10 results about "Shock testing" patented technology

Systems and methods are directed toward low temperature testing of motion, vibration, or force responses of test fixtures. For cryogenic shock testing, a test object can be secured on a test apparatus, such as a test fixture of a shock table. An elongated enclosure, such as a flexible tube, can be connected between the test fixture and a laser vibrometer, positioned orthogonal to a surface normal at a test region of the test fixture to enable light emitted by the vibrometer to be reflected from the test region back to the vibrometer. A flow of purge gas can be introduced into the tube, proximate the test fixture, to direct moisture away from the test fixture. The flow can prevent condensation or ice from forming on the surface of the test fixture at the cryogenic temperature. A shock event can be simulated, and the response of the test region measured by the laser vibrometer. The impact of the shock event on the test object can then be observed.

This invention discloses a temperature shock test chamber for electrical and electronic products, relating to the technical field of temperature shock testing equipment. Addressing the problem of poor isolation between the high and low temperature chambers in existing temperature shock test chambers, the following solution is proposed: a test chamber body with an experimental cavity on its inner wall, the inner wall of which has two air ducts; a basket located inside the experimental cavity, with two symmetrical sealing plates fixedly connected to its exterior; and an isolation frame located inside the experimental cavity, with a crossbeam on its exterior. This invention ensures effective isolation between the high and low temperature chambers during use, significantly reducing cross-current during basket switching between the two chambers, lowering the energy consumption of the temperature control system, improving temperature control accuracy, and enhancing the precision of test results.

This invention relates to the field of material performance testing technology and discloses a radar temperature shock testing device, including a temperature shock testing chamber and a testing cavity formed on the side of the chamber. The chamber is used for testing the physical and electrical properties of radar materials and components under temperature shock. An air outlet is provided on the inner side of the testing cavity, and an air guide assembly is provided on the inner wall to prevent high and low temperature airflows from directly blowing onto the radar under test. In this invention, a portion of the airflow enters the exhaust hood through the connecting shell, driving the fan blades to rotate and then being evenly discharged from three exhaust hoods in multiple directions. Another portion of the airflow causes the air guide cloths of different lengths to oscillate irregularly, further dispersing the airflow. This dual airflow guidance avoids the direct and forceful blowing of high and low temperature airflows onto the radar components, eliminating the influence of airflow interference on material performance testing, ensuring the authenticity and repeatability of sample test data under temperature shock, and is suitable for the testing and analysis of the thermal stability, fatigue characteristics, and electrical properties of radar materials.

The invention discloses a shock absorption performance testing device for a shock absorber, and belongs to the technical field of shock absorption testing, the shock absorption performance testing device comprises a testing mechanism used for testing the shock resistance and shock resistance of the shock absorber, and the testing mechanism is provided with a mounting mechanism used for mounting the shock absorber and a recording mechanism used for recording the shock condition of the shock absorber; in a vibration test, continuous and irregular bumping excitation on a real road surface is simulated through irregular and staggered bulges on the vibration wheel, and in an impact test, an instant and high-energy impact load is simulated through cooperation of a semi-eccentric wheel and a strong spring. The two excitation modes can more truly reflect the mechanical environment faced by the shock absorber in actual use, in addition, the shock absorber is simulated into an actual installation state in a test, namely the bottom is jacked up, the top is fixed, and the stress form of the shock absorber is consistent with the working state, so that the effectiveness and the reliability of test data are ensured.

This utility model relates to the field of temperature shock testing technology and discloses a multifunctional temperature shock test chamber with a protective structure. The chamber includes a main body, a lifting assembly fixedly connected to the top surface of the main body, and a basket fixedly connected to the bottom end of the lifting assembly. Several limiting strips are provided on both sides of the inner wall of the basket. This multifunctional temperature shock test chamber with a protective structure, through the arrangement of the basket, limiting strips, and placement assembly, allows for the placement of test samples according to their size on the placement rack during use. The adjusting rod is turned to fix the test sample in place by the limiting components, and the placement rack is inserted into the limiting strips to limit the position of the test sample. This prevents the sample from changing position or falling during multiple tests or comparisons of multiple samples under thermal shock, thus maintaining the stability of the sample.

The application discloses an impact test device based on electromagnetic loading. The device comprises a power supply system, an impact gun, a sensor data acquisition system and a clamp and bracket system. The impact gun converts the electric energy of the power supply system into electromagnetic force impact force to act on the to-be-impacted test piece fixed on the clamp and bracket system in the form of impact load. Before the test starts, the impact gun is in zero-distance contact with the to-be-impacted test piece, and the impact load is horizontally loaded in parallel to the ground. During the test, the sensor data acquisition system records the data of the impact force and deformation displacement of the test piece changing with time. After the test ends, the reaction force between the impact gun and the to-be-impacted test piece is consumed in the form of friction and temperature rise through the buffer system of the impact gun, so that the secondary impact on the to-be-impacted test piece is avoided. The energy storage capacitor and the charging voltage in the power supply system are variable. The application can solve the problems of complicated operation and single impact wave form of the current impact test equipment.
