The Finished Product of Rubber Bearing Mechanical Performance Analysis in the Low Temperature

Abstract

In this paper, an experiment is carried out on compressive elastic modulus, shear modulus, silicon fat consistency and peel strength of synthetic rubber bearing and cold type natural rubber bearing produced in Shanghai Rubber Factory under low temperature condition. The experiment reveals the mechanical property of rubber bearing and change law of cooling temperature difference which offers reference and guidance for the selection of rubber bearing products under low temperature condition.

Calculation of Nonlinear Stiffness of Rubber Pad under Different Temperatures and Prepressures

“…e authors of [16][17][18] analyzed and studied the performance of rubber springs at low temperature; the results showed that low temperature has a significant effect on the properties of rubber. Österlöf et al [19][20][21] studied the relationship between the rubber model and temperature.…”

Study of Vertical Characteristics with Changes in Prepressure of Rubber Pad Used by High‐Speed EMU

“…Select 45 kN as the conversion standard, and calculate λ N•45 when the prepressure is 57 kN, 65 kN, 75 kN, and 85 kN according to the theoretical formula (18); use formula (19) to calculate the dynamic parameters and compare with the test value, as shown in Figure 12. is method is named the theoretical DFCC prediction method (Method 1).…”

“…In order to highlight the research focus and more clearly reveal the change rule of performance parameters with the prepressure, select a specific frequency and amplitude for comparison; only consider the relative change of performance parameters when the prepressure changes. According to the assumptions that the parameters of dynamic-static parameters increase in the same proportion with the change of prepressure, and according to formula (18), the following formula can be obtained:…”

“…ere are many factors that affect the performance of rubber springs, such as frequency, dynamic amplitude, basic size, material, temperature, and prepressure, but there are relatively few studies on temperature and prepressure. Li et al [17][18][19][20][21][22] studied the performance of rubber components in different temperature states and have proven that temperature has an influence on the performance of rubber. Especially in the low-temperature state, the rubber property is obviously changed, which is caused by low-temperature crystallization.…”
