According to the present disclosure, an electrode tab tensile strength test device is disclosed. The electrode tab tensile strength test device may include: a clamping member configured to pressurize an electrode tab of an electrode assembly; a driving member including a driving motor, and a gear member configured to convert driving force generated by the driving motor into linear motion, and configured to move the clamping member; and a sensor module connected to the clamping member and the gear member, and configured to change internal resistance based on a movement of the gear member.

Provided are a visible transparent soil model test box with an adjustable surrounding rock pressure and a manufacturing method therefor. The visible transparent soil model test box includes pressure plates, force transferring plates, bolt assemblies and pressure boxes. The model box is assembled by the bolt assemblies, and then transparent soil is poured into the box. During the pouring of the transparent soil, the pressure boxes are buried inside the transparent soil and at inner sides of a left pressure plate, a right pressure plate and an upper pressure plate. After the transparent soil is consolidated, nuts are screwed to push the force transferring plates and the pressure plates by pressure gaskets to move inward to squeeze soil mass, and the pressure is controlled through readings of the pressure boxes, thus achieving automatic regulation of the surrounding rock pressure.

A test fixture for a testing a vehicle seat mounting includes a first portion and a second portion separate from the first portion and having a fulcrum supported thereon. An energy absorbing member is attached to the test fixture first portion and extends around a portion of the fulcrum. The energy absorbing member is formed so as to have a first shape when the test fixture first portion and second portion are spaced apart less than a predetermined distance. The test fixture is structured so that movement of the second portion in a direction away from the first portion causes the fulcrum to slide along the energy absorbing member. Sliding of the fulcrum along the energy absorbing member plastically deforms the energy absorbing member into a second shape different from the first shape.

Provided herein are systems and methods for carrying out high-throughput quantitative measurements of bulk mechanical properties of soft materials. The systems include a centrifuge, solid particles, and sample wells. In the systems and methods, samples comprising solid particles embedded in soft materials contained within sample wells are centrifuged in a series of increasing centrifugal speed increments, and a bulk mechanical property, such as fracture stress or elastic modulus, of each soft material is determined by monitoring the centrifugal force needed for the solid particles to fracture the soft material in each of the samples.
