摘要
高压气动电磁阀在船舶柴油机起动系统中有着至关重要的作用,其响应特性是保障柴油机可靠和迅速起动的关键因素之一。首先,基于电磁有限元仿真软件ANSYS Maxwell对船用柴油机起动电磁阀的响应时间进行仿真分析;其次,采用国际标准ISO 12238和电磁阀阀芯位移试验验证优化前后仿真模型的精确度。结果表明,电磁阀在工作电压24 V和气隙1.1 mm时,开启和关闭响应时间分别为31.3 ms和43.3 ms。最后,通过Maxwell软件自带的参数化等功能进行了性能优化设计,研制了气动电磁阀专用试验系统并开展了性能试验;结果表明电磁阀在工作电压为28.8 V时,电磁阀开启响应时间加快5.9 ms;在5个500匝线圈并联时,电磁阀开启响应时间加快16.3 ms,满足船舶柴油机起动系统要求。
The high-pressure pneumatic solenoid valve is critical to the marine diesel engine starting system.Its rapid response is crucial to reliable diesel engine starting.The study used ANSYS Maxwell software to simulate and analyze the response time of the solenoid valve.Secondly,international standard ISO 12238 and solenoid valve spool displacement test are used to verify the accuracy of the simulation model before and after optimization.Results show that the solenoid valve's response time is 31.3 ms and 43.3 ms at 24 V and the gap is 1.1 mm.The researchers optimized the solenoid valve performance using the Maxwell software's features before developing a special test system to evaluate its performance.The tests show that operating at 28.8 V,the opening response time is 5.9 ms faster.When five 500 turn coils are connected in parallel,the opening response time of the solenoid valve increases by 16.3 ms.
