“…The coefficients of h(x) can be calculated with equation (22), and the wear rate n(t) at time t can be calculated from the stresses with the load spectra given in Figure 11. Considering the switching properties of the load spectra, the degradation increment at each step can be obtained based on its probability distribution Dy t ;IG n t ð ÞDL, lDL 2 À Á .…”

“…Indeed, multi-stress ADT provides more opportunities of making the full use of information regarding the relationship between product degradation and lifetime-related stresses. Ge et al 22 studied the optimal test plans for constant-stress ADT with multiple stresses, and the testing profile (or called loading) was designed based on the uniform orthogonal test theory. Wang et al 18 proposed a simulation-based optimal design method for step-stress ADT with multiple stresses and multiple degradation measures.…”

Accelerated testing (AT) is an effective testing method for evaluating the reliability of highly reliable products. In many applications, such products are often subject to multiple stresses in actual working environments. Then, how to design the load spectra for multi-stress AT becomes a critical issue. In this paper, a new load spectra design method is proposed to overcome this challenge. Considering the properties of multiple stresses, a novel multi-stress loading matrix (MSLM) is modified to fully describe the load spectra in actual working environments and to generate the corresponding load spectra for AT. For illustration purposes, an inverse Gaussian (IG) process incorporating life-stress relationships is adopted to model product degradation under multiple stresses. A case study on a type of hydraulic piston pump is provided to demonstrate the use of the proposed method in guiding the load spectra design for multi-stress AT.
