By using “Percent of Full Scale,” we can easily compare the performance
3. Theory. Following the analysis by Maranzano et al. [6], the trajectory of a sphere during impact with a load cell is described by Newton's second law of motion (Eq. (1)), where the forces exerted on the sphere include, the gravitational force, F grav, an elastic deformation force, F el, and a dissipative deformation force, F dis. (1) d dt mv sph = F el δ + F dis δ ̇-F gravThese triaxial load cells measure vertical forces as well as drag and side loads caused by the rapid acceleration of the wheels.

Interface Single Point Impact Load Cells (SPI) are sensors that accurately measure the impact force or load exerted on a single point. The Interface SPI and MBI are two models for platform scale single point impact load cells used for materials testing, impact testing, product durability testing, and quality control processes. Learn about the design and . Over two decades ago, another type of drop-weight testing machine was invented, which will be referred to as impact load cell.Weichert (Weichert and Herbst, 1986) is credited with the first design of the impact load cell for single-particle impact breakage testing. The design of the impact load cell evolved from the classic Hopkinson pressure bar (Hopkinson, . Short impact load cell (SILC) tests provide insight on the dynamic breakage behaviour of rocks. The measured impact force to first fracture of a rock specimen is used to calculate properties such as fracture toughness, tensile strength, and stiffness. To explore the repeatability and performance of the SILC test and verify the underlying assumptions for . Drop weight impact test calculations measure the toughness of polymers and composites used in many automotive and aerospace applications. Ensuring that these calculations are as accurate as possible is critical. .
