Ride comfort measurements in elevators

greenspun.com : LUSENET : Elevator Problem Discussion : One Thread

Can anyone help me with typical ride comfort measurements for elevators. I have recently carried out measurement on a new project using the EVA 625 from Physical Measurements Technologies. I filtered them using the 1999 ISO filter (ISO 8041) using the EVA 625 software. I then picked the max peak to peak values. I am getting horizontal values in the range of 10-20 milli-g, and vertical values in the range of 15 to 30 milli-g. The lift speeds range from 200 fpm to 500 fpm. What are the typical riding comfort values for those speeds? What would you consider a range of good riding comfort?

All of those lifts use sliding guide shoes (i.e., not roller guide shoes).

BEWARE no ammount of technical information takes account of the fact the rope anchorages are sprung to dampen the accelaration or stopping momentum, especially as you do not have roller shoes

best place to set the speed control is often in the car itself sometimes if it feels right it is right!!

Who really gives a stuff with all that "ride measurement " crap...the only ride quality that counts is the physical...i.e ride in the damn thing and if it dosent bounce jerk, sway etc then its ok....but i suppose we have to keep the bloody consultants in work somehow !!!!
