Abstract

PURPOSE: To enable continuous and automatic measurements of bending coefficient, Young's modulus and spring limit value accurately, by providing strain gauges on both surfaces of bimetal, applying load to the bimetal, and measuring and recording the amount of strain.
CONSTITUTION: A bimetal test piece 1 is secured to a support tool 6, and first and second strain gauges 4, 5 are attached to the low and high expansion sides 2, 3 of the test piece 1. Under no load state, the test piece 1 is heated and bent, and strain amounts ε1, ε2 at temperatures T1, T2 are measured to obtain the bending coefficient K=(ε2-ε1)/(T2-T1)continuously. Also, expressing the strain amount of the test piece 1 under no load state by εa and the strain amount when a load is applied to a standard point 14 at the free end of the test piece 1 byεb, the Young's modulus E of the test piece 1 may be directly obtained from the strain difference at temperature T, Δε=εb-εa. Besides, taking the strain amount under no load at temperature T as εa and the strain amount after applying load and removing it as εr, by changing the load and measuring the strain amounts βa, εr, the spring limit value Kb may be obtained.
