The design of existing tribometers mainly focuses on normal contact and lubricant conditions and aims to evaluate the effect of the load, speed, and environmental conditions on the rubbing pair properties. The effect of the contact angle and variable speed on the rubbing pair properties is often not considered. In this study, a multidirectional adjustment tribometer is developed to evaluate the tribological behavior of cylinder liner–piston rings under dry sliding or oil lubrication conditions. The dynamic, specimen clamping, measuring, and control systems are redesigned according to the structural characteristics of the SKODA-SAVIN tribometer and special requirements of research on the net texture effect on tribological properties. Using LabVIEW software, a man–machine interface is designed to achieve converter control, data acquisition, and other functions. A fail-safe analysis is performed through reproducibility, comparability, and sensitivity tests. From the experiments, it is proved that the tester can provide more detailed, abundant, and reliable data for the performance testing and development of cylinder liner–piston ring materials.

现有的摩擦计的设计主要着眼于正常的接触和润滑条件，并旨在评估载荷，速度和环境条件对摩擦副性能的影响。通常不考虑接触角和变速对摩擦副性能的影响。在这项研究中，开发了一种多向调节摩擦计，以评估在干式滑动或油润滑条件下汽缸套-活塞环的摩擦学行为。根据SKODA-SAVIN摩擦计的结构特征以及对净结构对摩擦学特性影响的研究特殊要求，重新设计了动态，样品夹持，测量和控制系统。使用LabVIEW软件，设计了人机界面来实现转换器控制，数据采集，和其他功能。通过重现性，可比性和敏感性测试执行故障安全分析。通过实验证明，该测试仪可以为气缸套-活塞环材料的性能测试和开发提供更详细，丰富和可靠的数据。
