Hydraulic dampers are mainly used to maintain high-speed trains in a stable state when running at high speed. In this paper, an equivalent method for the lifetime of dampers is proposed to establish the relationship between the long-term loading test and the mileage in service condition. The performance degradation of the damper at different temperatures is calculated using the long-term loading test carried out under the corresponding temperature conditions. Arrhenius model is applied to convert the degradation under different temperatures, and the sensitive parameter is selected for the conversion of the damper’s performance degradation under different temperatures. An energy method is proposed to solve the problem of the damper lifetime under different loads, so as to achieve the equivalent of the damper between the long-term load test and the mileage in service condition. Finally, taking the anti-yaw damper of a certain type of high-speed train in China as the research object, the lifetime equivalent method proposed in this paper is applied and the result showed that the anti-yaw damper had remaining service life after 2.4 million kilometers of service.

The aim of this study is to identify the issues that arise when measuring a strain signal in order to characterise fatigue failure. In traditional methods, acquisition of a strain signal is constrained due to the presence of errors, time-consuming process and associated high cost. In this study, a new method for generating strain signals based on computer simulation was proposed. A strain gauge was positioned near the citical area pertaining to an automotive coil spring driven on road surfaces in order to measure strain signals. The strain signals were utilised for the inputs in the simulation. For validation purposes, the actual and simulated strain signals were examined by performing fatigue tests. The actual and simulated urban strain signals, respectively, required 412 and 415 reversals of blocks. For the rural road, the fatigue life was 137 and 139 reversals of blocks, respectively, for the actual and simulated strain signals. These indicated that simulated strain signals were accurately generated, providing a minimum fatigue life deviation, which was lower than 1.5 %. By developing the strain signals of a component through simulation, its integrity and fatigue failure can adequately be determined, thereby, saving the cost associated with operation and maintenance. Thus, the simulation is expected to assist the automotive industries involved with strain signal acquisition.

“…With the testing strain signals of different test conditions and local strain-life method, fatigue life is predicted for the damper spring tower. 19 Taking an increased mass into account, the durability and life cycles of suspension for a small car are assessed. Using a rain flow counting cycle method and Palmgren–Miner rule, the fatigue life cycles are predicted based on identified cumulative damages for the suspension.…”

This paper investigates the dynamic characteristics and fatigue robust optimization of heavy-duty tractor. First, this paper presents a vehicle model with sub-structure method. Based on the theory of base motion, the structure dynamic characteristics are analyzed. Second, the accuracy of the method is verified by comparing the experimental results with the simulation results. Also, the dynamic response and the transfer function of vehicle are obtained using the above methods. Combined with the experimental data, the methods of random multiple frequency components and multi-axial fatigue life are adopted to analyze the fatigue damage of the heavy-duty tractor under different road conditions. Finally, the Design for Six Sigma is used to optimize the vehicle’s structure. The results show that by using the proposed method, the dynamic characteristics of the vehicle can be analyzed accurately and effectively, robustness of the vehicle can be improved, and mass of the vehicle can be reduced.
