液压综合测试平台的研制

目前，调平腿（丝杆）等液压机构属于定制集成件，生产集成商不具备独立的集成件性能测试和功能验证条件，只能装机后随整机进行功能和性能测试，一旦出现故障，对产品的调试周期影响较大，而且故障分析、定位困难。为了实现液压机构装机前的性能测试和功能验收，文中研制了一种液压综合测试平台。该液压综合测试平台由液压系统、控制系统和机械结构系统组成，具有独立的驱动、加载、参数设置及测量记录功能，能够实现流量、加载力、扭矩、转速等参数的数字化设定与相关指标的测量及记录。文中提出的方法可为同类型设备的结构设计和优化提供参考。

Development of Hydraulic Integrated Test Platform

At present, the hydraulic mechanism such as hydraulic leveling leg (screw rods) belongs to custom integrated parts. However, the production integrators do not have independent performance test and function verification conditions for integrated parts, so they can only carry out performance test and function verification together with the whole machine after installation. Once a fault occurs, it will have a great effect on the debugging cycle of the product and it is very difficult to analyze and locate the fault. In order to carry out the performance test and function verification of custom integrated parts before installation, a hydraulic integrated test platform is developed. This hydraulic integrated test platform, which consists of hydraulic system, control system and mechanical structure system, has several functions including independent driving, loading, parameter setting, measuring and recording. It is able to set parameters such as flow, loading force, torque and rotation speed digitally and measure and record the related parameters. The approach proposed in this paper can be used as reference for the structure design and optimization of the same type of equipment.
