“…As shown above many approaches have been performed to provide static calibration of force platforms while dynamic calibration methods are not well established yet. Recently, the requirements for measuring dynamic forces have become more severe and varied in many industrial and research applications [88][89][90][91][92][93][94][95] so increasing the importance of the procedures for dynamic calibration of FPs [96]. Cappello et al [80] described a new technique based on a least-squares approach.…”

Nowadays force platforms are widely employed both for diagnostic purposes and for monitoring the execution of motor tasks such as stance, both static and perturbed, and gait. Moreover, even if a clinical assessment based on the knowledge of the forces the patients can exchange with the environment can be useful, some guidelines are needed to determine the practical limitations of the measurements for motion analysis and postural control. In particular, in situ calibration is a fundamental practice especially when the force platforms are either used as reference or are connected with other devices in the measurement chain. Several calibration procedures for force platforms have been proposed in the literature, some of them dealing with only one force component, others with all the force and moment components, and some research groups have also developed and tested some innovative devices or introduced some corrective equations, performing either static or dynamic calibration.

Paper deals with the regulation of the production process in the production of connectors for the automotive industry. Connectors are produced by spraying metal contacts with thermoplastic material using overmolding technology. For the analysis of the measurement system and the evaluation of the process performance, a qualitative characteristic was selected, namely the length dimension. The analyzed product is produced in an injection mold with two cavities. Products from individual cavities were analyzed separately. In the first phase, the analysis of the measurement system (MSA) was evaluated. In the second phase, process performance was evaluated using process performance indices. After the first phase, the measurement system was found to be satisfactory. In the second phase, it was found that the production process is not in very good condition. This means that the products produced in this process may show poor quality properties.

Ball bearings are key components in the gear transmission system. Supported ball bearings have great influences on the vibrations of the gear transmission system, especially the presence of the local faults. Although some reported works formulated the local fault in the supported bearings of the gear transmission system, the box and shaft were considered as rigid bodies. To overcome this problem, a rigid-flexible coupling dynamic model for a flexible gearbox with the supported ball bearings is developed, which cannot be described by the previous multibody models. The local fault in the supported bearing is described by a time-varying impact force model with a half-sine profile. The bearing clearance, flexible shaft, and box are considered in the rigid-flexible coupling dynamic model. The flexible shaft and box are formulated by a finite element method. The damping and contact stiffness in the bearings and gears are obtained by the previous methods in the listed works. The frictions between the mating components are formulated by the Coulomb friction model. An experimental study is applied to validate the rigid-flexible coupling dynamic model. The effects of the faults on the vibration transmission characteristics are investigated. The results provide that the local fault in the supported bearings will greatly affect the vibrations of the gearbox system. Moreover, it depicts that the vibration collection point for the defective bearings should be located at the same side to obtain better singles. This work can provide a more reasonable method for understanding the vibration transmission characteristics of the gearbox system with the local faults in the supported bearings than the reported multibody models.
