Abstract
The invention provides a test bench used for detecting the performance of a front shock damper of a motorcycle. According to the test bench, a synchronous motor (1) is employed as an exciting power supply, the motor (1) is installed above a test bench crossbeam (2), a straight rod (4) is driven to move through a transmission system (3), the straight rod (4) passes through the crossbeam (2), a force transducer (5) is fixed on the straight rod (4), a displacement sensor (6) is connected with the front shock damper (7), and a control stand is used for controlling an installing angle of the front shock damper (7). The test bench employs a mechanical exciting structure, construction is simple, control is easy, through adjusting rotation speed of the motor, data of the shock damper in extremely low speed movement can be obtained, and the accuracy of a test result is facilitated.
Description
Technical field
The present invention relates to be used to test the equipment of vibroshock performance, be specifically related to a kind of testing table that front damper is tested.
Background technology
In recent years, along with developing rapidly of China's motorcycle industry, whether, safety comfortable for motorcycle riding more and more become the focus that people pay close attention to.Vibroshock as one of critical component of motorcycle; Its effect is exactly in order to relax motorcycle under steam; Receive shock and vibration because of road is uneven, guarantee the ride comfort and the security of driving, so its performance directly has influence on the quality and the performance of car load.
The vibroshock testing table is the testing equipment that detects to the shock-absorbing capacity in the vehicle shock absorber operational process, and test findings can directly be checked out the good ring of vibroshock performance, is the indispensable test detecting equipment of support vehicles safe reliability.In test, reply vibroshock one end applies standard simple harmonic motion excitation, and that detects vibroshock on this basis shows merit characteristic, velocity characteristic etc.At present the energisation mode of vibroshock testing table has two kinds of hydraulic exciting and mechanical excitings, and exciting is to force vibroshock to be in certain duty.Hydraulic exciting formula vibroshock testing table servo apply hydraulic pressure oil cylinder is as excitation power source, and the shortcoming that this testing table exists is: noise is big, leakage of oil can take place, and the difficulty of control system relative complex, control is big.And mechanical excitation type vibroshock testing table is to be power source with the motor, and control is simple, through regulating motor speed with regard to the scalable excited frequency.
Summary of the invention
The purpose of this invention is to provide a kind of mechanical type front damper property test platform, simple in structure, convenient control can make vibroshock under extremely low speed, move.
For realizing the foregoing invention purpose, the present invention adopts following technical scheme:
The front damper property test platform adopts motor as excitation power source, and said motor is installed in the top of testing table crossbeam; And be connected with straight-bar through kinematic train; Said straight-bar vertically passes crossbeam, and force transducer is fixed on the said straight-bar, and displacement transducer is connected with front damper; Control desk is positioned at the place ahead of testing table, is used to control the setting angle of said front damper.
Testing table of the present invention adopts mechanical excitation structure, is easy to control; Utilize motor as power source,, vibroshock is promoted with utmost point low speed (0.05m/s), be beneficial to the accuracy of test through regulating the transmission of rotating speed of motor and (3).
Description of drawings
Fig. 1 is the structural representation of testing table of the present invention.
Fig. 2 is the right flank synoptic diagram of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done explanation in further detail.
As shown in the figure, testing table of the present invention comprises base, crossbeam 2, column etc., and motor 1 is positioned at the top of crossbeam 2, and straight-bar 4 vertically passes crossbeam 2, and is connected with motor 1 through kinematic train 3.Kinematic train 3 is made up of pinion wheel, gear wheel and feed belt.
During test, the angle of front damper by actual entrucking is installed on the testing table, by the angle of control desk 8 control vibroshocks 7.Drive straight-bar 4 by motor 1 then, and slowly rise along the axis direction of straight-bar 4, upwards spur the end tube of vibroshock 7, make 7 end of vibroshock tube move (from the free travel state to the minimum stroke state) on slowly, the minimum speed that moves can reach 0.005m/s.Through force transducer 5 and displacement transducer 6 variation and the change in displacement that this lifts the power of process is transferred in the computer, test images described out by trace routine.
Testing table of the present invention can be gathered vibration wave through vibroshock 7 is come off automatically, carries out the test of impulsive force; Vibroshock 7 is at the uniform velocity moved up and down, and testing friction power obtains the damping characteristic of vibroshock 7 under utmost point low-speed motion.Be loaded on the car in the practical working situation of road driving through the simulation front damper, can estimate the performance that vibroshock is used to satisfy the human comfort requirement.
Claims (2)
1. front damper property test platform; Adopt synchronous motor (1) as excitation power source; It is characterized in that: said motor (1) is installed in the top of crossbeam (2), and is connected with straight-bar (4) through kinematic train (3), and said straight-bar (4) vertically passes crossbeam (2); Force transducer (5) is fixed on the said straight-bar (4); Displacement transducer (6) is connected with front damper (7), and control desk (8) is positioned at the place ahead of testing table, is used to control the setting angle of said front damper (7).
