The Four-Point High-Speed Bending Test Machine is specifically designed to simulate the bending resistance of materials or structural components under high-speed impact or transient loading. Its core lies in a high-speed actuator (typically servo-hydraulic or electromechanical) that applies a concentrated dynamic load to the center of the specimen at extremely high velocities.
The specimen is placed between two fixed lower support rollers and two movable upper loading rollers, creating a "four-point bending" stress state. This configuration ensures the specimen's pure bending section experiences a constant bending moment, allowing for precise measurement of its bending strength, modulus, energy absorption, and failure modes under high-speed conditions.
