A density detection system uses a magnetic force feedback actuator positioner to maintain a precise selected pressure between transducer wheels and the surface of a sheet of material as the sheet of material moves through a position between transducer wheel and lift wheel. Consequently, the antiquated mechanical/pneumatic springs/airbags of prior art ultrasonic density detection systems are replaced with a highly responsive magnetic force feedback actuator positioner capable of providing a precise and relatively constant force that can react to the introduction of a sheet of material, and/or variations in the surface of a sheet of material, extremely rapidly without the bounce/recovery oscillations associated with prior art ultrasonic density detection systems. Consequently, precise density measurements of an entire sheet of material can be obtained with unprecedented accuracy.

An inspection device includes a storage unit for storing a mechanical property inference model generated by machine learning based on mechanical property information and nondestructive inspection information of a fiber-reinforced first molded article region for which the mechanical property information and the nondestructive inspection information are known, the mechanical property inference model being configured to be input nondestructive inspection information of a second molded article region which is reinforced with reinforcing fibers for predicting unknown mechanical property information of the second molded article region. The inspection device acquires the nondestructive inspection information of the second molded article region; inputs the nondestructive inspection information to the mechanical property inference model; acquire the mechanical property information of the second molded article region predicted by the mechanical property inference model; and outputs the mechanical property information of the second molded article region.

According to one embodiment, a structure evaluation system includes a wave guide, a first sensor, a second sensor, and a calculation part. The wave guide is formed in a rod shape, is inserted into a hole that is formed at a predetermined depth from a surface of a measurement target, and has one end fixed to a deepest portion of the hole. The first sensor is provided at the other end of the wave guide at a position that is substantially the same as the surface. The second sensor is provided on the surface of the measurement target. The calculation part estimates a depth of damage occurring in the measurement target from the surface on the basis of a first detection value of an elastic wave transmitted to the measurement target which is detected by the first sensor through the wave guide and a second detection value obtained by an elastic wave which is detected by the second sensor.

An apparatus for scanning a cylindrical part is provided. The apparatus includes an ultrasonic transducer operable to emit ultrasonic waves into and receive ultrasonic waves from the part, with the ultrasonic transducer connected to a translation stage to move it up and down the part and around the circumference of the part.
