摘要:

为提高海上作业直升机液压助降装置的捕获快速性,设计了一种基于并联液压缸与链传动系统的液压驱动系统,并对其捕获性能开展研究。在分析液压助降装置捕获原理基础上,建立捕获过程动力学模型,据此探究蓄能器捕获压力、粗液压缸阻尼力、传动链张紧力、摩擦力以及液压油温度对捕获速度的影响机制,建立各影响分项的数学表征,揭示作用机理,并提出影响权重评价方法。对比试验结果表明,在常温工况下,粗液压缸阻尼力对捕获速度的影响最为显著,“释放-捕获”循环工作模式有助于提高捕获速度;而在低温工况下,液压油流动阻力成为制约捕获速度的关键因素。研究结果可为液压助降装置的作业策略优化与驱动系统设计改进提供参考。

Abstract:

To improve the capture speed of the shipborne helicopter hydraulic landing assist device, a hydraulic drive system composed of parallel hydraulic cylinders and chain drive systems was designed, and its capture performance was studied. Firstly, the operating principle of the capture process was analyzed, a dynamic model for this process was established. The influence mechanism of the capture speed was discussed, including the accumulator captures pressure, the nonlinear damping force of the parallel cylinder, the tension force in the transmission chain, frictional forces, and oil temperature. Subsequently, The mathematical representations of each influencing factors were established, the action mechanisms were revealed, and a method for evaluating their influence weights was developed. Experimental results show that, in typical temperature environments, the damping force of the parallel hydraulic cylinder has the most significant impact on capture speed. Additionally, the "release-capture" working cycle is beneficial for enhancing capture speed. Flow resistance plays a crucial role in capture speed in low temperature condition. The research results provide valuable insights into the operational strategy and optimization design of hydraulic landing assist devices.
