这是一个老话题。但是,我使用去年撰写的杂志文章中的公式编写了程序。设计伺服液压系统时应使用蓄能器,因为它可以
1.减小泵的尺寸。存钱。
2.减少压力变化。提高性能。
首先必须知道运动曲线。
然后,必须使用运动曲线来计算流量,需要使用运动曲线和气缸活塞的面积来计算流量。
然后计算储油器中换油量。需要进行模拟以计算从泵添加的油与阀使用的油之间的差。
储油器的尺寸应为油量变化的许多倍,因此压力变化不会超过10%,并且储油器不会用完油。
程序可能会计算不可用的阀门,泵和蓄能器的值。用户可以输入下一个更大的可用大小,程序将使用用户的参数值重新计算。
计算机将尝试不同的组合以寻找最佳解决方案。
This is an old topic. However, I have written a program using the formulas from the magazine articles I have written in the last year. An accumulator should be used when designing a servo hydraulic system because it can
1. Reduce the size of the pump. Save money.
2. Reduce pressure changes. Increase performance.
First the motion profile must be known.
Then the flow must be calculated using the motion profile needs to be calculated using the motion profile and the areas of the cylinder piston.
Then the volume of oil change in the accumulator is calculated. A simulation is needed to calculate the difference between the oil being added from the pump and the oil used by the valve.
The accumulator should be sized many times the change in oil volume, so the pressure does not change by more than 10% and the accumulator is does not run out of oil.
Chances are the program will compute values for the valve, pump and accumulator that are not available. The user can enter the next larger available size and the program will recalculate using the user’s parameter values.
The computer will try different combinations in a search for the best solution.
