5、 综述.7Rule of Thumb. 基本原则Relation WT / INT. WT和INT的关系Interpretation of Interval Waiting Time说明：间隔时间说明：间隔时间候梯时间候梯时间 The relation of interval INT and average waiting time WT has been examined for a number of different elevator groups. It has found out that the ratio WT/INT depends very much on the elev
6、ator group and on the arrival rate (as percentage of the maximum handling capacity).经过对比不同梯组的电梯间隔时间和平均候梯时间，我们发现：WT/INT系数很大程度上取决于梯组配置和到达率（与5分钟运载能力最大值相等） For assessing an elevator groups maximum performance, the usual relation of “WT = 60 % x INT” is not realistic. Better use “WT = 80 % x INT” or even
7、 “WT = INT”.要对电梯梯组的最大性能进行评估，惯常用的“WT=60%xINT”公式并不能反映真实情况，建议使用“WT=80%xINT”或“WT=INT”。.8Rule of Thumb. 基本原则How to Define the Car Load GQ? 确定电梯载重P = Ar x INTP = Passengers per car (car loaded with 80%)P = 每个轿厢的乘客数量（轿厢满载率80%）Ar = Arrival rate = arriving persons per secondAr = 到达率 = 每秒内到达的人数INT = Interval
8、considering waiting time WT = 80% of INT = rough estimationINT = 间隔时间按WT=80%xINT考虑 = 粗略估算Arrival Rate Ar (example): 到达率到达率Ar（举例说明）：（举例说明）：Population = 800, handling capacity = 14 %, arriving persons = 112 persons / 5 min人数=800，运载能力=14%，到达人数112人/5分钟Ar= 0.3733 persons / sec. Ar=0.37733人人/秒秒Interval IN
9、T (example): 间隔时间间隔时间INT（举例说明）：（举例说明）：Required waiting time WT = 24 sec 候梯时间要求WT=24秒Interval = (WT/80)x100 = 30 sec间隔时间间隔时间 = (WT/80)x100 = 30秒秒Car Load 电梯载重电梯载重P = Ar x INT = 0.3733 persons/sec x 30 sec. P = Ar x INT = 0.3733人/秒 x 30秒= 11.2 persons considering 80% car load = 11.2人，80%轿厢满载率= 14.0 pe

12、/每台电梯服务4个楼层）来计算电梯数量，应取两者的最大值。2.Estimated Speed 估算电梯速度估算电梯速度Elevator Speed to reach top/medium level travel time between 20-25 secV = HQ/t=20sec = 65/20 = 3.25 m/s expected speed 3m/s如要满足顶级或中档要求，电梯的行程时间应在20-25秒之间V=HQ/t=20秒=65/20=3.25米/秒，预期电梯速度为3米/秒。3.Estimated Car load 估算电梯载重估算电梯载重INT = (WT/80) x 100
13、 = (24/80)x100 = 30 secAr = (Population/100)*HC5 / 300 = (800/100)*14/300 = 0.37333 Persons/secP = Ar * INT = 0.3733 * 30 = 11.2 Persons (80% car load) 100% carload would be around 14.0 Persons) estimated car load (75 Kg/ person) = 1050 Kg would fit with a 1250 Kg Car Load DesignP=Ar*INT=0.3733*30=1
14、1.2人(轿厢满载率80%)，如按100%轿厢满载率，人数约为14人，按75公斤/人，则电梯载重=1050公斤，向上取整得电梯载重电梯载重1250公斤公斤。.10Schindler Traffic Standards.迅达交通流量标准.11Defined Traffic Situations 确定交通状况确定交通状况Schindler Traffic Standards. 迅达交通流量标准Traffic Situations (Criteria). 交通状况（标准）.12Schindler Traffic Standards. 迅达交通流量标准Star Rating (Criteria). 星
