Embodiment Construction
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.
[0024] Such as figure 1 As shown, the curve in the figure is obtained by measuring the method of the present invention with an elevator quality analyzer (EVA625).
[0025] Based on the formula j=C 1 e Ct . (1)
[0026] according to figure 2 As shown, j represents the jerk, a represents the acceleration, and v represents the speed. First, determine an efficient and comfortable jerk curve. The accumulation of j is a, and the accumulation of a is v. Calculate j, a, and v through related formulas, and finally calculate through the formula Deduce the distance formula, calculate the formulas of [0, t7] interval j, a, v, given C1, C, T2, V, jmax, T, T3 can be calculated.
[0027] The velocity v adds up to the distance s. The Shannon sampling theorem points out that when the sampli...
