摘要：
The force of a lifting cylinder is the main factor of the alternating stress of scissors arms in a scissors aerial work platform, which seriously affects the fatigue life of structures. Aiming at this problem, the installation position parameters that affect the force of the lifting cylinder was simulated and optimised. First, the mechanical model of the lifting system was established based on the principle of virtual work, and the position parameters that affect the force of lifting cylinder were determined. Then, the advanced modeling environment for performing simulation of engineering systems (AMESim) simulation model was used to simulate the lifting process of the lifting system, and the reliability of the simulation model was verified by the pressure test of the hydraulic system. Finally, based on the simulation model, the design of experiment method was used to optimise the installation position of the lifting cylinder in the design and development environment of AMESim, and the optimisation effect was verified through the test on a real vehicle. The result shows that the peak load of the lifting cylinder is reduced by ∼12%, and the average of the steady-state value decreases by ∼20% after the installation position is optimised.

摘要：
To improve the energy efficiency of hydrostatic vehicles, this work studies the energy regeneration systems (ERSs) for a battery-powered hydrostatic vehicle (BHV). First, the structure of a BHV with ERSs is presented, and the working principle and performance of the main components are analysed. Three energy regeneration modes (ERMs) are proposed, namely, the battery mode, the battery-accumulator mode and the accumulator mode. The energy flow of vehicle acceleration and braking in the three ERMs are analysed, and the corresponding control strategies are designed. The power output and energy consumption of key system components, the system energy flow, the system component energy consumption, and the parameters and energy consumption of the hydrostatic components are comprehensively compared and analysed. The comparative analysis results show that under the battery mode, the whole system and the hydrostatic system have the highest energy efficiency and the battery-power hydrostatic vehicle can achieve a better energy conservation effect.

摘要：
Oil pump models with different gear tooth shapes were established and the internal flow field simulation were conducted by utilizing Pumplinx. Then the characteristics of steady state flux and flow pulsation were analyzed. The research shows that: compared with straight gear pumps, the flow pulsation of other toothed gear pumps is much lower, although they have lower flow at low and medium speed. Especially the flow pulsation of dislocation gear pumps is much lower than straight gear pumps. It decreased by 27% at 1100 rpm and 35% at 2700 rpm, compared with straight gear pumps. Finally the straight gear pump flow is tested experimentally, and the experimental results match the simulation very well. This proves that the internal flow field models are correct and useful in technically supporting the oil pump development.
