(2) The steady running performance of the lever-type car is less sensitive to damper wear than the wedge-type car.
Dynamic performance characteristics of the lever-type damper and the wedge-type damper are compared in terms of the nonlinear critical speed, riding index, and curve negotiation.
The reinstatement, or relapse, test is conducted by again presenting the drug CS, but not the drug, following performance of the recently extinguished lever press response (Shalev et al., 2002; Shaham & Miczek, 2003; Epstein et al., 2006; McNally, 2014).
Finally, the dynamic performance of a lever-type car is analysed and compared with a wedge-type car to verify its feasibility.
To overcome defects caused by the complex structure and unstable damping performance of the wedge-type damper, a new lever-type friction damper has been developed for use in freight bogies; the design allows the advantages of traditional three-piece bogies to be retained.
In Experiment 1, lever-press autoshaping CRs developed in all rats, and the tendency of a rat to drink an ethanol concentration was predictive of the performance of lever-press autoshaping CRs.
Through theory analysis, strength analysis of the lever, and the comparison of the dynamic performance of vehicles equipped with the two types of dampers, conclusions are as follows: (1) Compared with a traditional wedge-type damper, the lever-type damper can significantly simplify the structure of the bolster, and improve its reliability.
The pulling of the lever?
The influence of the lever's compliance is significant.
The lever's compliance can be modeled by cascading a linear spring at the end of the lever.
