Hubbard 网页2015年1月22日 Dear Shri Ganesh, Belt modulus is the modulus of elasticity for belt, and its purpose is the same as modulus of elasticity for other materials. For materials, it is E = (Stress) / (Strain). This mathematically translates into required stress to create extension of length equal to original length i.e. strain = 1 which is called unit strain. 网页2010年1月6日 The elasticity characteristics of a conveyor belt are mostly expressed in permanent elongation and elastic elongation, measured during the Hysteresis test as described in EN ISO 9856. For some purposes, like the determination of the minimum troughing distance, the Elastic Modulus M of the belt is required. 网页2023年3月3日 a belt made from plastic. Neoprene, rubber, plastic and similar materials are prone to stretching, which throws off the timing, accuracy and repeatability of the process.
