During standard-compliant testing, a pendulum with a precisely specified mass, drop height, and geometry is released from a predetermined angle to strike and fracture a wooden specimen. Following the impact, the pendulum continues its upward swing to a certain height. The difference between the initial release height and the post-fracture height is utilized to calculate the primary testing parameter: the energy absorbed by the specimen during fracture. The calculated energy value is immediately displayed on the LCD panel in Joule. Note: the maximum capacity of 100 J is achieved when the pendulum is released from its maximum designed release angle.
\nThis dynamic design eliminates all lateral forces on the shaft bearings upon striking the specimen, ensuring that 100% of the pendulum kinetic energy is transferred directly to the specimen. By releasing the pendulum without a specimen in place and allowing it to complete an 11 half-cycle swing, the system automatically determines and calibrates the following parameters using the SELF-CALIBRATION menu option:<\/p>\n
Another key feature of the SIT-100 impact testing machine is the precise design of its frame and anvil, engineered for maximum rigidity and exceptional vibration damping. Due to optimization of the inertial torque, striker mass, and center of percussion (COP), vibrations are entirely eliminated upon striking the specimen.
\nThe machine executes calibration in compliance with the relevant standards using two methods:<\/p>\n
