Axle housing fatigue testing machine | a sharp weapon for durability testing of commercial vehicle axle housing, to build the safety bottom line of the whole vehicle.

Axle is the core load-bearing component of commercial vehicles, and the bending stiffness and fatigue durability of axle housing directly determine the driving safety of vehicles under heavy load conditions. The traditional road test cycle is long, the cost is high, and the environmental interference is great. Therefore, the standardized fatigue bench in the laboratory has become the urgent need for R&D and quality inspection of automobile enterprises, parts factories and testing institutes. Jinan Power Collar Testing Machine Two-channel axle housing fatigue testing machine, with dual-channel synchronous coordinated loading, accurately simulates the alternating load of real vehicles, and completes the static stiffness and fatigue life test of axle housing for millions of times in one stop, providing a complete set of solutions for axle research and development and factory inspection. 1. Core uses of the equipment: the full coverage of the two core tests is specially developed for all kinds of truck axle housings, which is suitable for the full range of axle housing models of YTA35/YTA40/YTA55, and is compatible with the static and dynamic mechanical testing of building materials and large parts: the static test of vertical bending stiffness is loaded slowly and step by step, and the force-displacement curve is collected to accurately measure the static stiffness and ultimate bearing strength of the axle housing and verify the structural design margin; The vertical bending fatigue endurance test is loaded with alternating cycles of 0.1-10Hz, which simulates the long-term stress of vehicle bumping pavement, automatically records the number of cycles, and judges the fatigue life of axle housing and the risk of weld cracking. It completely matches the QC/T533 industry standard for fatigue test of automobile driving abutment, and the data can be directly used for type inspection and new product development verification. Second, the five core modules of the whole machine, the imported accessories are stable and durable. The whole set of equipment adopts modular integrated design, and the core components of hydraulic, sensing and control are selected globally. The 24-hour uninterrupted fatigue test can also stabilize the output without frequent downtime. Double 1000kN servo actuators | Dual-channel synchronous loading core Two independent loading units, each with a maximum load of 1000 tons, and two-point synchronous pressure perfectly restores the real stress point of the wheel. The piston rod is polished with hard chrome and matched with the seal imported from Britain, so that it does not leak oil after millions of reciprocating movements; Built-in high-precision displacement sensor, American World Force Sensor, the error of force value and displacement measurement is very small. The ball joints at both ends are flexible and adjustable, and the tilting and rotating angles are suitable for the installation of different types of axle housings; It is equipped with hydraulic buffer limit to prevent the equipment from being damaged by over-stroke impact, which is more worry-free for long-term use. 180l/min servo hydraulic pump station | A steady power 75kw high-power servo motor with system pressure up to 21MPa, equipped with low-noise gear oil pump imported from Japan, with low running noise and long service life. It is equipped with multiple early warning protection for oil temperature, oil level and filter element blockage, and with external cooling water circulation system, the oil temperature can be controlled for a long time, which is suitable for normal batch inspection in factories. As the intermediate hub between the oil source and the loading unit, the relay pressure-stabilizing oil separator | Oil-way pressure-stabilizing purification transfer station is built with a precision 3μm filter and accumulator for pressure stabilization, which can not only filter the impurities in hydraulic oil, but also offset the pressure fluctuation in the oil path, ensure the synchronization of dual-channel loading without deviation, and greatly prolong the service life of the servo valve. Gantry High Rigidity Test Frame | A fixture is suitable for welding gantry reaction frames with various axle housing thickened steel plates, and with HT250 cast iron T-groove bottom plate, the fixture position can be freely adjusted back and forth, left and right. Equipped with exclusive detachable upper and lower fixtures, the YTA full range of axle housings can be quickly disassembled and switched, and there is no need to customize the tooling repeatedly. One device can detect a variety of mainstream products of enterprises, saving equipment procurement costs. All-digital intelligent control system | visual operation, novice can easily start dual-channel independent closed-loop control, and the mode of force control and displacement control can be switched with one button, with high synchronization of two loading channels and minimal phase error. Support sine wave, triangle wave, step static loading and other load waveforms, with Advantech industrial computer, the operation interface is fully visualized in Chinese. During the test, the force value, displacement and cycle times are displayed in real time, and complete curves and test reports are automatically generated. The data can be saved, printed and exported with one button, and the test records can be kept for a long time for product traceability. Third, the core advantages of the equipment, solving the pain points of industry detection, dual-channel synchronous loading: two-point synchronous force application, perfect reproduction of real vehicle working conditions, and test data more suitable for real driving scenes; Large load and wide travel: the maximum bearing capacity of a single channel is 1000kN, with a large travel of ±75mm, covering all kinds of axle housings of light, medium and heavy trucks; Imported core components: seals, sensors, oil pipes and oil pumps are selected from overseas famous brands, with low failure rate and long maintenance period; Multi-purpose flexible adaptation of one machine: large-scale parts and building materials can be detected by changing tooling, and the equipment use scene can be expanded; Full-automatic intelligent protection: automatic stop alarm in case of overstress, overtravel, abnormal oil temperature and filter plug, so as to avoid sample and equipment damage; One-stop turnkey landing: the whole machine is equipped with a full set of tooling, spare filter element and hydraulic pipeline, on-site installation and debugging+one-on-one operator training. Fourth, the whole process of caring service, the purchase of worry-free equipment belongs to a complete turnkey project, including the whole machine transportation, insurance, on-site installation and commissioning, on-site operation training, supporting hydraulic oil, a full set of test tools and taxes; Only the foundation of the workshop is not included, and the tooling expansion plan can be customized according to the size of the customer's workshop. Long-term after-sales guarantee: remote online rapid troubleshooting, perennial supply of original spare parts, annual on-site calibration and maintenance, eliminating worries about later use.
