Temperature variations in linear dimensions of elements of a broadband seismometer perceived by the latter as ground vibration

Mathematical Principles and Optimal Design Solutions to Compensation for the Pendulum Temperature Dilatation

“…That is why those rods on old tower clocks and so-called Vienna regulators 2 were manufactured from wood. Later, in the 19 th Century, with the discovery of the Invar alloy 3 , this compensation method was improved, but was never perfect enough. More complex design solutions had to be used for astronomical clocks, chronometers, best quality public clocks and even some wall clocks.…”

“…et al,in [2], explain the design, solid modelling and motion simulation of the remontoire mechanism only by which the influence of a pendulum thermal compensation for the clock accuracy can be significant and observable. K. V. Kislov investigates, in [3], the influence of temperature noise on the linear dimensions variation of new broadband seismometers, clarifies which elements of the device are the most sensitive to the ambient temperature variations and determines the level of noise generated by all the elements. In [4], Agatsuma K. Et al.…”
