At present, although the domestic enterprise which have the ability to develop high speed and great capacity elevator manufacturers is a great quantity, but the elevator design, installation, debugging is still at the stage of experience, a large number of experimental not only cost of the human, material, but also increase cost of research, and high speed elevator that have already been put into use of are still many defects, such as poor structure stability, high quality of the car, the high cost of materials.
In the strain cloud we observe the four typical working conditions show that straightness which have no affect on frame reach design requirements, In the safety factor cloud we observe four typical working conditions which certify intensity and stability of the car frame, The analyses result show that this scheme not only improve the safety of the car frame but also reduce the cost of the car frame's materials.
