包络曲线
Examples
- Application of enveloping curve of circular arcs in design of roots rotor profile
圆弧包络线在罗茨转子型线设计中的应用 - With the new - simple method , the equation of circle - arc - enveloping curve are deduced . also the relationship between the arc radius , the radius of center distribution and the distance of centers is given to avoid undercutting
文中采用新方法推导出了圆弧包络线转子型线方程，还给出了避免出现根切现象的圆弧半径、圆弧圆心分布圆半径以及中心距三者之间的关系。 - With the experiment part , the errors of sk - 21 nc machine tool have been measured , and a serial of data is gotten which lead to the error discrimination . ( 3 ) based on the kinematical theory of mbs , the calculation methods for the ideal center envelop curve of grinding wheel on cam grinding , the practical cutter track , inverse contour of cam , ideal nc instructions , precision nc instructions , the inner / outer normal and the fitting criterion of curve have been all discussed in detail in this paper
( 3 )通过精密加工的约束条件方程,探讨理想刀具路线、逆变数控指令与实际刀具轨迹之间的映射关系,解决误差补偿技术提高加工精度的核心问题? ?当要求数控磨床的砂轮中心准确到达给定的理想点时,精密数控指令值究竟该是多少,如何能够通过计算,获得这样的数控指令值,给出经修正的数控指令计算方法。 - Comparison including the cracking , yielding and ultimate loads of the beam , load - displacement curve , envelop curve , the ductility and energy - dissipation capacity were made between the response of the specimens before and after strengthening . test results indicated that the yielding loads of the specimens after strengthening were improved from 12 . 3 percent to 17 . 2 percent and the improvement of specimens rehabilitated by jacketing was higher than that of the bonding steel plates one
加固后试件破坏同样发生在梁端，屈服荷载比加固前提高12 . 3 17 . 2 ，与粘钢加固相比，加大截面法加固的试件承载力提高幅度较大；加固后试件的延性和耗能性能比加固前有很大的改善，其中以粘钢加固的试件提高最为明显。
