A New Approach for Road‐Vehicle Vibration Simulation

A new approach for road‐vehicle vibration simulation is proposed and demonstrated feasible by testing with three express‐road vehicle‐vibration records, that is, record A, two‐wheel electric bicycle, 80% loaded, traveling on urban road; record B, median van, 50% loaded, traveling on urban road; and record C, minivan, 80% loaded, traveling on urban road too. This method decomposes the original signal into a series of approximate Gaussian‐vibration segments and a shock segment with high kurtosis by moving crest factor and one‐tenth peak‐value method. Simulate Gaussian‐distribution vibration one by one from the power spectral density (PSD) of each decomposed segments. The overall signal is simulated by concatenating of each decomposed Gaussian segment. The simulated signal has not only the same overall root‐mean‐square (RMS), duration as the original signal, but also has a similar PSD to the original signal, without incurring excessive acceleration levels. This allows an improved and more representative simulated input signal to be generated that can be use in the current generation of vibration table.     

Analysis of the fuzzy set literature using phrases

The topic of fuzzy set theory was examined using the occurrence of phrases in bibliographic records. Records containing the word fuzzy, were downloaded from over 100 databases, and from these records, phrases were extracted surrounding the word fuzzy. A methodology was developed to trim this list of phrases to a list of high frequency phrases relevant to fuzzy set theory. This list of phrases was in turn used to extract records from the original downloaded set, which were (algorithmically) relevant to fuzzy set theory. This set of records was then analysed to show the development of the topic of fuzzy set theory, the distribution of the fuzzy phrases over time and the frequency distribution of the fuzzy phrases. In addition, the field of the bibliographic record in which the phrase occurred was examined, as well as the first appearance of a particular fuzzy phrase.

The load separation andη pl development in precracked specimen test recordsdevelopment in precracked specimen test records

Load separation is the theoretical basis for the single specimenJ form and the incremental calculation ofJ-R andJ _M -R curves. It is based on the assumption that the load can be represented as a multiplication of two separate functions; a crack geometry function and a material deformation function. Until recently, the main experimental basis for such an assumption was the approximate agreement between the experimental results of the single specimenJ form and the energy rate interpretation ofJ in blunt notched bending geometries. The load separation assumption has been also implied in the growing crack records in order to develop theR-curve analysis. Both the crack geometry and material deformation functions were assumed to maintain their forms as the crack grows. Recently, an experimental study investigated the load separation in the test records of stationary crack specimens of different geometry, material, and constraint. The study showed that the load can be represented by a separable form for the entire plastic region except for a limited region at the early region of plastic behavior. Also, it was found that the load separation is not limited to a certain geometry, material, or constraint but it is a dominant property in the ductile fracture behavior of stationary crack specimens. The study also showed that the crack geometry function is a power law function. Henceη _pl is a constant equal to the power law exponent of the geometry function. The objective of this study is to investigate the extension of load separation to growing crack records. Sets of test records from three different materials are used in this study. For each material three or four precracked specimen test records and one blunt notched record are analyzed for the compact specimen geometry. The study will discuss the main condition to have a separable behavior in a growing crack test record. It will also construct the geometry and deformation functions for the materials studied, these functions are compared with those obtained from stationary crack records.     

近断层高架连续梁桥地震易损性与振动台试验研究

与远场地震动相比,近断层地震动长周期成分丰富、存在速度大脉冲效应,对柔性结构桥梁具有更高的震损能力。高架连续梁桥是一种常见的桥梁结构型式,距离断层较近时在地震中可能会发生更为严重的破坏。以一座典型四跨高架连续梁桥为例,对比了远场地震动和含速度脉冲近断层记录输入下的地震易损性规律,并通过缩尺模型振动台试验得到了典型近断层地震动输入下的动力响应。结果表明:与远场或设计地震动相比,含速度脉冲的近断层地震动输入下高架连续梁桥的地震易损性更高,在分析桥梁系统易损性时应综合考虑桥墩和支座的损伤指标,振动台试验结果验证了典型近断层地震动输入下高架连续梁桥动力响应更大。     

Quantifying the Non‐stationarity of Vehicle Vibrations with the Run Test

This paper investigates the applicability of the run test as a tool to quantify the statistical non‐stationarity of road vehicle vibrations. The run test was applied to the moving root‐mean‐square (RMS) time history of a number of vibration records measured from a variety of vehicle types, routes and vehicle speeds. The paper discusses the limitations associated with calculating the moving RMS of random signals especially with respect to the window width. When applied to the set of vibration records (with segments of inactivity removed), the run test indicates that every record is non‐stationary. A run ratio parameter was introduced to quantify the level of non‐stationarity, which shows that the result is sometimes dependent on the RMS window width. Further analysis correlating the run test results with the statistical distribution or the RMS indicates that the run ratio parameter has some merit in quantifying the level of non‐stationarity in road vehicle vibrations.
