中空液压马达可靠性研究及设计
摘要
三轴转台为导弹导引装置提供运动平台,是导弹半实物仿真的关键设备,我所采用三轴转台的液压油源系统作为中空液压马达的试验装置。作为伺服动力驱动的一个重要元件,中空液压伺服马达在多轴液压仿真转台等领域具有重要的应用价值。由于中空液压马达三轴转台系统工程复杂、设计量大,采用合适的可靠性设计原理进行全面的可靠性设计,对验证整体设计方案的合理性以及不足之处有其必要性和现实性。
本文首先介绍了三轴转台系统整体结构设计,较详细地阐述了系统主要构件组成,例如:油源以及电控系统组成、内框和中框以及外框的组成、台座驱动系统以及计算机控制系统组成。根据整体设计方案,整个系统采取由油源、台体以及计算机控制系统三部分串联组成,而且各分系统内部主要构件也是采取串联结构的,因而对系统建立可靠性模型为串联模型。对系统的可靠性预计,根据系统可靠性指标,对系统采用元器件计数预计法进行预计,根据预计结果,可以很清楚发现系统的故障率并对系统故障率最大部分电控分系统提出可靠性改进方案与思路。可靠性预计是由单元到系统的预计,而可靠性分配则是由系统到单元的分配,通过采用串联系统比例分配法对系统以及关键构件进行可靠性合理分配,有效解决了其分配问题。对系统故障分析采用故障树分析FTA法以及失效模式影响分析FMEA法,对分析以及解决系统故障有直接帮助。在对系统可靠性设计保障方面引入了降额设计、冗余设计、容错设计以及可靠性验证试验等措施。
本文系统、全面地分析了中空液压马达系统可靠性设计三大主要环节:预计与分配、故障模式以及影响分析以及可靠性设计保障,有效解决了系统的可靠性设计问题。
The three axis table provides the movement platform for the missile guidance device, is the missile half in kind simulation essential equipment, I use the hydraulic pressure oil source system of the three axis table to take the spatial oil motor test equipment. As a servo power actuation important part, the center spatial hydraulic pressure servomotor has the important application value in multiple spindle hydraulic pressure simulation table. Because the center spatial oil motor three axis table system engineering is complex, supposes measures in a big way, uses the appropriate reliability design principle to carry on the comprehensive reliability design, to confirms the overall design plan the rationality as well as the deficiency has its necessity and the feasibility.This article first introduced the three axis table system overall construction design, in detail elaborated the system primary member composition, for example: oil source as well as electrically controlled system composition, inner edge and center frame as well as outer edge composition, pedestal actuation system as well as computer control system composition. According to the overall design plan, the overall system is composed by the oil source, the platform body as well as the computer control system three parts of series, moreover various subsystems interior primary member also adopts the series connected structure, thus the system reliable model established is the series connected model. Estimated to the system reliability, according to the system reliable target, uses the primary device to the system to count estimate law to carry on the estimate, according to estimates the result, may discover very clearly system failure rate and propose the reliability improvement program and the mentality to the system failure rate most majority of electrically controlled subsystem. The reliable estimate is from the unit to the system estimate, but reliability allocation then is from the system to the unit assignment, through using the cascade system proportion method of distribution carries on the reliable rational distribution to the system as well as the essential component, effective addressing its assignment problem. By the fault tree analytic method FTA as well as the fault model effective analytic method FMEA to the system fault analysis, has the direct help for analyzing as well as solving system failure .In the system reliability design safeguard aspect , fall volume design, redundancy design ,fault-tolerant design as well as reliability verification test and so on measure are introduced.This article systematically and comprehensively analyzes three big and key links of the center spatial hydraulic pressure motor system reliability to design: estimate and assignment, fault pattern as well as fault analysis as well as reliability design safeguard, in effectively address system reliability design question.
