多轴载荷作用下减振器耐久性试验载荷谱编制
Load Spectrum Compilation of Damper Durability Tests Based on Multi-axial Loads
摘要
Abstract
Traditional damper durability tests only took the vertical loads into consideration and without unified standard for horizontal force loading,which led to inaccurate results.Given this situation,combined with actual user road load,this paper proposed a new method considering load spectrum with the multi-axial loads.With sine on sine method to compilation the load spectrum in order to analyze the failure reason of damper.The half-power bandwidth method and the maximum line velocity principle were employed to determine the low frequencies and high frequencies respectively,then establish durability bench test with multi-axial loads.The test results show that damper's failure lifes reduce greatly with the horizontal forces and the failure mileage consisted with survey results.It turns out that the spectrum compilation method may be more accurate to reappear the actual working status,and may provide technical support for the damper designs and improvements.关键词
