Abstract
Description
支持部分101a、101bの傾斜、ひいてはプレートの湾曲が制御されるようにフレーム109の湾曲を制御することを介して第2のフレーム要素103a、103bにトルクを加えることができる。図3aに示すアセンブリでは、フレームが実質的に平らでパネル1と平行になるように正味の力が加えられる。図3cおよび3dに示すアセンブリでは、支持部分101a、101bから離れる正味の力がフレーム109に加えられ、プレート2のタッチ面から見たときにわずかに凹状になる。結果として、トルクが第2のフレーム要素103a、103bに提供され、それによってプレート2の縁部または周囲に沿って支持部分101a、101bが傾斜する。したがって、第1のフレーム要素109の曲率を制御すると、プレートの曲率を制御することができる。プレート2は、プレート2のタッチ面から見て凹状になっていてもよい。
F(x)=-a+cx2
本実施形態例では、図11cのタッチ面の長さ1900mmの断面とx軸との間の最大距離aは2.0mmである。したがって、タッチ面20に対する理想的な放物曲線は、以下の通りである。
F(x)=5.5*l0-6*x2-2.0
ここで、F(x)は位置xにおけるx軸とタッチ面との間の距離であり、x軸が縁部と交差する場所では、F(x)は縁部の中点でゼロである。
z(x,y)=-a+b*x2+c*x2y2+d*y2
ここでzは、x軸およびy軸で定義される面とタッチ面との間の距離であり、xとyはガラス面内の座標である。
z(x,y)=-2+5.56e-06*x2-4.74e-11*x2y2+1.7e-05*y2
z(x,y)=-2.5+5.56e-06*x2-2.37e-11*x2*y2+1.28e-05*y2
凸bは、図18aに示されている。放物線誤差は図18bに示されている。
