrated Circuit (IC), transistor radio and TV in the late of 1960s are in宽敞 发表于 2025-3-27 04:43:31
Modern Definitions in Reliability Engineering, obtain the reasonable test data, mechanical engineer should understand the modern definitions that can be used. When product is subjected to repetitive stresses (sole factor) and there is design faulty in it, product will fail. However, there is no current methodology because product failures rarelConspiracy 发表于 2025-3-27 07:31:01

Structures (or Mechanisms) and Load Analysis,product is properly designed. As first step, there is a modeling of the dynamics systems that can be implemented by traditional method like Newtonian or bond-graph. The time response of mechanical system for (random) dynamic loads represents from its modeling. If simplified and counted as a sinusoid暗讽 发表于 2025-3-27 17:00:02
Fluid Motion and Mechanical Vibration,balances in the rotating parts or the movement of a tire on a gravel road. Unless isolated by proper stiffness design, system will create unwanted sound or waste energy. Ultimately mechanical system will fracture. To prevent it, engineers might find and correct the design faults of mechanical producAnguish 发表于 2025-3-27 21:45:48
Mechanical System Failures,gineer should figure out why the mechanical system failures will happen. Through the current reliability methodology engineer still doesn’t know whether product design overcomes (random) loads in its lifetime. For example, the failure of mechanical system like aircraft wing during a long flight canavulsion 发表于 2025-3-28 00:52:08
Parametric Accelerated Life Testing in Mechanical/Civil System,d considerably. Therefore, the best solution that can decrease the testing time and the sample size is the accelerated life testing that is based on the load analysis. If so, the weakest parts in product (or module) will be exposed. Engineer can solve the problematic designs by correcting them. To s夸张 发表于 2025-3-28 03:26:06

rglichen. Dabei zeigte sich keine statistisch signifikant unterschiedliche geschlechtsspezifische Beurteilung der Delikte für Männer und Frauen (siehe Tab. 15.1). In allen Fällen stehen die Gewaltdelikte eindeutig an oberster Stelle der Rangskala, diese “Taten” werden also als schlimmste verurteilt.
