摘要

为了弥补陆基机舱实验室科研实验和教学的不足,采用B/S模式设计开发了模拟科研实验、教学和操作过程的仿真系统,并设计了模拟主推进柴油机推进特性的算法。进行了大量的实验,在实验室中得到了主机输出功率与燃油消耗率的关系曲线。采用Apache JMeter对部署在大连海事大学云上的仿真系统进行压力测试。结果表明,在试验条件下,样品请求的平均响应时间为330 ms,远远优于设计标准2 s。所有请求均无异常响应,各项指标完全满足项目组要求。该仿真系统填补了全景交互技术在轮机工程教育中应用的空白,为海事院校实验室探索“智能+”实验教学模式提供了参考。

Simulation Experiment and Teaching Research of a Land-Based Ship Engine Room
In order to make up for the shortage of scientific research experiments and teaching in land-based engine room laboratory, a simulation system is designed and developed using B/S mode to simulate scientific research experiments, teaching and operation processes, and designed algorithms to simulate the propulsion characteristics of the main propulsion diesel engine. A large number of experiments were carried out, and the relationship curve between output power and fuel consumption rate of the main engine was obtained in the laboratory. Apache JMeter was used to test the pressure of the simulation system deployed in Dalian Maritime University Cloud. It is found that under the test conditions, the average response time of sample request is 330 ms, which is far superior the design standard of 2 s. There is no abnormal response to all requests, and all indicators fully meet the requirements of the project team. The simulation system fills the gap in the application of panoramic interactive technology in Marine engineering education, and provides a reference for the exploration of "intelligent +" experiment and teaching mode in maritime university laboratories.
