变刚度钢板弹簧加速寿命试验程序载荷谱编制
Test Program Load Spectrum Compilation for Accelerated Life Test of Leaf Springs with Variable Stiffness
摘要
Abstract
Considering characteristics of large deformation and nonlinear stiffness,a method of test program load spectrum compilation suitable for accelerated life test (ALT)of nonlinear leaf springs was presented.Based on the acceleration spectrum exposed to the leaf spring by road test, FEA method was used to obtain stress spectrum at any point.It is found that the amplitudes of stres-ses obey Weibull distribution,but the mean is not distributed as normal distribution or Weibull distri-bution.Based on the extrapolated spectrum,method of compilation and realization for bench test was studied.Compared to the results of road test,the compiled ALT program load spectrum is in accord-ance with the road tests.关键词
