II. Main Functions of the Laboratory Bench
1. All hydraulic valves must utilize advanced Bosch Rexroth hydraulic components, with performance parameters fully meeting the syllabus requirements and industrial application standards, referencing design standards such as JB/JQ20233-88. The bench must be compatible with the existing equipment in the laboratory. The overlap dimensions are universal, hydraulic connectors are interchangeable, and the valve bottom oil block hooks match the existing equipment. A free one-time technical service is provided for older equipment, including but not limited to repair, cleaning, and maintenance.
2. The excavator mechanism is used as a supplementary actuator system. For durability, the excavator’s boom, arm, and bucket must not be made of hard plastic or plexiglass. Instead, they must be constructed of all-metal steel plates, scaled to exacting specifications, and featuring exquisite workmanship. (A demonstration video showcasing the excavator’s mechanical structure and operating process will be provided at the bidding site.)
3. The electrical control system must utilize the new-generation RLAY-OUT-1 integrated circuit board (an integrated circuit, not a data acquisition card). This board features over 10 built-in inputs and outputs, eliminating the need for complex wiring. This ensures a more stable overall electrical system and facilitates subsequent maintenance and troubleshooting.
4. The equipment offers a variety of control methods, integrating various control technologies, including mechanical control, relay control, PLC automation, host computer configuration control, and compound control.
5. The software enables visual simulation of hydraulic control circuits, directly reflecting the operating status of the hydraulic circuit, PLC operating status, and the internal structure of each hydraulic component. It also communicates directly with the host computer for real-time control of the hardware circuit. This multi-disciplinary system modeling hydraulic software enables multi-dimensional virtual design and assembly of integrated mechatronic systems. 6. The data acquisition system is efficient and stable, enabling intelligent data acquisition, analysis, processing, digital display, automatic curve generation, and real-time monitoring for digital valve characteristic tests and control experiments. The industrial simulation actuators involved must have an industrial simulation structure and an automatic fault detection and analysis system.
