To study the vibrations of a Multiparker lift lift model, use various models for the lifting mechanism. In order to increase the number of parking spaces in the center of the Romanian capital, it is intended to design a parking lot on several levels above the Dâmbovița river, which would include two elevators for lifting and lowering cars. One of the elevators works as a system of translating cam and roller translating follower and thus, due to transmitting the torque from the electric drive motor to the cam, respectively changing the travel direction at the end of the route, upon starting and stopping, vibrations may occur within the elevator. This system must be supported on a foundation in order to achieve anti-vibration isolation. There are several possibilities to achieve this anti-vibration isolation, among which one can mention the elastic suspensions mounted on springs, rubber mats or standardized elastic rubber elements

Papers present a new solution for achieving downforce to a brake disc, using a drive gear and ball screw-nut, which the construction adopted, allows moving ball-screw and making the necessary downforce for breaking. The stand includes downforce creating system required by deceleration, and is equipped with a plurality of sensors to determine the following parameters. Measurement of downforce-ring load cell, displacement in the running drive-pressure transducer, mechanism decoupling travel-differential inductive transducer, electrical motor and gear drive mechanism speed-speed transducer, and electric drive motor torque-lamellar load cell. These transducers allow the control of screw ball to realize the forces that are acting on the brake linings in order to control the speed of the vehicle. Using this construction, brake actuation can get higher quality reactions in brake systems.
