Načela oblikovanja lopata so zelo odvisna od vrste in ravni predvajalnika . Načela vključujejo moč, ravnanje, udobje in mehansko okvaro . V idealnem primeru bi morali biti vsi loparji za te meritve maksimirani, na koncu pa je treba izbrati kot najpomembnejše metrike v obliki {2}
Moč
The first design principle is "use a network cable for more power". The mesh cable is able to recover about 90% of the deformation energy after being impacted, while the ball alone (rebounding on a hard surface) can only recover 45% of the energy (Brody, 1995). In addition, the energy of the deformation of the racket frame is not returned to the ball in time, and increasing the energy of the ball pomeni, da največja deformacija neto črte, ko je prizadeti kateri koli lopar, poveča moč več kot deformacija teniške kroglice ali okvirja . v 70. letih 20. stoletja, po nastanku izjemno velikih lopov, načelo omejitve velikosti, ki se je začela uporabljati, kar je trenutna načela, ki se je začela uporabljati {{9}, ki se je začela uporabljati {{9. measured in both parts of the frame. Later attempts to maximize the size of the cable bed focused on adopting a square racket face shape rather than a simple round shape. This resulted in a long length of all the network cables, but there were structural limitations, the frame became difficult to manufacture, not strong enough, and did not look and feel good. Many manufacturers have adopted larger Grometi, ki omogočajo, da se učinkovita velikost kablovskega dna razširi na zunanjo stran okvirja . Drug dejavnik, ki vpliva na moč, je masna porazdelitev, čeprav je masno porazdelitev težko doseči optimalno vrednost, vendar je načelo razmeroma preprosto, to je, da lahka kroglica hitro zavije hitrost, poveča hitrost žoge; Težki loparji na drugi strani počasi zamahnejo, vendar lahko zaradi povečane mase privedejo tudi do povečanja hitrosti žoge, še posebej, če se poveča povečana masa do točke udarca . Zato bi moral biti lopar zasnovan tako, da je dovolj majhen, da se z visokimi hitrostmi zamahne in hkrati zaostaja, da bi dovolj mase za optimizacijo mase, da bi optimizirali uporniško žogo {15}
Upravljanje
Majhne glave in okvirji z visoko torzijsko stabilnostjo imajo boljše ravnanje, ker je kot odklonski kot žice in okvirja manjši . udarci zunaj središča lopata ustvarijo večji kot odklona, kar bo povzročilo, da se žoga odmika od popolne površine, ki jo je pobegljil, da bi se pomeril po gladki površina Narediti veliko napako pri igranju na terenu . visok odpornost proti torziji povzroči manj zasuka lopata v roki, kar ima za posledico natančnejšo udarno točko . Ta točka pri ločevanju omrežnih kablov vpliva tudi na ravnanje in lahko je potrebno, da se maso poveča z dobrim twist -om, da bi lahko ustvarili maso, ki bi bila majhna glava, da bi mazalo male, kar je treba, da ustvarijo majhno glavo. Okvir lopata (ob 3. uri in 9. uri) . gostejša napetost kabla povzroči učinkovitejšo napetost kabla, manj kotnega odstopanja in manj vrtenja, kar je pomembno za nekatere udeležence .
Udobje
Every tennis player has their own different feelings about the comfort of using a racket, which makes it difficult to translate player feedback into actual design parameters. So far, the players' attention has been focused on reducing the impact on the racket and the resulting swing amplitude. Stiffer rackets tend to have lower shock resistance than older thumb rackets used by previous players, so various add-ons are used to provide additional shock resistance. The stiffer racket has a louder sound when struck, which most players don't like, so a shock rope is used. Ways to reduce impact include moving the center of the hit to the center of the racket and increasing the mass of the frame. Other factors related to comfort are the polishing of the surface of the racket and the material of the handle of the handle, for which Proizvajalec ima standardni postopek in metodo .
Mehanska okvara
Rackets used in high-level competitions are usually designed to be as long as possible within the required range, and the introduction of carbon fiber has made a huge leap forward in the performance and strength of the racket, and the internal strength problem of the racket is mainly related to the connection between the body of the racket, the closing part and the tip part of the racket, where the force from the net cable is the greatest, but most manufacturers have solved this problem by reinforcing this part. The market demand for high-quality and efficient rackets forces manufacturers to improve their structural design as much as possible, resulting in complex and special racket types that can adapt to different impact conditions. In the case of modest reduction in strength, most ways to reduce mass are to use pre-impregnated blanks with low resin content, use a smaller layer of paint, and remove the lining and expansion material, ki zagotavlja tlak znotraj abraziva ., ko so bili testirani, so ti loparji zaradi nenormalnih obremenitev zelo krhki, saj niso bili zasnovani za nenormalne napetostne pogoje . Ključ za ta postopek je uporaba ustreznih metod testiranja, ki so zasnovane med igrami, ki se uporabljajo med igram {7}
