With the characteristics of simple structure, good fabrication performance and stability, the disc strain gauge torque sensor is widely equipped in the collaborative robot to measure the modular joint output torque. The sensitivity and the stiffness are two important parameters of the torque sensor ...
As the core component of a swivel bridge, the spherical hinge structure exhibits complex mechanical behavior under high pressure, making it challenging to describe accurately through theoretical analysis or on-site monitoring. In this context, this paper
In the absence of such sophisticated design aids, the designer can be well served by full-scale testing with stress-coat and strain-gauge techniques. III.I Design for Human Factors Consideration of human factors is especially important in the design of frames and housings. In the automotive ...
The geometric stress concentration is determined by strain gauge measurements or by refined finite element analysis based on shell or solid elements. Fatigue design criteria for marine structures are based on two alternative definitions of load effects and the corresponding strength (SN-curves). This ...
Gauge signal post-filtering is then virtually useless. The strain gauge-instrumented projectile sensitivity is used to study the effects of small clamping pressure variations during the transverse impact study on shipbuilding steel plates. A second application deals with the impact of an automotive ...
A double-ended tuning fork (DETF) strain gauge that can be used for strain and force measurements is designed and fabricated in this work. The design of the sensor was augmented by an analytical model using the linear beam theory, by numerical simulations performed in COMSOL ...
(0.99) close to 1. The volume expansion of semiconductors at solidification was applied in the form of an isotropic eigenstrain induced by a virtual temperature change. As drawing a long fibre at constant velocity is a steady-state process, the liquid–solid interface remained at the same ...
However, it is still a big challenge for parametric design and precision manufacturing of the DIW-printed strain gauge due to the lack of universal analytical model and optimized process parameters. Here we propose an analytical model for designing widely used sandwich-structure strain gauges with ...
Displacements of the mass elements inside the tube wall allow for defining strains into the fibre structure. According to the Lamé description, the strain along the radial direction is obtained by solving \({\varepsilon }_{r}(r)=\frac{du(r)}{dr}\), whereas the strain along the azimuthal...
Three Linear Variable Differential Transformers (LVDT) measured the strain during the Emod tests instead of the strain gauges used by van den Heever et al. [22]. The LVDTs are evenly spaced around the circumference of the specimens with a rig attached to the specimens with a gauge length ...
