摘要
制动技术的发展对国防建设、航空航天技术研究以及农业工业技术的进一步发展都具有重大意义。基于液压节流耗能原理,建立描述波形器动态特性的非线性数学模型并进行数值仿真,同时对影响波形器性能的几个重要参数进行了讨论分析,探究如何通过有规律地对波形器参数进行调整,使所产生的波形幅值和脉宽符合冲击实验所需的脉冲波形要求并使末端平稳归零,以此来提高加速度波形的置信度。液压波形器的波形调节简单,实现了对波形器的多样化设计,可保证生产实际的需要。
The development of braking technology is of great significance to the construction of national defense,the research of aerospace technology and the further development of agricultural industry technology.Based on the principle of hydraulic throttling energy consumption,a nonlinear mathematical model describing the dynamic characteristics of the waveform device is established and numerical simulation is carried out.Meanwhile,several important parameters affecting the performance of the waveform device are discussed and analyzed,and how to adjust the parameters of the waveform device regularly is explored.The amplitude and pulse width of the generated waveform meet the requirements of the pulse waveform required by the impact experiment and the end is smoothly zeroed,so as to improve the confidence of the acceleration waveform.The waveform adjustment of the hydraulic waveform device is simple,which realizes the diversified design of the waveform device and can ensure the needs of actual production.
