The invention discloses a device and method for typical damage simulation of cable-stayed bridges, wherein the device for typical damage simulation of cable-stayed bridges includes five sub-systems: girder system, cable system, pier tower system, load system, and measurement system. System, main girder system: used to simulate the typical damage condition of the main girder of the cable-stayed bridge; cable system: used to simulate the typical broken cable damage condition of the cable-stayed cable; pier tower system: used to fix the main girder system and the cable system ; Load system: used to provide different static load conditions; Measuring system: used to measure the cable force of the cable system, the internal force of the main beam in the main beam system, and the stiffness of the main beam in the main beam system. The invention can effectively obtain the performance degradation rule of the cable-stayed bridge under typical damage, has simple structure, flexible operation, clear stress and wide application range.

The invention discloses a monitoring pipe and vacuum film connecting structure and a connecting construction method in soft foundation treatment. The connecting construction method includes the following steps: vertically drilling into foundation soil, burying the lower end of a monitoring pipe in the foundation soil, and enabling the upper end of the monitoring to be higher than a sand cushion layer; coaxially burying a sleeve outside the monitoring pipe, enabling the lower end of the sleeve to reach a foundation treatment layer, and enabling the upper end of the sleeve to be flush with or lower than the upper end of the monitoring pipe; laying a vacuum film on the sand cushion layer, enabling an opening of the vacuum film to penetrate the sleeve, and connecting the vacuum film with the four sides of the sleeve in a bonded manner; pouring clay slurry in a gap between the sleeve and the monitoring pipe, and enabling liquid level of the clay slurry to be flush with or higher than the surface of the sand cushion layer; cutting off the sleeve and the monitoring pipe after settlement of the foundation treatment layer is completed, and using a surcharged material to backfill the gap between the sleeve and the monitoring pipe densely. The monitoring pipe and vacuum film connecting structure and the connecting construction method have the advantages of simplicity in material, flexibility in operation and high sealability.

The invention discloses a hydraulic control system for a helicopter ground integrated test bench, and belongs to the technical field of helicopter tests. The system comprises an upper computer, an analog quantity I / O module and a steering engine controller; the upper computer is used for inputting an instruction and has a display processing function, the analog quantity I / O module is used for performing digital-to-analogue conversion, and the steering engine controller is used for receiving data transmitted by the analog quantity I / O module and controlling a main steering engine and a tail steering engine. The hydraulic control system for the helicopter ground integrated test bench further comprises a hydraulic system, a hydraulic pump in the hydraulic system serves as an accessory of a main speed reducer, an output shaft of the accessory of the main speed reducer is driven by an engine, the hydraulic pump is connected with the main steering engine and the tail steering engine through valves and pipelines, and the main steering engine, the tail steering engine and the hydraulic system all adopt airborne parts. According to the hydraulic control system for the helicopter ground integrated test bench, the real working condition of the helicopter hydraulic control system can be better simulated, the helicopter hydraulic control system can be better assessed, and meanwhile it is guaranteed that data of other test projects are truer and more effective.

The invention discloses hardness (stiffness) automatic detecting equipment for rubber shoe upper synthetic cloth. The equipment comprises a base, and is characterized in that an inlet support and an outlet support are arranged on the base in parallel in a spaced mode, an infrared emitter is arranged on the inlet support, and an infrared receiver is correspondingly arranged on the outlet support; a force applying sleeve is arranged in the middle of the position above the connecting line of the inlet support and the outlet support, and a movable force applying rod is mounted in the force applying sleeve; traction equipment is mounted on the outer side of the outlet support. According to the hardness (stiffness) automatic detecting equipment for the rubber shoe upper synthetic cloth, the uniformity of adhesive cement at each point of the cross section of the whole synthetic cloth can be continuously detected, a data-driven and standard detecting result is formed, therefore, the stiffness of the synthetic cloth can be controlled within an optimal range, and high-quality rubber shoes can be conveniently produced.
