Mechanical energy spring?

The results of vacuum exhaustion test of stainless steel compression spring cycle show that:


1. Medium-sized industrial spring reel

Can be the cause of a series of steel springs breakage. According to the combination of and the combination of rigid-flexible coupling dynamics considering the flexibility of a series of steel springs are established... The development of Italian intercity train type air spring, the development of Italian intercity train type air spring, introduced the main technical parameter requirements, structural design and finite element analysis of Italian intercity train type air spring, and carried out the experimental verification of air spring type, after the product loading and application test, the results show that the functions of the air spring meet the technical requirements. The rules of motion of the spring oscillator in the lubrication horizontal plane, the motion rules of the spring oscillator in the lubrication horizontal plane, and the model of the movement in the lubricating horizontal plane has a motion differential in the spring oscillator of nonlinear double degrees of freedom movement

2. Jiangyin spring

The void seal design of the spring points out the change rules of radial stiffness at different radial force angles and eccentricity distances. The stiffness of Archimedes' spiral is theoretically analyzed, the axial stiffness formula is obtained, and the stiffness stress coefficient is proposed to evaluate the spring function. After Z, the theory is applied to finite element imitation, under the same axial stiffness, compared with the five vortex profiles, the Z maximum stress of Archimedes' spiral is small, which is suitable for long life... The application of spring contact finger in handcart circuit breaker, the application of spring contact finger in handcart circuit breaker, and the excessive tightening force of the plum contact hoop of handcart circuit breaker are easy to show climbing during the handcart pushing process. The causes of the climbing problem were analyzed, and combined with the advantages of spring contact points and good conductive function, the prototype was trial-produced and tested


3. Air spring shock absorber

The scale of the connecting plate is optimized, and the mathematical model of the spring actuation arrangement after optimization is established, which is carried out and simulated separately. The simulation results show that the arranged output characteristics and the load special function of the circuit breaker can be excellently matched, and the optimized contact spring pressure is... In order to improve the wear-resistant function of the steel surface of spring, the microscopic arrangement and conflict function of the steel nitriding layer for spring, the nitriding treatment at different times and temperatures is carried out, and the microscopic arrangement, hardness and conflict function are experimentally tested. The results show that the nitriding layer forms an uncorroded bright compound layer, and the dispersed layer turns black due to the erosion effect.
