本文详细推导了两种恒速传动装置(机械液压差动式及液压差动式)的数学模型——各组件与全系统的结构方块图,拟定了电模拟图,并在DMJ—3A电子模拟计算机上分析了两项主要性能——定载变速特性及定速变载特性。 与实测试验数据相比较,可以认为,文中提出的计算方法,具有较好的精度,达到了定量分析的要求,因而可供今后恒装性能设计参考。 本文针对具体研制产品,分析了结构参数对性能的影响,提出了分析意见。 文中所讨论的组件——油泵、液动机、滑阀、离心配重转速调节器,伺服作动筒等——的数学模型,具有普遍性。因此,本文提出的分析方法可进一步推广应用于其它机—电—液非线性复合系统。
In this paper, the mathematical models of two kinds of constant speed transmission devices (mechanical hydraulic differential and hydraulic differential) are deduced in detail. The structural block diagrams of each component and the whole system are elaborated, and the electrical simulation diagrams are drawn up. In the DMJ-3A electronic simulation The computer analyzed two main properties - fixed-load transmission characteristics and constant-speed load characteristics. Compared with the experimental data, it can be considered that the calculation method proposed in this paper has good accuracy and meets the requirements of quantitative analysis, so it can be used as a reference for constant assembly performance design in the future. In this paper, the specific product development, analysis of the structural parameters of the impact on performance, put forward the analysis of opinions. The components discussed in this paper - the mathematical models of oil pumps, hydraulic motors, slide valves, centrifugal counterweights, servo actuators, etc., are universal. Therefore, the analysis method proposed in this paper can be further extended to other organic electro-hydraulic nonlinear composite systems.
