This invention discloses a cab suspension fatigue durability test bench and its testing method, belonging to the field of cab suspension testing technology. It includes an experimental controller, an experimental support platform, a lower suspension platform, a degree-of-freedom generator, an upper suspension platform, and a force distribution simulation unit. The lower suspension platform is located inside the experimental support platform, and multiple first hydraulic cylinders are fixed at intervals around the periphery of the lower suspension platform. The degree-of-freedom generator includes a lower flange fixed to the center of the top surface of the lower suspension platform. Multiple guide pillars are fixed on the lower flange, and a sliding disc is slidably mounted on each guide pillar. A limit nut is screwed onto the sliding disc, and a ball joint seat is fixed in the center of the sliding disc. This cab suspension fatigue durability test bench and its testing method can accurately simulate the load redistribution during vehicle roll and pitch, more closely reflecting the actual driving forces of a vehicle. The test conditions are comprehensive and highly realistic, and the test results have greater engineering reference value.

The application discloses a process-configurable refrigeration system experiment control method and system, each refrigeration device in the refrigeration system is configured with a separate instruction message queue and an instruction execution process, and the method comprises the following steps: obtaining an experiment process configuration file, wherein the experiment process configuration file comprises operations and sequences in an experiment process; recursively analyzing the experiment process configuration file to obtain operation instructions and refrigeration devices corresponding to the operation instructions which need to be sequentially executed; sending each obtained operation instruction to a corresponding instruction message queue of a refrigeration device, calling a driving interface by a corresponding instruction execution process, and executing the operation instruction. The application can realize automatic operation of an experiment process based on an experiment process configuration file, and realizes efficient interaction with a device control module through an integrated message queue and a cache mechanism in the operation process.
