Abstract
Under the condition of dynamic weighing, the support types of the column load cells can be divided into elastic support and oscillation support. The weighing system with oscillation support shows significant vibration characteristics, which affects the weighing accuracy and the fatigue life of the load sensor. In this paper, the dynamic characteristics of the oscillation supporting column load cell in low speed axle-group weigh-in-motion system are analysed. It is found that the restoring force of the oscillation support is approximately proportional to the oscillation angle and the applied vertical load. The dynamic equation of the oscillation support vibration of the column load cells established by means of d’Alembert principle. The numerical calculations of the dynamic response of the weighing system with oscillation support are carried out in the free state and dynamic weighing state respectively. The factors affecting the amplitude and recovery time of the support vibration are obtained. This study provides a reference for the analysis of the dynamic weighing accuracy.

Summary
Column load cell is an important component of the axle group dynamic truck scale. Under the condition of dynamic weighing, the support types of the column load sensors can be divided into elastic support and oscillation support. The weighing system with oscillation support shows significant vibration characteristics, which affects the weighing accuracy and the fatigue life of the load cells [1] [2]. The force analysis is carried out for the weighing process of the oscillation support column load cell. In the dynamic weighing system, the low speed axle group weigh-in-motion (LSWIM) system is used as the research object to ACTA IMEKO | www.imeko.org analyse the axle load conditions. The dynamic response of the weighing system is obtained through dynamic system model and simulation
