A major challenge that railroads have always faced is the prevention of track failures. North American railroads have been inspecting track, their most costly asset, since the late 1920s. With increasing train traffic, higher speeds, and heavier axle loads, the importance of track inspection increases. While track is a fairly well-defined piece of steel, the test variables are significant and add a level of challenge. PZFlex can be used to project various flaws and faults onto the track structure to determine their effect on structural integrity. PZFlex theoretical modeling is also useful for training new inspection engineers to identify and categorize defects in rail structure.

PZFlex is an excellent choice for modeling piezoelectric systems and improving their performance. In the automobile industry, as in the aerospace industry, use of piezoceramics is widespread, and the potential for PZFlex to support their use is being explored. Piezoceramics are part of every component, from simple audible buzzers and knock sensors for engines to micro-machined accelerometers for deploying air bags and car alarms. They offer distinct advantages. For example, integrating piezoceramics with diesel injection systems produces more efficient diesel injectors that tailor fuel inflow. The new injectors consist of stacks of piezoelectric ceramic elements that expand instantly when electric current is applied. They allow more fuel to be injected more quickly, with greater atomization and more precise injection timing. They operate ten times faster than solenoids, performing up to five injections per cycle, with a single pilot injection at hot idle and multiple injections at partial load. Combustion noise is also substantially reduced.
