4-position long stroke reciprocating bench

The workstation long stroke reciprocating platform is a testing equipment designed for large components or long-distance reciprocating motion requirements, widely used in fields such as automotive chassis, rail transportation, engineering machinery, and construction machinery. Its core function is to simulate the long stroke reciprocating motion of components in actual use (such as the long stroke extension and contraction of automotive suspension systems, the reciprocating pushing and pulling of hydraulic cylinders in construction machinery), and through multi station parallel testing, accurately detect key indicators such as motion accuracy, fatigue life, and friction loss of components, providing data support for the research and development, quality verification, and reliability evaluation of long stroke reciprocating components. It is a key equipment to ensure the stable operation of large mechanical systems.

From the perspective of device construction, the core consists ofMulti station long stroke drive system、Heavy duty load-bearing platform、Precision load and displacement control module、Status monitoring componentandIntelligent Data Collection SystemComposition. The standard configuration for multi station design includes 2-6 independent testing stations (expandable as needed), each equipped with a high-precision linear drive mechanism. The stroke adjustment range can reach 500-5000mm, meeting the requirements for long-distance reciprocating testing; The drive system adopts servo motor combined with precision gear rack or ball screw transmission, and the reciprocating speed can be accurately adjusted within the range of 0.01-1m/s. The motion positioning accuracy reaches ± 0.1mm, ensuring stable and error free long stroke motion; The heavy-duty load-bearing platform is made of high-strength steel welded together, with a single station bearing capacity of up to 500-5000kg, suitable for large components such as automobile frames and engineering robotic arms; The precise load control module applies dynamic or static loads of 1-500kN through hydraulic or servo loading systems, with a loading accuracy of ± 1% FS, restoring the actual working force state of the components; The state monitoring component integrates displacement sensors, force sensors, vibration sensors, and temperature sensors to monitor the real-time motion parameters and operating status of the components; The intelligent data acquisition system can synchronously record displacement, velocity, load, vibration, temperature and other data of each workstation, with a sampling frequency of 100Hz, data error less than 3%, and can automatically generate fatigue life analysis reports.

The core advantages of this device lie in "long stroke precise simulation" and "multi station efficient testing". Compared to conventional short stroke reciprocating equipment, its stroke range is increased by 10-50 times, which can truly reproduce the long-distance reciprocating working conditions of large mechanical components (such as the extension and retraction of excavator boom and the long stroke switch of subway doors), and the detection data is more in line with actual usage scenarios; Multi station parallel design can simultaneously test components of different specifications or the same batch, increasing testing efficiency by 2-5 times compared to single station equipment, significantly shortening the research and quality inspection cycle for large components. In addition, the device supports custom motion programs, which can simulate various long stroke reciprocating modes such as constant speed, variable speed, and intermittent. It can also superimpose composite working conditions such as vibration and impact, further expanding the testing range.

In practical applications, equipment functions cover key areas: in the automotive industry, testing the long stroke reciprocating fatigue life of automotive suspension systems and optimizing chassis shock absorption performance; In the field of rail transit, detecting the reliability of long-distance switch mechanisms for subway or high-speed rail doors to ensure driving safety; In the field of construction machinery, evaluate the long stroke reciprocating wear and fatigue strength of excavator hydraulic cylinders and loader arms to improve equipment durability; In the field of construction machinery, testing the long-distance reciprocating motion accuracy of tower crane telescopic arms to ensure stable lifting operations; In the field of scientific research, performance research is conducted on new long stroke transmission components, such as heavy-duty linear guides and large stroke hydraulic cylinders, to accelerate technological iteration.
