“…Seat Effective Amplitude Transmissibility (SEAT) is also an evaluation method used to assess the seat comfort through the Power Spectral Density (PSD) [38]. It is used to reflect the performance of seating suspension as a predictor of the comfort of the seated occupant.…”

Drivers of heavy trucks are exposed to large amounts of vibration which can lead to serious health risks. Many suspension systems/methods can be used to isolate these transmitted vibrations, such as vehicle suspension systems, cabin suspension systems and seating suspension systems. The central idea of the work is to identify the research gaps and raise our future research questions in this specific area. The novelty of this paper is proposing a model predictive controller for active vibration control of seating suspension systems. A systematic literature review of the existing work of the vibration control of seating suspension systems has been conducted. Various control techniques that are used in the seating suspension systems have been summarized and evaluated. This paper focusses on the biodynamic model of the driver and seat for the first step needed in the design of the seating suspension system. Then, it illustrates the different types of the system vibration controls and their performance evaluation methods. At the end, the paper details several active seating suspension systems including their actuation system structures and control algorithms which are used in the heavy vehicle trucks.

“…The factors that affect the comfort of clutch pedal include handling force, displacement, and angle. At present, to study the manipulation comfort, researchers usually focus on the layout of the control device, the design, and performance analysis of various components (Ciloglu, Alziadeh, Mohany, & Kishawy, ; Yuan, Jing, Jiang, Mao‐Gen, & Tang, ), the application of virtual simulation software, and human engineering theory (Y. Chen, Zang, & Hu, ; Porter & Gyi, ; Sharma, ; Teng, Li, Lv, Gong, & Chen, ; Thun, Lehr, & Bierwirth, ). But to a certain extent, these studies have ignored the multidimensional evaluation for comfort design, the establishment of a comprehensive index system, and the inconsistency of single evaluation methods.…”

Currently, studies of the manipulation comfort of agriculturalmachinery are mainly based on qualitative analysis and subjective evaluation. This study is mainly focused on the quantitative analysis and evaluation of the manipulation comfort of tractor gear-shifting. By taking various factors into account, a combined evaluation model and the corresponding indicator system were proposed based on the method of maximizing deviations. The data of pedal force and stroke length of the clutch were collected from eight different types of agricultural tractors, which were used as the basic data for subsequent analyses.Then, five evaluation methods, including principal component analysis (PCA), comprehensive evaluation based on the entropy, ideal solution (TOPSIS), improved TOPSIS and grey correlation analysis, were adopted to evaluate the manipulation comfort of tractor gear-shifting. A consistency check on the evaluation results of the five methods was conducted by using the concordance coefficient method of KENDALL. Furthermore, the combined weight vector of the compatible method set was calculated by maximizing the deviations. Through comparison, we found that the evaluation results of the combined methods were consistent with the subjective evaluation results. The method of combined evaluation can compensate for the insufficiency of single methods and overcome the inconsistency of the evaluation, and thus can produce more objective and accurate results. Our results can provide references for the quantitative research of manipulation comfort of agricultural machinery equipment.

A comfortable environment in railway passenger coaches can be regarded as a resource for social consumption during the transport process. Railway passenger comfort benefits (RPCBs) can be regarded as a special generalized cost. In this paper, we select a series of objective and subjective indexes to formulate a quantitative method of calculating the RPCB with considering ticket fares. This method includes three steps: make the initial data dimensionless, calculate the weight of each index, and finally calculate the RPCBs. The proposed method was validated with the data collected from two types of trains: G13 from Beijing South to Shanghai Hongqiao and T109 from Beijing to Shanghai. Also, questionnaire survey was conducted in both trains. After data processing, the results show that there is a linear relationship between the RPCB and ticket fare with a correlation coefficient of 0.9616.
