Abstract
The invention discloses a method and a machine for making force, in particular to a synthesis method of constant-direction inertia resultant force and a shimmy type propeller, and the constant-direction inertia resultant force can be used as driving force of a carrier (vehicle, ship and aircraft) of a force-making machine and can also be used as the force used for operations (road rolling, bulldozing and farming) of engineering machinery and agricultural machinery. A creatively designed biaxial shimmy mechanism is formed by transforming an existing biaxial inertial vibration exciter. Four groups of the biaxial shimmy mechanisms are utilized for carrying out mechanical superposition, thereby eliminating negative half waves of a non-equivalent vibration wave curve of absolute waves of wave peaks of positive and negative half waves and further obtaining the constant-direction inertia resultant force of high frequency micro-fluctuations. Compared with the aerodynamics propulsion or friction force propulsion (a driving wheel), the shimmy type propeller can bring new functions (such as a land-air amphibious vehicle and a road-rolling and bulldozing dual-purpose machine) or performances (such as energy conservation) for transportation machinery, the engineering machinery and the agricultural machinery. The shimmy type propeller has the preliminary design of the no-fluctuation inertia resultant force.
Description
Technical field
The present invention relates to a kind of method and machine of the power of manufacturing, be used to make the driving force of power machine carrier (car, ship, aircraft), also be used for engineering machinery and agricultural mechanical operation (pressing road, soil-shifting, farming) firmly.
Technical background
The machine of manufacturing power is called for short force generator.The inventor broke through the constraint of Newtonian mechanics action-reaction law, is foundation with mechanical energy conversion conservation law, developed force generator since 2000.Force generator has been applied for patent of invention twice, and the patent No. is ZL00114417.0 for the first time, and denomination of invention is force generator with adjustable eccentricity and application thereof; Number of patent application is 03145174.8 for the second time, and denomination of invention is that wall force generator and application thereof are pressed in variable eccentric rotary dual-wheel rotor alternating single-wheel in the cylinder.The novelty deficiency of the patent application relatively for the first time of patent application is for the second time rejected application by Patent Office of the People's Republic of China.The system power method of this twice patent application all adopts rotational vibrations formula system force mechanisms.The Inst. of Mechanics, CAS's examination once of force generator patent application specification thinks that thinking is feasible.Preliminary test has been done in patent application, does not achieve success as yet, but has found the key technology of achieving success, is still continuing to improve design at present.When key technology is achieved success in the searching test, the inventor studies " theoretical mechanics " in great detail, and (theoretical mechanics teaching and research room of Northwestern Polytechnical University compiles, People's Education Publishing House's in July, 1961 front page, the first volume, 159～163 pages) about the speed and the acceleration formula of each point in the rotary rigid body, the cosine swing equation innovative design of using this book to provide does not have the dual-axis swing oscillatory type system force mechanisms of report as yet, and twin shaft cosine is swung oscillatory type system force mechanisms carry out mechanical analysis (seeing aftermentioned for details), thereby reach a conclusion, adopt swing oscillatory type system force mechanisms more clear aspect theoretical than employing rotational vibrations formula system force mechanisms, be more readily understood, more make the power advantage.The design key of swing oscillatory type system force mechanisms is with the minimum profile size rotating mechanism to be converted into the cosine swing mechanism.
At the force generator research process, many scientists both represented certainly theory, but suspection can promote object of which movement, because the present invention is difficult to make explanations with newton's action-reaction law.Have only and invent the attitude that just can disarm suspicion of achieving success.Vibration advances and is actually rigid body swing kinetic energy to the conversion of carrier (vehicle) straight line kinetic energy, meets mechanical energy conversion conservation law.It is artificial trying hard to recommend into that vibration advances, and is different from natural force (frictional force, Air Force) and promotes, so can't explain with newton's action-reaction law.Artificial power is the people for creating, and natural force is that nature itself exists.Up to now, people seldom study artificial power.Past is confined to solve the equilibrium problem (as the internal combustion engine moving balance) of mechanical motion mechanism to the research of inertial force, and never the people goes to study the problem that obtains the ripple disable inertia resultant force.The past people just study natural force dynamics, and artificial power dynamics is nobody's business.
The objective of the invention is to seek to promote object of which movement and obtain historical breakthrough, in the physical science field, applying mechanical energy conversion conservation law developing rigid body swing kinetic energy is to the research of carrier (as vehicle) straight line kinetic energy conversion; Next is to seek transportation machinery, farm machinery and engineering machinery (as automobile, helicopter, aircraft, submarine, tractor, road roller etc.) to adopt and to obtain new performance (as energy-conservation) or function (as air-ground amphibious no wing driving, drive the very fast no wing jet airplane of air-ground amphibious tractor or agricultural transportation vehicle, air-ground amphibious tank armor car and military low latitude with pressure road soil-shifting double-purpose machine, the remotely pilotless of plastics manufacturing) behind the shimmy formula propulsion device.
Economic benefit that the present invention can bring and social benefit still can not be affirmed at present, because the shimmy formula propulsion device of the present invention advances with aerodynamics, frictional force advances the energy-saving effect of comparing to remain to be deepened research.The shimmy formula propulsion device development tuning system power technology of still needing makes shimmy formula propulsion device have than other propulsion device and more manys advantage.The energy loss of shimmy formula propulsion device conversion process of energy is that as long as reduce friction factor, energy loss just can reduce owing to frictional force between the mechanical motion part causes.Reduce friction factor and can adopt nano lubricating oil, nanometer anti-friction bearing material and high-grade machinery part surface degree of finish.Also there is very big waste gas kinetic energy rejection in the energy loss of aerodynamics promotion energy transfer process frictional force causes between the mechanical motion part.It is drive wheels propel that frictional force advances, and the energy loss of its conversion process of energy frictional force causes between the mechanical motion part, also exists because deadweight causes the rolling resistance loss.Bulldozer for example, thrust is relevant with the bulldozer deadweight, and making bulldozer with plastics can be energy-conservation, but loses thrust simultaneously.Bulldozer, road roller with shimmy propelling can be used the plastics manufacturing, reduce the energy loss that the machine own wt causes.Analyze theoretically, shimmy propelling advances with aerodynamics, frictional force advances and compares the function that the most tangible advantage is change mechanical motion propelling.The aerodynamics aircraft produces lift needs very big wing of boundary dimension or rotor (helicopter), so existing aircraft can not travel on highway and rely on the airdrome to rise and fall.The air-ground amphibious Wing-free airplane of shimmy propelling has the advantage of automobile and the advantage of helicopter.Adopt remotely pilotless to drive the air-ground amphibious car that vibration advances and be used for agricultural, can realize that the paddy field do not have the rut farming, can be suspended in paddy rice or other crops surfaces spray fertilizer, agricultural chemicals or weed killer, can solve mountain area terrace agriculture mechanization problem.Have wing aircraft with the flying speed increase flight resistance of wing to be increased rapidly, this is the obstacle of very fast military aircraft design.The lifting of system power combines with jet or rocket horizontal sliding, and this is the optimum scheme of the very fast Wing-free airplane in military low latitude.Low-latitude flying can be escaped search lighting.Make transportation machinery, farm machinery and engineering machinery with plastics, make its weight saving, reduce rolling resistance and reach energy-saving effect.The swing type propulsion device adopts tuning system power technology, can design and press road soil-shifting double-purpose machine, makes the engineering machinery one-machine-multi-function.
Summary of the invention
The present invention realizes like this, twin shaft inertia vibration generator rotary type vibrating mechanism is changed into dual-axis swing vibrating mechanism (the swing vibrating mechanism is called for short shimmy mechanism), and promptly the vibrating mechanism that positive and negative half-wave absolute value is equated changes the vibrating mechanism that positive and negative half-wave absolute value does not wait into.Shimmy mechanism tangentially makes a concerted effort still to change in the direction of Y direction component, but normal direction (centrifugal) makes a concerted effort not change in the direction of Y direction component, and normal direction makes a concerted effort to make a concerted effort at the crest absolute value of Y direction component greater than tangential at the crest absolute value of Y direction component.In order to obtain the constant inertia resultant force of direction, must adopt the mechanics principle of superposition to make the inertia resultant force superposition of positive negative direction, eliminate a direction and inertia resultant force occurs.Solution is the vibration wave waveform dislocation that produces with two groups of shimmy mechanisms, and the dislocation of vibration wave waveform is determined (the crankshaft pin position angle of similar each cylinder of multi-cylinder engine is arranged) by the crankshaft pin that produces swing in the circumferential position angle.Then to adopt the wave-wave shape dislocation of shaking of four groups of shimmy mechanisms of twin shaft in order to reduce the shake fluctuation (promptly obtain flat preferably ripple effect) of ripple curve of the constant inertia resultant force of direction.Want to reach flat ripple, can design the change pendulum radius and reach.Synthetic method about the ripple disable inertia resultant force sees also the paper " the synthetic pre-test of ripple disable inertia resultant force and vibration principle of propeller " that the inventor writes.
Below in conjunction with accompanying drawing the present invention is described in further detail
