Guard the chassis safety of construction machinery | ｜PWS‑1000CQ comprehensive performance test bench for driving axle housing, unlock the full-dimensional reliability verification of axle housing.

Construction machinery works at high frequency under harsh working conditions such as mines and construction sites. As the core component of the whole vehicle, the axle housing of the driving axle has to bear not only the huge self-weight of the whole vehicle, but also the alternating impact load brought by the road surface. Once the axle housing is deformed, cracked, and fatigued, the equipment will stop production, or serious safety accidents will occur.
The rigidity, static strength and bending fatigue performance of axle housing directly determine the service life and operation safety of the whole machine. Traditional road test has long cycle, high cost and difficult to reproduce the working conditions. A professional and reliable bench test equipment has become an essential hard-core equipment for parts research and development and quality control.
Today, I will take you into the comprehensive performance test platform of * * Jinan Power Collar Testing Machine PWS‑1000CQ drive axle housing, which is specially built for the drive axle housing of construction machinery, strictly conforms to the industry standard JB/T5928‑2014, and completes the whole project test of stiffness, strength and bending fatigue in one stop, so as to protect the product quality of the axle housing.
standard leads and fits the real test requirements of construction machinery.
This test bench is completely designed according to * **JB/T5928‑2014 "Technical Conditions of Driving Axle for Construction Machinery", covering all test items of vertical bending stiffness, vertical bending strength and bending fatigue of axle housing specified in the standard, and compatible with the fatigue test requirements of front axle of JB/T9828‑1999 wheeled tractor.
Stiffness test : Measure the deflection of axle housing under rated load and verify whether the deformation meets the standard limit;
Static strength test : Complete the verification of rated load, 1.5 times ultimate load and 2 times failure load, and check whether there is plastic deformation and cracking failure;
 Bending fatigue test * *: Simulate real alternating load and check the long-term fatigue resistance and durability of axle housing;
 Compatibility expansion * *: axle housings of loaders, excavators, bulldozers, road rollers and other construction machinery, and also adapt to automobile front axle specimens.
Specimen adaptation range: axle housing wheelbase * **1000‑3000mm** *, maximum outer diameter ≤500mm, and maximum bearing mass up to 25t. One equipment can meet the test requirements of various specimens with different specifications.
Hard core hardware, large tonnage and high precision loading strength
The test bench adopts * * gantry high-strength frame+modular unit * * overall layout, which is divided into five systems: mechanical loading, fixture, measurement and acquisition, servo control and safety protection. The static and dynamic loads are taken into account, and the loading is accurate and stable.
 Loading capacity (core technical parameters)
-Dynamic vertical loading: dual-channel 0‑300kN, accuracy 1% fs, satisfying fatigue alternating loading;
-Static vertical loading: double-channel 0‑1000kN, achieving ultimate strength failure test with large tonnage;
-Horizontal loading force: 0‑300kN, which supports the simulation of bi-directional bending composite working conditions;
-Dynamic loading frequency: 0‑10Hz, alternating impact of simulated reality vehicle;
-Static loading rate: 0.110 kn/s continuously adjustable;
-The actuator stroke is 0‑150mm, and the displacement accuracy is as high as * * 0.01 mm * *;
-The deformation measurement range is 0‑20mm, and the deflection measurement accuracy is ±0.01mm；;
-The positioning accuracy of the test bench is 1 mm, and the positioning of the specimen is reliable.
The hydraulic power unit is equipped with a 90kW servo oil source with a flow rate of 180L/min, and is equipped with multiple protections such as cooling, filtering, overpressure, overtemperature and liquid level to ensure the stable operation of the long-term fatigue test.
Modular tooling, efficiently adapting to multi-specification specimens.
The fixture adopts adjustable modular design;
-The wheelbase of the supporting base is 1000‑3000mm, which can be adjusted in a wide range to adapt to different axle housing spans;
-Hydraulic clamping mechanism, with controllable clamping force and buffer protection to avoid workpiece clamping injury;
-The middle part can be separated from the auxiliary support, and the specimen can be hoisted to protect it, and it will be automatically separated during the test without interfering with the stress and deformation.
There is no need to repeatedly modify the tooling, and it is quick to switch between different types of axle housings, which greatly improves the test efficiency.
Intelligent measurement and control makes the test simpler and the data more credible.
The system adopts * * industrial computer+servo controller two-stage closed-loop control architecture * *, supports * * manual/automatic programmed loading dual mode, and bid farewell to tedious manual duty.
Software core competence:
1. Visual parameter setting: one-key configuration of load, load holding time, loading rate and cycle times;
2. Multi-channel synchronous acquisition: load, displacement and strain are recorded synchronously, and load displacement and load-strain curves are output in real time;
3. Automatic standard judgment: the software automatically judges whether the stiffness and strength tests are qualified according to the national standard threshold;
4. One-key output of report: automatically generate PDF/Excel test report, and completely retain the original test data, which is convenient for R&D benchmarking and factory filing;
5. Support historical data query and backtracking, and the whole test process can be traced.

Whether it is the iterative verification of samples in the research and development stage or the batch sampling inspection at the factory, it can be easily handled.
Multiple safety protection to ensure the safety of man-machine and equipment.
Fatigue test Under the condition of large tonnage load, safety is the most important, and the whole machine shall establish a complete protection system:
The closed high-strength protective fence and the safety door are interlocked with the system, and the test cannot be started if the door is not closed;
Multiple emergency stop buttons, one-button unloading and shutdown under abnormal working conditions;
Hydraulic overflow overload protection and software load double over-limit protection;
Sound and light alarm for pressure, oil temperature and liquid level faults;
Load the mechanical anti-falling device of the cross beam to avoid the risk caused by the failure of the oil cylinder.

All-round protection, put an end to potential safety hazards in the test process.
