“…This is a standard approach in automobile dynamics modelling [7][8][9]. Proper vibration mitigation is of special concern in heavy earth-moving machinery and in mobile agricultural machinery [10,11]. To the authors' knowledge, there was not much locomotive engineer's seat suspension modelling reported, even this seems to be of major concern [12].…”

This paper shows that laboratory measurements can be used for the identification of structure and parameters of commercial seat vertical suspension system model. A commonly used single-degreeof-freedom suspension model does not suffice. The system model presented is based on Zener's structure and clearly describes the dynamic properties of a vertical seat suspension with an adjustable damper. The model introduced, augmented with seat cushion dynamic model, predicts the seat vertical vibration mitigation properties under field conditions with a reasonable accuracy. Optimisation of the adjustable damper setting is performed using a two-objective function optimisation technique. This enables us to optimise not only the exerted vertical vibration acceleration but also the seat relative vertical displacement (stroke). Optimisation was facilitated for the particular suspended seat without the requirement of further field measurements. In addition, a two-parameter optimisation was performed showing possible further improvement in both objectives at the manufacturer's discretion. This study could be representative of driver's seats equipped with vertical seat suspension system using an air-spring and an adjustable damper.

“…The self-power spectrum of field surface roughness of before and after planter working can be obtained by the theoretical analysis and software calculation [7][8]12], as shown in Figure 5. It can be seen from the graph that the power spectrum density curves had two peaks, and the frequency is the same.…”

“…The adaptability of the developed taped type planter for field surface roughness is one of main dynamic performance indexes of the planter [1][2]. Currently, the in-depth research on detection and analysis method of the surface roughness of pavement and farmland were ever carried out [3][4][5], but little research is focused on the effect of surface roughness on agricultural machinery working performance, and most researches are in the qualitative analysis level [6][7][8]. In order to explore the adaptability of the planter for surface roughness and to improve the operating performance of the working parts, the designed direct seeding machine is used as the research object to explore its working performance in the process of ditching, covering and compacting.…”

“…Besides, the pneumatic suspension systems, which were used in the suspension systems of the car, heavy truck, and rail vehicles to improve the ride dynamics and noise levels [22][23][24], were also investigated and applied for cab's isolation mounts and the driver's seat suspension to enhance the ride comfort as well as the driver's health and safety [25][26][27]. The research results showed that the vehicle ride comfort was obviously improved by using the pneumatic suspension systems.…”

This study proposes a dynamic model of the vibratory roller interacting with the off-road deformed terrain to analyze the lowfrequency performance of three different cab's isolation mounts under the different operating conditions. In order to evaluate the ride comfort of the vibratory roller with the different cab's isolation mounts, a three-dimensional nonlinear dynamic model is established. The power spectral density (PSD) and the weighted root mean square (RMS) of acceleration responses of the vertical driver's seat, cab's pitch, and roll vibrations are chosen as objective functions in the low-frequency range. Contrastive analysis of low-frequency vibration characteristics of the vibratory roller with the traditional rubber mounts, the hydraulic mounts, and the pneumatic mounts is carried out. Experimental investigations are also used to verify the accuracy of models. The research results show that the hydraulic mounts have an obvious effect on mitigating the cab vibration and improving the ride comfort in comparison with the traditional rubber mounts and the pneumatic mounts.
