基于环境舱温度补偿的转向高压油管冬季试验方法研究

Cold Weather Test Method Research of High Pressure Steering Oil Hose Based on Temperature Compensation in Environmental Chamber

通过对环境温度以及转向高压油管性能的分析,提出了基于环境舱温度补偿的转向高压油管冬季试验方法。该试验将低温环境舱与道路试验相结合,可以对错失自然环境冬季试验周期的相关零件进行有效验证。试验结果表明,利用环境舱温度补偿方法进行的转向高压油管冬季试验,与在真实低温环境下进行的冬季试验具有很好的相关性。

According to the analysis of the ambient temperature and the performance of the high pressure steering oil hose, a winter test method of the high pressure steering oil hose is proposed based on temperature compensation of environment chamber. This test method combines the low temperature environmental chamber with road test to verify the components which miss the winter test cycles. The test results show that the winter test of high temperature steering oil pipe with environmental chamber temperature compensation has good correlation with winter test under real low temperature environment.
