The Impact

The dynamic characteristics analysis about the jet pipe electro-hydraulic servo valve based on experience and mathematical derivation was difficult and not so precise. So we have analysed the armature feedback components, torque motor and jet pipe receiver in electrohydraulic servo valve by sophisticated finite element analysis tools respectively and have got physical meaning data on these parts. Then the data were fitted by Matlab and the mathematical relationships among them were calculated. We have done the dynamic multi-physical fields’ Simulink co-simulation using above mathematical relationship, and have got the input-output relationship of the overall valve, the frequency response and step response. This work can show the actual working condition accurately. At the same time, we have considered the materials and the impact of the critical design dimensions in the finite element analysis process. It provides some new ideas to the overall design of jet pipe electro-hydraulic servo valve.

Simulation Results

This study analyzes the maximum load on the shaft construction with a diameter of 12 mm and a length of 581 mm. The shaft is designed as a shaft for cutting meat with a capacity of 5 kg. The analysis was performed using the finite element analysis method included in the Autodesk software. According to mathematical calculations, the shaft is considered safe because the value of the admissible tension τa = 7.380 kg / mm2 is greater than the maximum tension τp 5.62 kg / mm2. Based on the simulation results of the test, the shaft experiences a maximum off-stress of 61.89 MPa, a maximum displacement of 0.07715 mm, , and a safety factor of 3.34 µl so that the shaft is classified as safe for use with a Load capacity of 5 Kg

Simulation Results

Three different kinds of carcass A, B and C for aircraft tires were presented in the article, which is based on the different length of rolling up for carcass cord across the bead ring. And then they were simulated by applying finite element analysis method when aircraft tire was landing in an instant. The simulation results indicated that, the carcass structure of rolling up from the side of bead extending to the other bead (A type) has the minimum deformation, which can reduce the outward of bulge for the side wall and effectively resolve the failure problem for rubber in the sidewall of tire , what’s more , it can prolong the life of aircraft tire to a certain degree and provide good braking performance.
