The vibration frequency should be set to obtain large dynamic stress with low energy consumption, and the resonance frequency should be used to handle time dependent vibration. However, there may be one or more resonance peaks in large components,XinjiMobile boarding bridge, which slowly increases the speed of the excitation motor from 0, a large acceleration was obtained at 5366r/min, so 5366r/min was determined as the aging frequency.

Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.

Xinji.Check the oil level of the gearbox and make up for new oil if necessary

The arrangement of vibration points should be based on the vibration aging process standard GB/T25712-20. The vibration aging exciter should be placed at a position with high rigidity and amplitude of the workpiece, and its rotating axis should be parallel to the plane where the effective zone of the vibration mode is located. The exciter should be fixed at the end angle or edge of the workpiece with high rigidity so that small energy can be used to excite the component with large amplitude. Based on the structural shape of the foundation, we set the vibration points on the protruding plates on each side of the workpiece.

The selection of vibration pickup points refers to the placement point of the sensor, which is used to measure the vibration amplitude of the workpiece. According to GB/T25712-2010,XinjiTilting lifting platform, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude, and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component,XinjiAluminum alloy hydraulic lifting platform, the vibration pickup point is set in a thick area in the middle of the component.

Quality department.The vibration frequency should be set to obtain large dynamic stress with low energy consumption, and the resonance frequency should be used to handle time dependent vibration. However, there may be one or more resonance peaks in large components, and using resonance peaks with higher peaks and lower frequencies for aging can achieve optimal results. The resonance frequency needs to be determined by trial vibration, which slowly increases the speed of the excitation motor from 0, and determines the relationship curve between the amplitude of the workpiece and the motor speed to determine the resonance point of the workpiece. According to the scanning curve, a large acceleration was obtained at 5366r/min, so 5366r/min was determined as the aging frequency.

The curved arm lifting platform adopts a curved arm working arm, and the scope and space of operation are not affected.

According to GB/T25712-2010, when one of the following situations occurs in the curve related to the aging frequency, it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises, then falls, and then flattens; The resonance frequency of the a-n curve after vibration is lower than that before vibration; The bandwidth of the a-n curve after vibration narrows compared to before vibration; The resonance peak of the a-n curve after vibration exhibits fission phenomenon; The curve flattens out after descent.

According to calculations, when the support points of the beam type components are located along the length of 1/9L on both sides, the vibration resistance is relatively small, making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component, and the structure is complex. Therefore, two support points should be taken on each side for time treatment.

Design brand.Low failure rate: Due to the use of advanced hydraulic systems and good methods the failure rate of elevator operation can be minimized. Low power consumption: When the hydraulic elevator descends, it is driven by the pressure generated by its own weight, which greatly saves energy.

Organize, remove rust, and repaint structural components such as suspension cages and guide rails for corrosion, and reinforce load-bearing members with severe corrosion

Emergency stop: Press the emergency button switch to raise or lower the machine.

Xinji.The design of support points for selecting process parameters is to avoid energy consumption and noise generation due to collision between components and supports during vibration. The supports should be arranged near the nodal line, two point supports can be used; When the aspect ratio is close to 1, it is advisable to use or 4-point support.

The lifting foundation of the platform is a large structural component made of alloy steel plates with different thicknesses that are welded together. The welding amount is large, the structural shape is complex, and residual stress is inevitably generated during the manufacturing process. In order to prevent deformation of the components due to changes in residual stress during use it is necessary to perform stress relief treatment on the completed components.

According to GB/T25712-2010, when one of the following situations occurs in the curve related to the aging frequency, it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises, then falls, and then flattens; The resonance frequency of the a-n curve after vibration is lower than that before vibration; The bandwidth of the a-n curve after vibration narrows compared to before vibration; The resonance peak of the a-n curve after vibration exhibits fission phenomenon; The curve flattens out after descent.
