Displacement Measurement Novel Method Non-contact in Uniaxial Restrained and Adjusted Temperature-stress Testing Machine

摘要：

In view of the characteristic and the existence question of the uniaxial unrestrained temperature-stress testing machine, this paper adopts non-contact displacement measuring technique that suits this testing machine. This technique makes use of non-contact laser sensors and two sets of measurement subsystems that are symmetrical distribution. This method has overcome existence measuring error that comes from contact point of the conventional contact type measuring technique, remarkably increased the measuring precision.
